KerryG:
Hi Everyone, let’s get the chat started! Welcome to our live discussion with our BT Infinity experts.
7:01
KerryG:
Today we are joined by Charles and Martin from the Infinity team. Welcome everyone!
7:01
KerryG:
Today’s chat is tech focused on BT Infinity, so if you have any individual service queries, we can’t answer them during the chat, sorry. Those queries can be raised in the forum as normal. This chat is focused on the Infinity service itself, all comments will be moderated and the usual forum terms apply.
7:01
Charles:
Hi everyone!
7:02
KerryG:
We have our first question...
7:03
Comment From GedGed:
my wired infinity speed is 54 kps but I can only get 20 when wireless - any way I can improve the wireless speed - Thanks
7:04
KerryG:
We're typing up the answers, so bear with us as we get the answers through to you...
7:05
Charles:
Hi Ged
• Upgrade your computer to ‘N’ standard wireless hardware. If needed, buy a suitable N wireless adaptor from BT atwww.bt.com/nwireless
• Keep your computer streamlined eg. by running our ‘PC Healthcheck’ app (part of BT’s Desktop Help software atwww.bt.com/desktophelp)
• Reserve wireless for mobile devices, use Ethernet for main computer
• Consider powerline adaptors for longer ranges

hi all
7:06
KerryG:
Hi gooch - thanks for your question, but this is an Infinity tech chat so we need to keep it on topic if you post in the Phones board there's lots of helpful community members that will help you out with your query
7:07
Comment From Neil Potter
How soon after an exchange goes live with Infinity will BT allow other providers to sell Fibre To The Cabinet services from that exchange? My existing ISP is waiting to announce pricing details to me so I can make an informed choice. Thanks
7:08
KerryG:
Hi John Good to see you on the chat - who else is here?
7:09
Comment From Chris
Hello world.
7:10
Comment From Helen
hi all.
7:11
Comment From Paul
Are we able to get fastpath on BT infinity,or will this ever be available ?
7:12
Martin S.:
i Neil. When Openreach enables an exchange for fibre, all internet service providers are able to use that service equally - so other ISPs should be able to offer their fibre products at the same time as BT Retail's Infinity product
7:12
KerryG:
Thanks for all the great questions coming through guys... answers being typed as we speak!
7:13
Charles:
Hi Paul, We don't support Fastpath on BT infinity at the moment, I'm afraid.
7:13
Comment From Helen
I've recently upgraded to Infinity 2. The ethernet connection is fine, but the wifi is constantly dropping. I have an old Homehub 2 , which we had for total broadband, will it work, so I can test the wifi.
7:14
Comment From Simon
Hi all
7:15
Martin S.:
Neil - also its worth remembering that when an exchange is enabled for fibre, this does not automatically mean that all cabinets and lines connected to that exchange are also enabled, which might explain if your exchange has been enabled but your line is not appearing as eligible yet
7:16
Comment From Kevin
Whats the upgrade path from fttc to fttp does it mean a new contract or can we just expect it to migrate?
7:17
KerryG
Out of interest...are those on the chat existing Infinity customers or people thinking about it?
7:18
Charles
Hi Helen, your wireless should work ok on your Hub 2, though our more recent Hub 3 is better. If you're expereincing drop outs, it's usually a sign of radio interference. Have you any powerline adaptors you could use instead?
7:18
Comment From Neil Potter
Thanks Martin - Workmen recently dug up the path outside my driveway to install FTTC so I know it's there My exchange goes live on 30th June - I can't wait!I have another question: I'm in the process of consolidating my TV, Telephone and Broadband into one bundle. The "BT Vision Unlimited" looks ideal.
7:19
Comment From Paul
Is there a estimated date that fast path will be available ?
7:19
Martin S.
Hi Kevin - Due to the structure of how fibre has been deployed, your line will either be FTTC or FTTP; there is no way to change your technology type. If you mean 'how do you move to the faster 80mb product (on FTTC)?', this can be done using the links on BT.com
7:19
Comment From Helen
I'm an existing customer.
7:19
Charles
No, 'fraid not, Paul.
7:19
Comment From Neil Potter
thinking about re-joining BT just for Infinity product(s)
7:19
Comment From Paul
existing customer here
7:20
Comment From Chris
I've recently ordered my Infinity package, installation is due the 22nd.
7:20
KerryG
Great to see you all on here... roll on the 22nd for you Chris
7:20
Comment From Kevin
Why are you fitting 2 separate items a modem and a wireless router? cant we have a combined unit, without the need for 2 adaptors and sockets its not the tidiest install
7:21
Comment From Chris
Regarding the Infinity installation, is it mandatory for the BT O/R Engineerer to have access to your PC?
7:22
Martin S.
Hi Chris - It is not mandatory, but we recommend allowing the engineer to show you on your own equipment your fantastic new speeds!
7:22
Comment From Simon
hi, im trying to setup port forwarding to my old draytek, as it has more powerful wirelelss capabaility then the bt homehub, is it possible
7:23
KerryG
Hi Simon - that sounds like a great question for the forum boards, the Draytek is not a BT product so we can go into detail here in this chat, but there will be lots of people who i'm sure can help in the forum.
7:24
Charles
Evening Kevin, for BT Infinity is based on thecurrent FTTC product offered by BT Openreach, which comprises the VDSL modem provided by Openreach and the Home Hub 3 provided by Retail. If/when Openreach move to supporting a single box solution, then we would look to moving to that. Openreach will shortly be trialling this.
7:24
Comment From Helen
I've already checked there's nothing interfering with the Hub.
7:24
Comment From Helen
I don't have a Hub3, both the one that is currently connected, and the old one I have in the box are Hub 2.
7:25
Comment From Chris
Yes, going from 3mb to an estimated 50mb+ is quite the upgrade, I would even be happy if it was merely a 10MB upgrade. - If I remember correctly FTTC is around(if not the same) price as standard broadband these days.
7:26
Charles
Helen - could you post your issue in the Bt Infinity forum and one of our mods will look into this for you.
7:26
Comment From Kevin
My install is planned for the 28th May my question is i have my master socket downstairs directly below the room i want my fttc modem installed is it possible to have the modem upstairs with the extension cable ?
7:27
Comment From Mike B
I have an istalation question. I understand that the modem for Infinity needs to be sited close to the BT phone socket. Am I right in thinking that the modem is then connected via a Cat 5/6 cable to the wireless router situated elsewhere in the house? Does this impact on the speed?
7:27
Comment From Helen
Ok charles, I will do..
7:28
Comment From Neil Potter
On the subject of Powerline Adaptors (PA's) - I have a unique setup here at home whereby I would need to utilise 4 x PA's. Are there any known performance issues sharing data, experiencing latency or dropped packets from Desktop PC's all connected via PA's at the same time?
7:28
Martin S.
Kevin / Mike B: The engineer can use an extension cable up to 30m long to help position your equipment where you want it - this should not affect your speed.
7:29
Comment From Eric Simpson
I have bt broadband .. I am currently getting 3M download. I have two "estimates" from the BT site. One says I should get between 10-17 ... the other which does some sort of check/diagnostic (and appears to be the real thing) says I should get between 1-4. We are meant to get Infinity next month. How would that impact me?
7:31
Charles
Hi neil - good question. I've found from experience that powerline performance is very much dependent on the adaptor manufacturer and your home environment, specifically how 'clean' your electrical spectrun is. All I can say is give it a try. That said, i would always recommend an Ethernet connection for the fastest and most stable speeds.
7:31
Martin S.
Hi Eric. You can find your predicted BT Infinity speed (if it is available on your line) at bt.com/infinity and entering your number into the availability checker
7:31
Comment From Simon
hi, really I'm just asking a tech question - can the bt home hub port forward?
7:32
Comment From Eric Simpson
Does my question pop up only when it comes up the queue?
7:33
KerryG
Hi Eric - Yes, they will flow in as they get answered - it helps to make the chat easier to read as the Q & As flow in a reasonable order.
Great questions coming through... lots more to get through...been a quick 33 mins!
7:33
Charles
Hi simon - I'm assuming you're talking about the Hub 3 (our latest Hub). Yes, it does support port forwarding. You can set this up via the configuration menu in your Hub. See instructions in your Hub user guide for how to do this.
7:33
Comment From Glynn
Will BT Retail be selling fibre-on-demand at an affordable cost for home users?
7:35
Comment From guilbo
Hello folks. I have a question. We often see on the Vision forum that users start having problems with their service on Infinity that they weren't having with ADSL. Do you know of anything that would cause this?
7:35
Martin S.
Hi Glynn, we are currently reviewing Fibre on Demand and have not yet announced any pricing or availability details.
7:36
Comment From Chris
How reliable is that checker by chance?
7:37
Comment From Paul (Heanor)
Also I am booked for installation on 22nd May
7:37
KerryG
Nice one Paul You'll be enjoying super fast speeds then too
7:38
Charles
HI guilbo - I'm not aware of any technical issues for Vision customer regrading to Infinity. We have hundreds of orders go through each week. If the problem persists, I would suggest customers contact the Infinity helpdesk.
7:38
Comment From Neil Potter
Thanks for your reply Charles - If I could ask, the PA's you supply with the current BT Vision boxes are manufactured by Simpler Networks - would I need to purchase identical PA's from the same manufacturer for extending my network? Will BT Retail sell me these as an additional extra? This will be my last question - I feel I have been fortunate to have two answered already
7:39
Martin S.
Hi Chris - The speeds estimated in the checker are a very good indication of actual speeds, but we can only know the exact speed once installed.
7:39
Comment From Eric Simpson
it says not available yet. I am just frustrated because I get faster speed from my little Android phone using it as a hotspot. If there is a bottleneck somewhere in the system, would fibre really make a difference
7:41
Comment From Kevin
I have been given the estimate of 59.4Mb download 20.0Mb upload will this be accurate?
7:42
Charles
Hi neil - yes you should always stick to the same model for all your PA's. I am pretty sure that additional Vision PA's can be bought from the BT Shop, and these should be fine. I have had 70mbps out of mine! seewww.bt.com/shop
7:43
Martin S.
Eric - Generally fibre can make a very significant difference to overall speeds, though individual increases can't be guaranteed. If / when it becomes available on your line, the checker will tell you how much of a difference it could make to you.
7:43
Comment From Chris
I'm assuming it's based on the length of copper from my house to the Green Cab. - The exchange is 2miles~ away from me and the said Cab. Will this also effect my speed?
7:45
Charles
Hi Kevin - our estinmates are as accurate as we can make them, but your actual speed will depend on your underlying phone line speed. We will only know your true speed once Infinity is live - it will then train to your optimal line speed, which should be approx as shown by your prediction.
7:45
KerryG
Glad to see you all keeping Charles and Martin busy here... keep the questions coming in, we're in the last 15 mins now...
7:45
Martin S.
Chris - Yes, your speed is primarily affected by the total amount of copper between you and the exchange. With FTTC fibre products, the old copper between the exchange and the cabinet is replaced by fibre, meaning less copper overall and faster speeds.
7:45
Comment From Lewis
Why does DLM take so long to take interleaving off?
7:45
Comment From Neil Potter
Thank you very much for your time this evening Charles / Martin / Kerry. It's nice to see these types of events becoming more accessible to your customers and I for one feel I've got a lot from joining you all this evening
7:46
Martin S.
Thanks Neil - you're welcome!
7:46
KerryG
Great stuff Neil.... glad you've found it useful.
7:46
Comment From Chris
The Cab is 500-600 metres away from me, and according this graph the the BT estimated speed is just right on that.
7:47
Charles
Hi Lewis - DLM will apply interleaving only if it detects an ustable line. It will not apply interleaving unless it is warranted.
7:47
Comment From Kevin
I guess when i get my infinity installed a lot of sites and links will still be on dsl or adsl+ or even slower and the speed my end wont improve the speed there end ie my speed will depend on the site i visit and there upload speed for my download speed?
7:48
Comment From Dom
I am moving to BT infinity, but I had to order my line and then wait for it to be activated before ordering infinity. Is this a technical issue or a process at BT issue?
7:49
Charles
Evening Dom. It's a process issue - we can only provide Infinity once a Retail line is up and running.
7:49
Comment From William Sinclair
Hi guys. I've upgraded to Infinity 2 with an estimated max download of 49.5 Mbps however my IP profile hasn't budged from the Infinity 1 value of ~30. Any thoughts?
7:50
Comment From Dom
Thanks - this is a great service BT, keep it up!
7:51
Martin S.
Hi Kevin - yes, some websites that you visit may not be able to keep up with your superfast speeds! We aim to give you the best speeds at your end, but sadly there may sometimes be bottlenecks in the wider internet.
7:51
Charles
HI William - sorry for the delay in responding. Best thing to do is to reboot your Hub, then it should pick up the new speed. If not, contact the Infinity forum.
7:51
Comment From Lewis
What would cause an unstable line?
7:53
KerryG
@wiesiek @ Martin (not S) thanks for your questions, but as they're individual issues we can't pick them up as part of this chat. Please post in the forum and we can help.
7:53
Comment From guilbo
Apologies in advance for my ignorance. If Infinity is installed does the 'phone continue to use copper all the way to the exchange or does this also go over fibre?
7:54
Charles
Hi lewis - the most common cause is interference on your phone line, in which case DLM will moderate your BB speed until the line stablises. There'smore lot of info on this at the Infinity FAQs on BT.com
7:54
Martin S.
Hi Guilbo - good question - yes, the phone still uses the copper.
7:54
Comment From Paul (Heanor)
Will downloading from such as Xbox market place or apple store as examples max out the connection?
7:55
Comment From Kevin
Thanks to Martin, Kerry, and Charles for all your answers to the questions very much appreciated and a credit to BT Kevin
7:55Hi everyone
Just a reminder that we have our Infinity Expert chat this evening at 7pm. If for any reason you can't make the chat, you can PM me your questions in advance and we'll try to include them. There will also be a replay available of the chat here on the same post after the event.
Thx

Ask the Expert Live Discussion – YouView from BT
Hi All
I’m pleased to announce our next live discussion with some BT experts! It's about our latest new product, YouView from BT, and we thought this would be a great chance to get our YouView experts onto the community to tell you a bit more about that and answer any YouView from BT-related questions you may have.
Our experts Sam, Rob and Francesca will be chatting with you on Thursday 06/12 at 7pm.
For anyone who wasn't able to join us for the chat, we have included the chat transcript below
6:58
Nigel Elliott:
Hi Everyone, let’s get this chat started! Welcome to our live discussion with our experts about YouView from BT
6:58
Nigel Elliott:
Today we are joined by Rob, Sam, Francesca and Gary. Welcome everyone! Today’s chat is tech focused on YouView from BT, so if you have any individual service queries we can’t answer them during the chat, but do raise them in the forum as normal.
6:58
Nigel Elliott:
This chat is about the YouView from BT service itself, all comments will be moderated and the usual forum terms apply.
7:03
Comment From Phil
Hi guys I'm interested in getting this but wondered what the connection options are - does the box support HDMI, Scart and Component?
7:03
Nigel Elliott:
Hi Phil, good question our experts are typing up a reply right now
7:07
Gary:
Hi Phil, the box supports HDMI and SCART but not Component.
7:08
Comment From Guilbo
Hi folks. We have heard much about live channels launching on Vision at some point. Will these be available on YouView Vision player at the same time and will they be recordable?
7:10
Nigel Elliott:
Thanks for the question Guilbo - keep them coming guys!
7:11
Gary:
Hi, we are launching live channels on our Vision+ box soon and are also working on live channels on the YouView box. These will be available later in 2013
7:12
Gary:
You will be able to record them when they become available
7:13
Comment From Guilbo
Thanks, Gary. Will Sky Sports become available on YouView when you launch the linear channels?
7:14
Comment From Dee
Hi guys, will YouView usage count towards my broadband usage?
7:16
Gary:
We will release the full channel line up next year
7:16
Nigel Elliott:
Thanks Gary, does that answer your questions Guilbo?
7:18
Comment From Guilbo
Yes, mostly.
7:21
Comment From Dee
OK thanks. If I have BT Vision can I still have YouView?
7:21
Sam:
Hi Dee, Yes, with a BT Vision subscription, all your on-demand viewing (including all Vision on-demand, all catch-up as well as players such as NowTV) is exempt from any broadband usage allowance. So you don't need to worry how much you watch.
7:22
Francesca Mahoney:
Hi Dee, thanks for your question. If you have had your BT Vision+ box for more than 12 months then you can get YouView for £49.
7:24
Comment From b-1
Any word on when manual padding will become available on YouView?
7:25
Francesca Mahoney:
Hi Dee again - just to add - when you take YouView for £49 you will recontract your TV and broadband subscriptions. Thanks!
7:27
Comment From Guilbo
Some people have been experimenting with running a Vision and a YouView box simultaneously. Can they coexist? Also are their any plans for multiroom with YouView.
7:28
Nigel Elliott:
Thanks for the questions b-1 and Guilbo, your replies are on their way shortly.
7:30
Sam:
Hi Guilbo The use of two or more YouView/ Vision boxes on the same broadband line is not supported. If you plug in a YouView box from BT, your old BT Vision+ box may stop working and so you should watch the recordings on your old box before plugging in your new one. We hope to introduce a multiroom offering in 2013
7:31
Nigel Elliott:
Out of interest, do the people watching this chat already have YouView or are you thinking about signing up?
7:33
Sam:
also see FAQ's www.bt.com/help/youview
7:34
Comment From Dee
Hi me again OK so, if I sign up to YouView with BT, what happens when my contract with BT ends? Will the box still work?
7:35
Rob:
Hi b-1, Are you having problems with clipped recordings? YouView are looking at why this is sometimes happens and are working with broadcasters to improve the accuracy of their recording signals but they are not planning to add padding at the moment.
7:37
Comment From Guilbo
Thanks, Sam, that's interesting stuff. I don't have YouView (yet) but it is something that I will most likely move on to at some point. To follow on from a previous question, if I am in contract for Broadband, but out of contract for Vision, can I still get YouView for 49 squids by taking out a contract to Vision Player?
7:38
Nigel Elliott:
Just typing up your replies now guys
7:39
Sam:
Hi Guilbo, yes you can get the Box for £49 if you are in contract on your BB but out of contract on your Vision, taking the Youview box for £49 will recontract your Vision for another 12 months.
7:39
Francesca Mahoney:
Hi Dee again
At the end of your contract the YouView box will still function but we hope you'll want to stay with your BT Vision subscription so you'll have access to all of our On Demand content and none of your YouView usage will count towards your broadband allowance.
7:42
Comment From Guilbo
Thanks folks. This is really helping to firm up on some things which up to now have been sketchy.
7:42
Francesca Mahoney:
No probs Guilbo
7:44
Nigel Elliott:
No problem Guilbo, if you have any other questions keep them coming!
7:44
Rob:
Hi All, Did you hear that YouView have just launched a free iPhone app to let you set a recording on your box while you're on the move? It's not yet available for Android phones. If you have an iPhone 3GS or later, an iPod touch or iPad, it's well worth downloading.
7:47
Comment From Steph
Hi Rob, if I have YouView from BT will I still be able to get BT Player programs via the app?
7:47
Comment From MikeC
Are there any plans to offer boxes with large hard-drives and can I get 3D content via BT Vision on YouView?
7:48
Comment From Guilbo
Interesting about the app. Will the services on it ever be able to stream to mobile devices, I wonder?
7:49
Nigel Elliott:
Thanks folks, you'll get your replies very soon
7:53
Rob:
Hi Steph & Guilbo, The YouView app is just for setting recordings at the moment. It will get better over time I'm sure, but streaming to mobile devices won't be possible for a while I expect.
7:56
Nigel Elliott:
Just a couple of minutes left guys, if you have any other questions now's the time to submit them!
7:56
Sam:
Hi Mike, we are looking into the possibility of bringing 3D content on Youview from BT in the future. The Youview Box from BT is 500GB but the High Street Retailers have both 500GB and 1TB.
7:57
Comment From Linz
Just purchased bt freestyle 750 duo and one of the handsets constantly says searching please help
7:58
Nigel Elliott:
Hi Linz, have a look over at the Phones board - one of our community members will be able to offer advice with this
7:59
Comment From James
On the mobile app - any plans to support windows phones?
8:00
Comment From MikeC
ok cheers thx guys
8:00
Comment From Guilbo
You were originally going to use a Pace box. Is the Humax a stopgap or is this now the permanent offering. Will there ever be a choice of boxes from BT?
8:00
Sam:
Hi James, sorry no not at the moment but it may be something Youview do in the future
8:01
Nigel Elliott:
No problem Mike
8:03
Nigel Elliott:
Thanks Guilbo, the experts are typing up your answer.
8:05
Rob:
Hi Guilbo, The YouView from BT box is a Humax box and as soon as any other other box types are announced we will let you know.
8:06
Comment From Guilbo
Cheers, Rob. Think that's me out of questions now, so thanks very much for your time. It has been useful.
8:07
Nigel Elliott:
Cheers Guilbo, glad you found it useful.
8:07
Nigel Elliott:
Hi folks, thank you very much, that was our last question.
8:07
Nigel Elliott:
Big thanks to Rob, Francesca, Sam and Gary for joining the chat and all you guys for posting some very interesting questions. It’s been a great session, I hope you’ve found it useful. I will close the chat now, but it will be available on the replay if you want to re-read any of the comments.

Yes its is possible. Connect the storage array to the fabric interconnects using two 10GB links per storage processor. Connect each SP to both fabric interconnects and configure the ports on the fabric interconnect as “Appliance” ports from UCSM
For more information on how to connect Netapp storage using other protocols like iSCSI or FCOE please check the url below.

Actually we have UCS 6248 fabric interconnect - first twelve ports are enabled and same in Cisco UCS Manager.
But when more port will be active by expansion module then UCSM can manage that too or need any other licence for UCSM too? -
Ask the Expert: Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI
Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI with Vishal Mehta and Manuel Velasco.
The current industry trend is to use SAN (FC/FCoE/iSCSI) for booting operating systems instead of using local storage.
Boot from SAN offers many benefits, including:
Server without local storage can run cooler and use the extra space for other components.
Redeployment of servers caused by hardware failures becomes easier with boot from SAN servers.
SAN storage allows the administrator to use storage more efficiently.
Boot from SAN offers reliability because the user can access the boot disk through multiple paths, which protects the disk from being a single point of failure.
Cisco UCS takes away much of the complexity with its service profiles and associated boot policies to make boot from SAN deployment an easy task.
Vishal Mehta is a customer support engineer for Cisco’s Data Center Server Virtualization TAC team based in San Jose, California. He has been working in the TAC for the past three years with a primary focus on data center technologies such as Cisco Nexus 5000, Cisco UCS, Cisco Nexus 1000v, and virtualization. He has presented at Cisco Live in Orlando 2013 and will present at Cisco Live Milan 2014 (BRKCOM-3003, BRKDCT-3444, and LABDCT-2333). He holds a master’s degree from Rutgers University in electrical and computer engineering and has CCIE certification (number 37139) in routing and switching and service provider.

Thank you for asking this question. Most common TAC cases that we have seen on Boot-from-SAN failures are due to misconfiguration.
So our methodology is to verify configuration and troubleshoot from server to storage switches to storage array.
Before diving into troubleshooting, make sure there is clear understanding of this topology. This is very vital with any troubleshooting scenario. Know what devices you have and how they are connected, how many paths are connected, Switch/NPV mode and so on.
Always try to troubleshoot one path at a time and verify that the setup is in complaint with the SW/HW interop matrix tested by Cisco.
Step 1: Check at server
a. make sure to have uniform firmware version across all components of UCS
b. Verify if VSAN is created and FC uplinks are configured correctly. VSANs/FCoE-vlan should be unique per fabric
c. Verify at service profile level for configuration of vHBAs - vHBA per Fabric should have unique VSAN number
Note down the WWPN of your vhba. This will be needed in step 2 for zoning on the SAN switch and step 3 for LUN masking on the storage array.
d. verify if Boot Policy of the service profile is configured to Boot From SAN - the Boot Order and its parameters such as Lun ID and WWN are extremely important
e. finally at UCS CLI - verify the flogi of vHBAs (for NPV mode, command is (from nxos) – show npv flogi-table)
Step 2: Check at Storage Switch
a. Verify the mode (by default UCS is in FC end-host mode, so storage switch has to be in NPIV mode; unless UCS is in FC Switch mode)
b. Verify the switch port connecting to UCS is UP as an F-Port and is configured for correct VSAN
c. Check if both the initiator (Server) and the target (Storage) are logged into the fabric switch (command for MDS/N5k - show flogi database vsan X)
d. Once confirmed that initiator and target devices are logged into the fabric, query the name server to see if they have registered themselves correctly. (command - show fcns database vsan X)
e. Most important configuration to check on Storage Switch is the zoning
Zoning is basically access control for our initiator to targets. Most common design is to configure one zone per initiator and target.
Zoning will require you to configure a zone, put that zone into your current zonset, then ACTIVATE it. (command - show zoneset active vsan X)
Step 3: Check at Storage Array
When the Storage array logs into the SAN fabric, it queries the name server to see which devices it can communicate.
LUN masking is crucial step on Storage Array which gives particular host (server) access to specific LUN
Assuming that both the storage and initiator have FLOGI’d into the fabric and the zoning is correct (as per Step 1 & 2)
Following needs to be verified at Storage Array level
a. Are the wwpn of the initiators (vhba of the hosts) visible on the storage array?
b. If above is yes then Is LUN Masking applied?
c. What LUN number is presented to the host - this is the number that we see in Lun ID on the 'Boot Order' of Step 1
Below document has details and troubleshooting outputs:

Thank you very much for welcoming me to your expert discussion :) I feel to be in the right place, at the right time. Thank you also for answering question beyond your scope here, much appreciated. The information received will help me to go further as such I have submitted a 5 start rating for your first reply.
That sounds promising about the LMS part so yes, I stay tuned and wait patiently.
Ok, now let’s revert to the actual topic discussed here. Cisco Prime Service Catalog and Process Orchestrator solutions I have briefly read up on this on CCO (where elseJ) and picked out the following quote
---- Quote from the Cisco Prime Service Catalog Data Sheet
Today’s end users want self-service and easy access to IT tools and services.
Simultaneously, organizations are seeking ways to extend their cloud management
platforms beyond self-service delivery of virtual machines and infrastructure resources
while increasing their use of cloud-based solutions to enhance business agility and effectiveness.
Cisco Prime™ Service Catalog offers tremendous benefits to organizations that want to unify the ways in
which all types of IT services are ordered and fulfilled, not just infrastructure requests
---- un quote ---
I try to understand what (at high level of course) happens in the back ground when an order is raised and which vendor solution your product can interact with.
As mentioned in the quoted text, this service catalogue goes beyond the standard infrastructure.
Let’s say, a user wants to deploy a new email services, or in your example, extends or create a new web-portal (i.e. for HR to view and manage holiday, staff absence and benefits).
Your solution will need to interact somehow with the 3rd party vendor application that is capable building such portal I believe.
Without disclosing to many information, I assume the portal is linked to backend VM,s that spin up requested resources (and more magic of course). Perhaps I am mixing this up with another cisco product where a user can go on the portal and spin up virtual Firewalls, virtual Routers can be provisioned in now time.
Out if interest; Is this product also known as Mozart? (project code within Cisco?)
I hope query is ok.
Best wishes

This event lasts through January 31, 2014. Visit this forum often to view responses to your questions and the questions of other community members.Hi Anurag,
Thanks for your questions.
1:Is there change in DB architecture as CUIC is the only option as compared to previous linux version UCCX ?
I assume this is from the tables regarding historical data. The database schema essentially remains the same since UCCX 9.0 had CUIC too and we had a seperate DB Space for CUIC and we still continue with that. The traditional historical tables remain and the replication process remains the same too.
2:Is there any version change for Linux OS used as VOS,
The Linux version is Red Hat Linux 5. To be precise:
[root@uccx10pub /]# cat etc/redhat-release
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
3:Is there any API architecture change in UCCX 10 from previous releases ?
I can answer this more of an overview. The only enhancement in the API side is the introduction of REST API step in the script editor. You can now make REST calls from the script and this ofcourse opens up a whole new world of possiblities.
4:Since from UCCX 10 , we can only use either CAD or Finnesse at one time, whats the impact of changing this after some time in production, let say , i used CAD for 2 months and then i decided to move to Finesse, whats the impact ? or is it a smooth change as switching CUIC and HRC in previoius release ?
For the scenario you mentioned, there is absolutely no problem. The point to note is that the Finesse services are activated/deactivated but the CAD desktop services are ALWAYS running. The only condition to keep in mind is that you can use ONLY ONE type of agent desktop at any time. Also if Finesse is not used and CAD operations are used extensively, it is advisable to shutdown the Finesse service.
5:Is 3rd Party UCS hardware supported by UCCX 10 instead of using Cisco manufactured UCS , can i use HP hardware for Virtualisation ?
Yes, it can be used. This is something called as "Third party specs based specification". The most important things seen for compatibility are:
Inter CPU Model
It it is on thVMWare Hardware Compatibilty List
You can get more information about this on the "Can I use this server?" section of UC Virtualized Hardware page:
http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#.22Can_I_use_this_server.3F.22
6:Is Host name change supported?
Yes, the hostname change is supported. The prcocedure is documented in the UCCX 10.0 Administration Guide:
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_0/configuration/guide/UCCX_BK_W1AF9DDD_00_uccx-admin-guide-10.0.pdf (Pg 168)

Thanks for the topology. The trigger will be different for labelled packet as you would need to mention the values of labels too in the trigger.
Below are two examples of one or two labels being used, it depends on where you are capturing the packet in mplsvpn scenario which will decide teh number of labels being imposed on the packet.
Trigger for one label. (if the router on which you are capturing the packet PHP is being performed)
VPN label - 5678
Source Address - 111.111.111.111
Destination Address - 123.123.123.123
show platform capture elam trigger dbus others if data = 0 0 0 0x88470162 0xE0000000 0 0 0x00006F6F 0x6F6F 7B7B 0x7B7B0000 [ 0 0 0 0xffffffff 0xf0000000 0 0 0x0000ffff 0xffffffff 0xffff0000 ]
Trigger for two labels. (for other core routers)
IGP label - 1234
VPN label - 5678
Source Address - 111.111.111.111
Destination Address - 123.123.123.123
show platform capture elam trigger dbus others if data = 0 0 0 0x8847004D 0x20000162 0xE0000000 0 0 0x00006F6F 0x6F6F7B7B 0x7B7B0000 [ 0 0 0 0xffffffff 0xf000ffff 0xf0000000 0 0 0x0000ffff 0xffffffff 0xffff0000 ]
You can check the labels being used (by using show ip cef <> details) and covert their values to hex and change the trigger accordingly.
I have changed the colors for better understanding. If you notice carefully in the trigger the values for ip address, labels have just been converted to their respective hex values which could be replaced.
Please let me know if this helps.
Thanks & Regards

Thank you for your question.
At current, we do not setup CUCM in a multi-tenant configuration. Each HCS end-customer gets their own unique CUCM cluster, the same goes for Unity Connection and Unified Presence.
There are a few pieces of software that are unique to HCS
1) HCM - F - This component is used to automate the upgrades of the UC applications, produce bundle-based billing reports from the configuration domain, and also automatically provision/configure the Service Assurance architecture so as you deploy HCS to end customers, the monitoring of those configurations is automatically done for you.
2) Prime Central for HCS Assurance - This component is responsible for provides lots of functionality in regards to monitoring the HCS solution. It aggregates data from CUOM, CUSM, DCNM, and vCenter and can display all the events/errors/alarms that those components are reporting. It also has the ability to normalize these errors and forward them to an exisitng alarm management or ticketing system via SNMP traps. It also includes a reatures like fault correlation (root cause analysis) and service impact analysis which allows you to see what services are affected based on the error information that is being reported.
3) This last item is not really a piece of software, but more an advantage over using UC on UCS as opposed to HCS. Within HCS we allow the over subscription of your UCS resources for some of the smaller OVAs where in UC on UCS you would be required to map a vCPU to an entire core. This allows for much greater denisty. Also, the HCS licensing scheme allows for the SP to pool licenses and transfer between the customers as needed where in UC on UCS, these licenses are bound to customers, once purchased.
To answer your last question, we sell HCS to service providers and partners. Partners may need to have customers bring their own PSTN connectivity or partner with an SP to provide PSTN access, but either way, partners are just as capable of providing this service.
Hope that helps. Thanks again Tenaro! -

Another set of good/interesting questions posted. Thanks!
I will try to clarify your doubts.
In the output below both resources (proxy-connections and ssl-connections rate) are configured with a min percentage of resources (column Min), while 'Max' is set to equal to the min.
ACE/Context# show resource usage
Allocation
Resource Current Peak Min Max Denied
-- outputs omitted for brevity --
proxy-connections 0 16358 16358 16358 17872
ssl-connections rate 0 626 626 626 23204
Most columns are self explanatory, 'Current' is current usage, 'Peak' is the maximum value reached, and the most important counter to monitor 'Denied' represents the amount of packets denied/dropped due to exceeding the configured limits.
On the resources themselves, Proxy-connections is simply the amount of proxied connections, in other words all connections handled at layer 7 (SSL connections are proxied, as are any connections with layer 7 load balance policies, or inspection).
So in this particular case for the proxy-connections we see that Peak is equal to the Max allocated, and as we have denies we can conclude that you have surpassed the limits for this resource. We see there were 17872 connections dropped due to that.
ssl-connections rate should be read in the same manner, however all values for this resource are in bytes/s, except for Denied counter, that is simply the amount of packets that were dropped due to exceeding this resource.
For your particular tests you have allocated a min percentage and set max equal to min, this way you make sure that this context will not use any other additional resources.
If you had set the max to unlimited during resource allocation, ACE would be allowed to use additional resources on top of those guaranteed, if those resources were available.
This might sound a great idea, but resource planning on ACE should be done carefully to avoid any sort of oversubscription, specially if you have business critical contexts.
We have a good reference for ACE resource planning that contains also description of all resources (this will help to understand the output better):
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/configuration/virtualization/guide/config.html#wp1008224
1) When a resource is utilized to its maximum limit, the ACE denies additional requests made by any context for that resource. In other words, the action is to Drop. ACE should in theory silently drop (No RST is sent back to the client). So unless we changed something on the code, this is what you should see.
To give more context, seeing resets with SSL connections is not necessarily synonym of drops. As it is usual to see them during normal transactions.
For instance Microsoft servers are usually ungracefully terminating SSL connections with RESET. Also when there is renegotiation during an SSL transaction you may see RESETS, but this will pass unnoticed for end users.
2) ACE will simply drop/ignore new connections when we reach the maximum amount of proxied connections for that context. Exisiting connections will continue there.
As ACE doesn't respond back, client would simply retransmit, and if he is lucky maybe in the next attempt he will be able to establish the connection.
To overcome the denies, you will definitely have to increase the resource allocation. This of course, assuming you are not reaching any physical limit of the box.
As mentioned setting max as unlimited might work for you, assuming there are a lot of unused resources on the box.
3) If a new connection comes in with a sticky value, that matches the sticky entry of a real server, which is already in MAXCONNS state, then both the ACE module/appliance should reject the connection and that sticky entry would be removed.
The client would at that point reestablish a new connection and ACE would associate a new sticky entry with the flow for a new RSERVER after the loadbalancing decision.
I hope this makes things clearer! Uff...
Regards,
Telmo -

As you would aready know, the UCCX will send an AXL request (within the SOAP envelope) to the CUCM to create this RP. Looking at the existing code, there does not seem to be a method where we are differentiating between CFB_internal and CFB_external while sending this request.
We have taken this as an enhancement request and also spoken to the business unit about the same. It has been added to the roadmap, we will reach out to you offline to understand the business case so that the process can be expedited if needed.

Ask the Expert: Different Flavors and Design with vPC on Cisco Nexus 5000 Series Switches
Welcome to the Cisco® Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco® NX-OS.
The biggest limitation to a classic port channel communication is that the port channel operates only between two devices. To overcome this limitation, Cisco NX-OS has a technology called virtual port channel (vPC). A pair of switches acting as a vPC peer endpoint looks like a single logical entity to port channel attached devices. The two devices that act as the logical port channel endpoint are actually two separate devices. This setup has the benefits of hardware redundancy combined with the benefits offered by a port channel, for example, loop management.
vPC technology is the main factor for success of Cisco Nexus® data center switches such as the Cisco Nexus 5000 Series, Nexus 7000 Series, and Nexus 2000 Series Switches.
This event is focused on discussing all possible types of vPC along-with best practices, failure scenarios, Cisco Technical Assistance Center (TAC) recommendations and troubleshooting
Vishal Mehta is a customer support engineer for the Cisco Data Center Server Virtualization Technical Assistance Center (TAC) team based in San Jose, California. He has been working in TAC for the past 3 years with a primary focus on data center technologies, such as the Cisco Nexus 5000 Series Switches, Cisco Unified Computing System™ (Cisco UCS®), Cisco Nexus 1000V Switch, and virtualization. He presented at Cisco Live in Orlando 2013 and will present at Cisco Live Milan 2014 (BRKCOM-3003, BRKDCT-3444, and LABDCT-2333). He holds a master’s degree from Rutgers University in electrical and computer engineering and has CCIE® certification (number 37139) in routing and switching, and service provider.

Because of the volume expected during this event, Vishal and Nimit might not be able to answer every question. Remember that you can continue the conversation in the Network Infrastructure Community, under the subcommunity LAN, Switching & Routing, shortly after the event. This event lasts through August 29, 2014. Visit this forum often to view responses to your questions and the questions of other Cisco Support Community members.Hello Gustavo
Please see my responses to your questions:
Yes almost all routing protocols use Multicast to establish adjacencies. We are dealing with two different type of traffic –Control Plane and Data Plane.
Control Plane: To establish Routing adjacency, the first packet (hello) is punted to CPU. So in the case of triangle routed VPC topology as specified on the Operations Guide Link, multicast for routing adjacencies will work. The hellos packets will be exchanged across all 3 routers and adjacency will be formed over VPC links
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/operations/n5k_L3_w_vpc_5500platform.html#wp999181
Now for Data Plane we have two types of traffic – Unicast and Multicast.
The Unicast traffic will not have any forwarding issues, but because the Layer 3 ECMP and port channel run independent hash calculations there is a possibility that when the Layer 3 ECMP chooses N5k-1 as the Layer 3 next hop for a destination address while the port channel hashing chooses the physical link toward N5k-2. In this scenario,N5k-2 receives packets from R with the N5k-1 MAC as the destination MAC.
Sending traffic over the peer-link to the correct gateway is acceptable for data forwarding, but it is suboptimal because it makes traffic cross the peer link when the traffic could be routed directly.
For that topology, Multicast Traffic might have complete traffic loss due to the fact that when a PIM router is connected to Cisco Nexus 5500 Platform switches in a vPC topology, the PIM join messages are received only by one switch. The multicast data might be received by the other switch.
The Loop avoidance works little different across Nexus 5000 and Nexus 7000.
Similarity: For both products, loop avoidance is possible due to VSL bit
The VSL bit is set in the DBUS header internal to the Nexus.
It is not something that is set in the ethernet packet that can be identified. The VSL bit is set on the port asic for the port used for the vPC peer link, so if you have Nexus A and Nexus B configured for vPC and a packet leaves Nexus A towards Nexus B, Nexus B will set the VSL bit on the ingress port ASIC. This is not something that would traverse the peer link.
This mechanism is used for loop prevention within the chassis.
The idea being that if the port came in the peer link from the vPC peer, the system makes the assumption that the vPC peer would have forwarded this packet out the vPC-enabled port-channels towards the end device, so the egress vpc interface's port-asic will filter the packet on egress.
Differences: In Nexus 5000 when it has to do L3-to-L2 lookup for forwarding traffic, the VSL bit is cleared and so the traffic is not dropped as compared to Nexus 7000 and Nexus 3000.
It still does loop prevention but the L3-to-L2 lookup is different in Nexus 5000 and Nexus 7000.
For more details please see below presentation:
https://supportforums.cisco.com/sites/default/files/session_14-_nexus.pdf
DCI Scenario: If 2 pairs are of Nexus 5000 then separation of L3/L2 links is not needed.
But in most scenarios I have seen pair of Nexus 5000 with pair of Nexus 7000 over DCI or 2 pairs of Nexus 7000 over DCI. If Nexus 7000 are used then L3 and L2 links are required for sure as mentioned on above presentation link.
Let us know if you have further questions.
Thanks,
Vishal -

Personal testing - Why is the 2.4GHz range less than the HH3 when at a distance from the hub, but better close up than the HH3?
7:10
JacquiBT:
Thanks DS, Dave is answering this now for you
7:10
[Comment From George George : ]
Will the 'Home Network' page show a HH4 instead of the Current image of the HH3?
7:11
JacquiBT:
Thanks George, Sam will answer that for you
7:11
Sam:
Hi George, the HH4 image will be displayed in place of the HH3 in the next firmware release
7:12
Dave:
Thanks again DS - you shouldn't find that, but this can depend on a lot of different factors in the home. I've found mine to be a bit better actually! But it should be pretty much the same for most customers.
7:12
Sean Donnelly:
Did you know the Hub 4 has Smart Setup?
Easy set up in just a few minutes. No CD or computer needed, it's all online and works on any device. Set up your Hub 4 router and access all your free extras like BT Cloud and BT Family Protection in just a few clicks.

[Comment From DS DS : ]
Is it possible for BT to allow us to move the BTWifi SSID's to another channel, leaving our own SSID on a less congested channel?
7:12
Dave:
Hi imjolly, sorry for the delay, Emma asked me to reply on her behalf. We have made the stats in the Hub manager simpler for customers to understand, we were reacting to feedback that it was too general for the wide range of customers and tech understandings.

JacquiBT:
Hi JamesS. Dave will reply to your question
7:14
Emma:
Hi imjolly, we have made the stats in the Hub manager simpler for customers to understand, we were reacting to feedback that it was too general for the wide range of customers and tech understandings.
7:15
Sam:
Hi DS, moving BT Wifi SSID's to another channel is not possible on the HH4. However, we are looking closely at the wi-fi SSID's the hub broadcasts to see whether we can improve this experience.
7:15
Dave:
Hi James, 5GHz maximum data transfer rate of 300Mb/s; this will tend to translate as an optimal actual speeds of up to 100 Mb/s - depending on lots of factors in your home
7:15
[Comment From George George : ]
Why did you remove the built in plastic wireless info tab with a card?
7:15
JacquiBT:
Hi George, Dave is going to reply to that question
7:16
Dave:
Hi George - this was part of the design process, we've tried to make it even easier for customers to find their wireless information. Now it's not integrated it's a little bit more accessible.
7:16
[Comment From thebennyboy thebennyboy : ]
I currently have the HH3 and would like to know what noticable difference it will make having a HH4 over a HH3? We use the ethernet ports and the wireless.

How much power does the home hub 4 use?
7:24
JacquiBT:
Hi Winston. Dave will respond to your question
7:24
Sam:
Hi Josh, we are aware of this issue. This is a problem with the Xbox rather than the HH4 but something we are reviewing together.
7:24
Emma:
Hi the bennyboy, the main advantages of the hub 4 are the faster processor (3 x faster) and 5 GHz wifi. There is no interference with 5GHz so you get better performance and as the range isn't as wide you dont have to share the bandwidth with neighbours etc. the hub still has 2.4 GHz so you still have the range you have withhub 3 too!
7:24
Dave:
Hi Winston, I am afraid there's no simple answer as it really depends on what features are in use. But the Hub 4 meets the latest Broadband Equipment Energy Code of Conduct targets for energy consumption.
7:25
[Comment From Mel Mel : ]
Why did you ignore your existing customers loyalty by charging them for a new hub, don't they pay enough already in their monthly fees?

Emma:
Hi Jade, thats something we are working on so yes something for the future
7:30
Sam:
Hi George. With regards to the manual power save feature, we have looked to make this automatic for all of our customers. However, you are able to change the brightness of the lights as an additional step.
7:30
Dave:
Hi Mel - we've made a lot of changes for our existing customers since the launch of the Hub 3 a couple of years ago. Our customer offer for the Hub 4 only £35 - a really big discount compared to the full price of £109! We've also created a range of recontracting deals that contain a Hub 4 for only the cost of delivery. If you're out of contract or in the last 3 months, you could take advantage of those offers as well. We really want all of our customers to be able to take advantage of these options!
7:31
Sean Donnelly:
Did you know the Hub 4 has a faster processor? Inside the BT Home Hub 4 router is our latest Broadband processor – the brains of your Hub. It allows you to pass information between connected devices quicker than ever. So if you are transferring files from one computer to another or watching a film streamed from another device, the BT Home Hub 4 won't slow you down.
7:31
[Comment From thebennyboy thebennyboy : ]
Our house has very thick stone walls and the wireless is weak in certain rooms. We have a few devices in our house that support 5Ghz Wi-Fi. Does the HH4 also work ok with home plugs that use your power cables to provide network connectivity?

yeah I can tell, I know your quesitons are pretty good but if you notice that JacquiBT is deliberately choosing the questions she wants to go through. The whole chat is based around the fact that they have added 5ghz. I am appauled as I was hoping to at least ask one question. -
Ask the Expert: Single-Site and Multisite FlexPod Infrastructure
With Haseeb Niazi and Chris O'Brien
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Single-Site and Multisite FlexPod Infrastructure with experts Haseeb Niazi and Chris O'Brien.
This is a continuation of the live webcast.
FlexPod is a predesigned and prevalidated base data center configuration built on Cisco Unified Computing System, Cisco Nexus data center switches, NetApp FAS storage components, and a number of software infrastructure options supporting a range of IT initiatives. FlexPod is the result of deep technology collaboration between Cisco and NetApp, leading to the creation of an integrated, tested, and validated data center platform that has been thoroughly documented in a best practices design guide. In many cases, the availability of Cisco Validated Design guides has reduced the time to deployment of mission-critical applications by 30 percent.
The FlexPod portfolio includes a number of validated design options that can be deployed in a single site to support both physical and virtual workloads or across metro sites for supporting high availability and disaster avoidance. This session covers various design options available to customers and partners, including the latest MetroCluster FlexPod design to support a VMware Metro Storage Cluster (vMSC) configuration.
Haseeb Niazi is a technical marketing engineer in the Data Center Group specializing in security and data center technologies. His areas of expertise also include VPN and security, the Cisco Nexus product line, and FlexPod. Prior to joining the Data Center Group, he worked as a technical leader in the Solution Development Unit and as a solutions architect in Advanced Services. Haseeb holds a master of science degree in computer engineering from the University of Southern California. He’s CCIE certified (number 7848) and has 14 years of industry experience.
Chris O'Brien is a technical marketing manager with Cisco’s Computing Systems Product Group. He is currently focused on developing infrastructure best practices and solutions that are designed, tested, and documented to facilitate and improve customer deployments. Previously, O'Brien was an application developer and has worked in the IT industry for more than 20 years.
Remember to use the rating system to let Haseeb and Chris know if you have received an adequate response.
Because of the volume expected during this event, Haseeb and Chris might not be able to answer every question.

Single-Site and Multisite FlexPod Infrastructure: FAQ from live webcast
Single-Site and Multisite FlexPod Infrastructure - Video from live webcastI would suggest you read this white paper which details the pros and cons of direct connect storage.
http://www.cisco.com/en/US/partner/prod/collateral/ps10265/ps10276/whitepaper_c11-702584.html This paper captures all the major design points for Ethernet and FC protocols.
I would only add that in FlexPod we are trying to create a highly available solution and "flexible" solution; Nexus switching helps us deliver on both with vPC and unified ports.
NPV equats to end-host mode which allows the system to present all of the servers as N ports to the external fabric. In this mode, the vHBAs are pinned to the egress interfaces of the fabric interconnects. This pinning removes the potential of loops in the SAN fabric. Host based multipathing of the vHBAs account for potential uplink failures. The NPV mode (end-host mode) simplifies the attachment of UCS into the SAN fabric and that is why it is in NPV mode by default.
So for your last question, I will have to put my Product Manager hat on so bear with me. First off there is no drawback to enabling the NPIV feature (none that I am aware of) the Nexus 5000 platform simply offers you a choice to design and support multiple FC initiators (N-Ports) per F-Port via NPIV. This allows for the integration of the FI end-host mode described above. I imagine being a unfied access layer switch, the Nexus team enabled standard Fibre Channel switching capability and features first. The implementatin of NPIV is a customer choice based on their specific access layer requirements.
