Stackable switche options with Nexus range? - Nexus 3172
Hi all,
We are looking at upgrading our Rack switches. We have 3 racks and need about 80 10Gig copper/RJ45 server ports per rack. We are fairly price conscious.
I am new to Nexus product range, but have a lot of experience with Catalyst switches.
We are considering Nexus 3172T switches. But I’m not sure if they are really suitable because they don’t stack.
I would far rather a switch model that we can stack together so I don’t need to manage each switch individually (much as you would do with Catalyst 3750). We did look at Catalyst 4500X but they are too expensive.
Initially we only need Layer2 switches, but I would really prefer stackable switches in case we move to Layer3 switches (I don’t want to have to muck around with HSRP).
It really seems to be a big hole in the Cisco product range. Every other vendor we have looked at has a Virtual Chassis (Juniper, HP, Brocade) system that would be idea. Cisco have VSS in the 4500x but its pretty rubbish as it only allows two switches.
What sort of options do I have with Cisco Nexus at a reasonable price?
Simon
I 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.

Dell Servers with Nexus 7000 + Nexus 2000 extenders
<< Original post by smunzani. Answered by Robert. Moving from Document section to Discussions>>
Team,
I would like to use some of the existing Dell Servers for new network design of Nexus 7000 + Nexus 2000 extenders. What are my options for FEC to the hosts? All references of M81KR I found on CCO are related to UCS product only.
What's best option for following setup?
N7K(Aggregation Layer) -- N2K(Extenders) -- Dell servers
Need 10G to the servers due to dense population of the VMs. The customer is not up for dumping recently purchased dell boxes in favor of UCS. Customer VMware license is Enterprise Edition.
Thanks in advance.To answer your question, the M81KR-VIC is a Mezz card for UCS blades only. For Cisco rack there is a PCIe version which is called the P81. These are both made for Cisco servers only due to the integration with server management and virtual interface functionality.

Peculiar Timing Issue With PxE In Nexus Environment
I have seen some peculiar behavior doing PxE builds. I wanted to pick the brain of some experienced network engineers as my research on the internet shows there is a ton of contradictory opinions / philosophies.
Here is the setup:
1. HP SL4540 Servers with a Broadcom Copper/RJ-45 10Gbe Cards with PxE enabled.
2. Connected to Nexus 2232 10G Copper/RJ-45 edge switches going back to a Nexus 5596 aggregation layer.
3. IP helpers services are enabled on the 2232 so that DHCP and PxE requests are forwarded to a specific IP address.
4. Both the Switch Port & NIC Port are set to auto-negotiate.
Problem:
With the solution fully configured, the servers still fail to either find the DHCP / PxE server or make initial contact but never complete the handshake process. The peculiar thing is that we sometimes will see this late at night. We break for sleep and wake up in the morning and the servers are fine and ready to load an OS. There is some type timing phenomenon going on in the background and given enough time they eventually find this timing window and move forward.
I’ve read dozens of articles now and I have found some experts pointing to potential causes but then others refuting the same ones. Here are the preliminary ones I found.
1. With NIC and Switch Port set to auto-negotiate the negotiation process is taking longer than the PxE request process cycle which seems to be pretty short (10 to 15 seconds). I have read tons of conflicting info. Some of it (Citrix, Altiris, VMWare) saying setting to full duplex will circumvent the negotiation process if it is indeed taking longer than the PxE request process. Other docs say Gigabit Ethernet requires auto-negotiate and wont work without it. What are your thoughts on this ? Is Auto-Negotiate absolutely required for 1G/10G and if not can setting to full duplex potentially help the NIC sync with the switch quicker ? We do have tight control of server and switch so can ensure both are set to whatever we need.
2. I found a bunch of articles where PxE fails when certain services are active on the switch. The articles showed that these services can cause a long negotiation process to get link, or even allow link but hold packets for a bit as they bring in the new connections. The ones in particular they mentioned were:
a. Spanning Tree Protocol
b. Ether Channel
c. Port Aggregation Protocol
d. Disabled PortFast Service
What are your thoughts on this ? Are there other services that could have a similar effect ?
3. Outside these theories any other reasons one could see why this would happen ? The fact that it eventually “fixes itself” bugs me so I want to find a definitive answer.
Also from the switch side what troubleshooting steps can we take to prove or disprove these theories ? We can pull the switch logs, is there any other things to look for or monitor ? What would we expect to see in the switch log if one of these theories were correct ? Would loading WireShark and examining packet dumps be of any use here ? Any insight would be greatly appreciated.

I created a playlist with 100 songs. I want those 100 songs played using the shuffle option. This no longer works in iTunes version 11.1.5.5 How can I get an entire playlist to paly one song after another by using the switch option?
You're welcome.
Going back to your original post:
5) Tried running Itunes in 'safe mode', running itunes as an administrator..nothing.
Was that iTunes' safe mode as opposed to Windows' safe mode? iTunes safe mode is invoked by holding down CTRL+SHIFT immediately after clicking the icon to launch iTunes and continuing to hold until this message pops up:
Click continue, then close iTunes and reopen. With luck iTunes now opens normally every time.

Problems with the Galaxy Nexus
I upgraded to the Galaxy Nexus – your flagship device. It now has a whole laundry list of known, critical issues. You’re holding the Android software update that will fix these known problems but you won’t release it. After 5 months, still no fix. Even while the Sprint Galaxy Nexus has Android 4.0.4, we're stuck on the the buggy 4.0.2.
Now that you have me locked in a contract the only thing you’ll do is replace my phone with the same model that’s refurbished – not even a new phone of the same model. And it would come with the same software version. You won’t even replace my phone with a different model that works as expected. I’m just one of many, many people in this situation. Let’s see where JD Power and Associates ranks your customer service next time, Verizon Wireless. Shame on you! Even your own forums are filled with complaints from Nexus owners and still VZW remains silent. This is **** poor customer service and it has definitely been noted by me and many others.Now that 4.0.4 is slowly being released, I'm yet to hear anyone say that the intermittent muting problem, the random resets, or any of the other problems have actually been fixed. I found an app that helped with the 3G dropping problem, but that was on the last phone, and I don't remember the name. I'm sure it is in the My Apps section somewhere. Not going to bother since I'm going to ask for another replacement phone soon.
I was told by a rep that I had to receive three phones before Verizon would give me a different model. I'm on number 3, but their records only show 2 replacement phones. I guess the one I got 3 days from original purchase didn't count 'cause I got it from the store and not through customer service.
Anyway I'd like to see a list of the bugs/problems that 4.0.4 actually fixes. What I've seen is a list of new problems.
My biggest frustration is that verizon doesn't/won't even admit they have a problem. If they would just give the reps a line or two about the problems and send us to tier 2 or 3, it would be different, but tier 1 wants to try everything on their list of fixes before they will let us talk to a tech that at least knows there is a problem, however won't say so directly. I'm fed up with Verizon and it's time to do something. I'm looking at the other 4GLTE verizon phones and they seem to have problems too. I'm not an apple fan so there really isn't anything that Verizon has that I want to downgrade to, except maybe a phone that I don't use and just pay the base for the remainder of the contract.
I hate liars and by withholding the truth, it makes Verizon Wireless reps look like liars.
ok I've said too much, but seems like a good place to rant for a while. Thanks for listening. -

I am trying to switch laptops with my mom, and successfully wiped mine and restored it, but now the password that she used on her computer isn't working on this computer. Is there any logical reason why the two passwords would be different, if I restored her information from a Time Machine backup? Aditionally, Is there a way to bypass the password page on startup to make a password that my mom knows?
If Disk Warrior does not work you can try the following steps (but they may not work if the disk has a hardware error).
Get the disk (DVD or CD) that came with the system (since you have it listed as 10.6.8). If it is 10.7 or 10.8 use the Recovery partition to boot from or the USB installer if you have that option.
Insert the disk then power down
HOLDING the C key, power up to boot from the disc.
Get to Disk Utility
If Disk Utility will now show your hard drive, use DU to REPAIR the disk.
When it completes the Repair process successfully as indicated in DU, do a shut down. If Repair is not successful then an different course of action is indicated below.
Then HOLDING THE APPLE (or Command key depending on your keyboard) KEY AND THE OPTION KEY AND THE LETTER P AND R KEYS, continue hiolding them until you hear the chime tone for the THIRD time then release all four keys.
If REPAIR is not successful, use the Install disc as a boot and REINSTALL THE OS X OPERATING SYSTEM DO NOT ERASE THE DISK OR VOLUME FIRST. REPEAT DO NOT erase the disk or volume before trying to reinstall the OS X operating system. After re-installing the OS do a software update. Note that ERASING the disk is NOT required to do an OS re-install. This allows your existing data and application files to remain.
If that fails then you are down to the "bitter end" of erasing the volume and reinstalling the OS and then all the other software.
If erasing the Volume fails then your last hope is to completely erase the entire hard drive, repartion the disk and try a re-install.
If that fasils then you may have a defective hard disk. -
Can no longer simultaneously stream an mp3 in Safari when using fast user switching option.
After updating to ios 5, I can no longer stream an mp3 in Safari when I use the fast user switching option. For instance, if you are listening to streaming content in a Safari tab and want to reference another app as soon as you switch from the Safari stream pauses.
This was not the case with previous versions of ios. Any ideas on a work around to restore this functionality to keep Safarr streaming content in the background?User switching problems is the very first thing I noticed with SL. I have a host of other problems with SL but this is one of the most frustrating. The user switching did not work on 10.6 very well either but was wicked fast in 10.5.x
Apple rewrote the Kernel so this type of thing is expected, still the test crew missed this very noticable problem. Hopefully 10.6.2 has a fix. -
CS6 Mixing Down Sesx With Marker Ranges Past The Last Clip
This does have a little to do with a previous thread (http://forums.adobe.com/message/4440234), but is specific enough to not add to that thread.
I just noticed some strange behaviour (and erroring) in CS6.
I have a sesx with 5 minute marker ranges from 00:00:00 to 02:30:00 (30 marker ranges).
Let's say a clip (or group of clips) is only 01:05:23.
If you do Mixdown To New File - Entire Session, the resultant mixdown will be 01:05:23 (as you would expect), but it will have all 30 marker ranges (extending past the end of the timeline).
If you select marker ranges 1-14 (14 is where 01:05:23 falls within) and export selected markers to files, you will get a 23 second file as the 14th file.
On the other hand, if you include marker 15 in the selection (or select all, for that matter), you will get an error for every range that it tries to export that doesn't have audio.
If you do a time selection, in multitrack, and Mixdown To New File - Time Selection, the extra marker ranges do not get included in the mixdown.
JJ
Edit...
A bit of background as to why we are using the session this way...
We use Audition, mostly, for editing sermons preached at our church that are to be produced for cd.
The audio is recorded in as a mono file (directly from the microphone channel), is edited in mono, and stored in mono (stereo takes twice the hard drive space and is an unnecessary conversion for a mono signal).
These sermons are, generally, parts of a series that will be available as a series (as opposed to individual sermons).
Once all the individual parts of the series are edited, they are imported into a session for that series (based on the afore-mentioned template with 30 marker ranges).
Part 1 is track 1, part 2 is track 2, etc... (all sermons start at 00:00:00).
In this fashion, it's easy to see which sermons are longer than 01:19:58 (IE...go to 2 cds) and we can use volume envelopes for the fade out of cd1, fade in of cd2, and whatever we want to overlap between the 2 cds.
Track 1 might be 01:26:32, track 4 might be 00:48:22, track 13 might be 01:15:01, etc... (02:30:00 was chosen as the ending time as we've had 2 sermons longer than 02:20:00 but none longer than 02:30:00).
In AA1.0 and AA1.5, there was a simple option to right-click on a clip and Mixdown To New File - Selected Clip that was removed in AA2.0 (I think) and hasn't made its way back since (I plan to submit a feature request for this).
The biggest reason why we use multitrack for this is that the mixdown will automatically convert the mono file to stereo and transfer the marker ranges from multitrack to the resultant mixdown.
Yes, we could just manually convert the mono file to stereo and add marker ranges.
That is a lot of unnecessary work, though, when it happens in the mixdown.
AA1.0 and AA1.5 worked perfectly, for this function, as it had the ability to mixdown selected clips.
The resultant mixdown would be an exact duplicate of the clip, in stereo, and with marker ranges that were correct.
There may be some different functionality that hasn't been explored, but what I have found is we simply have to do more work to get the same result.
JJThanks. I don't see any error message, but I do find Audition locks up when attempting to export Marker ranges that don't have audio data associated with them. I'll write a bug and get it assigned this morning. While out-of-bounds markers are perfectly legitimate and have valid use cases, Audition should handle them more gracefully when asked to perform certain tasks.

ACE FTP inspect with port range
Hi everyone,
I have a problem with passive FTP with fixed port range.
I configured a ftp server with a fixed port range of 60000 - 60500 for the data channel.
And the ace is configured with "inspect ftp" on policy of ftp-serverfarm.
A tcpdump on server I can see that the server uses the portrange in response packet.
(x,x,x,x,34,195) = 60099
But on client I can see that the port on packet is change to another port. The ace is between server and client.
On CCO I found a document "http://www.ciscosystems.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA1_7_/command/reference/policy.html#wp1006925" ->> Enables FTP inspection. The ACE inspects FTP packets, translates the address and the port that are embedded in the payload, and opens up a secondary channel for data.
I don't understand why the ace change the port in ftp payload.
Is it possible to create the same port range on ace configuration of connectio to client?
Thanks
RenéYou don't need inspect ftp with one server because you can avoid it.
You can for example configure a loopback on the server with the vip address and configure the serverfarm as transparent on ACE.
Then for the data channel, since your range of ports is quite small, you can catch it with a class-map and simply forward to the server.
Like this, the server will use the vip address in all packets exchange with the cleint (no need to nat the payload) and when the client opens a data connection, the traffic is matched with the class-map and the connection can be forwarded to the server using the same transparent serverfarm.
Less chance to run into compatibility issue.
Better performance since we can switch traffic with inspecting its content.

Teaming options with Windows 2012 R2 Host for HV Guests
Hi
We are configuring Windows 2012 R2 standard host servers for Win 2008 / Win 2012 Guest servers. We have 3 NICs and using one for host management and other two in windows teaming. We read many blogs and supported configurations, but still not clear about
the options with teaming. Usually with teaming we select the default options such as Switch Independent Teaming mode, Dynamic Load Balancing mode with no standby adapter. Recently with this teaming configuration we faced issues with host servers on multiple
Windows 2012 R2 standard host servers (the guest hang multiple times) and when we removed one of the NICs from team it started working fine. With the switches we didn't find any issues nor with NICs. Is it because of the default team options? Should we go
with Hyper V port Load balancing mode?
Expect support from you guys. Thanks in advance
LMSLaljeev Madanamma
TCP Chimney is not supported with NIC teaming in Windows Server 2012 R2 since TCP Chimney has the entire networking stack offloaded to the NIC, please check you have disable
it.

WD: Select Options shows empty ranges
Hi there,
Im using select options in my wd application... I defined a few fields (numeric, dats and so on). I was expecting that the select options in wd works like the normal ones in normal abap report.
But when I try to read the results from select options , the result range table has no sign or option value (low value ok) ... when I reach the result to a Select statement a shortdump happen with the notice there is no sign or option value in the IN parameter of the Selection statement.

VFC is down Nexus 5020 Nexus 4001i
Hi All,
I am very new to Nexus 4001 and facing a problem related to its configuartion.
The topology involves IBM HS22 blade server with Qlogic dual port CNA, Nexus 4001, Nexus 5020, MDS 9513 and EMC storage.
I have done the configuration related to fip snooping in Nexus 4k and FCoE configurations in Nexus 5k.
The problem is that i am not able to get the enode mac address when i am running the command "show fip-snooping vlan-discovery".
also i am not able to make the vFC up in Nexus 5k.
I can upload the configuartions if needed.
Kindly suggest your comments or any solution.
FYI: All licenses are installed in Nexus 4k and 5k and FCoE and CNA drivers are installed in IBM server.
Thanks in advance,
SanjeevIf the show mac-address is not showing any src mac being learnt in native vlan indicates server is not sending FIP messages. The output you provided does confirm this theory, see the marked output in bold which has value of zero.:

Based on the output you provided it looks to be a CNA issue, the next step would be working with vendor to ensure Datacenter Bridging is working correctly. Do you have OS loaded on local disk or trying to boot from san? -
Why is the "show fast user switching" option grey?
My MacBook has only ever had one account on it until now. I noticed that the Fast User Switching option wasn't showing up in my menu bar, so I went to System Preferences > Accounts > Login Options to enable it. However, the option to "Show fast user switching menu" is grey and I cannot select the checkbox next to it. Yes, I am using an admin account and yes, I have clicked the lock to make changes in the Accounts preferences pane.
I have the same problem- I have three accounts on this machine.
The option is greyed out. I tried zapping PRAM, and restarts but no joy.
It coincided with a forced shut-down after an HP update installation hung all day on one of the accounts. "turning off may harm your computer"...
Any clues to a fix would be welcome.
Thanks. -
Why don't I have reduce motion option with iOS 7.0.2 upgrade?
Why don't I have reduce motion option with iOS 7.0.2 upgrade? It is making me really dizzy and sick to my stomach similar to reading in the car (can't do that either). I read to go into general settings, accessibility and click reduce motion....I do not have this option at all. HELP!
Seconded. Although my main problem w/ that zoom-out-as-app-loads effect is that I suspect it's the source of that annoying delay between app zooming open & UI being active/accepting input. When I switch between apps, after the zoom completes, there's 1-2 seconds where the app accepts no UI input at all. This seemed instantaneous in iOS 6.
(Oh, off-topic, but the control center is devilishly hard to sweep up. most of the time I accidentally start Safari or Mail.)
