Voice VLANs with Multiple IP Phone Systems

We currently have a legacy TDM ACD system used by the Call Centre running alongside CUCM 8.5 which is used by back office and admin staff.
When we implemented the Call Manager we configured all our access ports with the Voice VLAN to make any office moves and changes straight forward, regardless of whether or not the position would have a Cisco phone i.e. a cisco phone could be plugged into any floor port throughout the building and it would register.
Currently I am in the planning stages of replacing the legacy ACD system with Avaya Aura which will be running side by side with CUCM. My concern is that every time there are office moves, the access ports are going to have to be reconfigured to the Voice VLAN of the relevant system depending on which type of phone is at that desk.
Has anyone had similar experiences and found a solution?
Not ideal I presume, but was wondering if we could use the same Voice VLAN for both systems?

It's just a VLAN. Don't sweat it, stick them all in the same one. Nothing will explode.
Each phone system will have it's own way of locating the call processor.
CUCM = DHCP Option 150
Mitel = Some other DHCP option (128-130, and some others)
Avaya = DHCP option 176
etc...
So you can set all these on your scope, and each phone type will find it's server...

Voice VLAN with SRW224G4P

Hi all,
I have been trying to config a voice vlan into this switchs for the last 3 hours and for me this is impossible... I know how to do in a IOS switch but with this switchs is a nightmare...
I have this topology,

The first 3 octes of the mac of my phone is inserted into Telephony OUI Table
The Auto Voice VLAN Membership is enabled in the port where phone is attached.
The port that is conected to SWCORE has the vlan 100 configured as tagged.
SWCORE has created the VLAN 100 and enabled as VOICE VLAN
The port that is conected to SW1 has the vlan 100 configured as tagged.
The port that is conected to router CME has the vlan 100 configured as tagged.
If I config other port into SWCORE with VLAN 100 tagged I can ping from CME to that host.
Could be the problem a vlan propagation error?
Somebody could help me? I am desperate...
Thank you in advance.

Hi David,
Thank you for the purchase of the switch.
.Like anything, even riding a bike, the switch is actually very easy to configure, if you have a little bit of practice on it..
You mentioned you are using the " Telephony OUI Table" i guess you have a SF300-24P or ordering p/n SRW224G4P-K9-NA. Please be specific with the switch models you are using.
Are you using the older SRW series or the refreshed SRWxxx-K9 (300 series) switch in the core?
Firstly, make sure you are using version 1.1.0.73 of the switch firmware. Do that change now or verify that 1.1.0.73 is the active image on the switch.
The switch has two areas for storing firmware images. It stores the new firmware in the unused image area. Check the administration guide for how to upgrade firmware and select new firmware for the next reboot.
CDP is enabled on the switch when you use the new software, it was not there with older firmware, hence my insistance at upgrading firmware.
( Personally i would prefer you to have a catalyst switch for your ISRG2 CME application, for tech support purposes. But this is the land of the free..)
I found the following when I added my SG300-28P to a VLAN aware UC500.
The UC500 was advertising vlan100 as a voice vlan, configured that by Cisco Configuration Assistant, you might try CCP on your ISR.
I had a IP phone plugged into switch port G7 and a uplink to my UC500 via port Gig27.
The following in blue is a screen copy from my 300 series switch CLI interface.
You will note the switch automatically populated both VLAN and port information, the only command I added was "no passwords complexity enable," and some usernames, which removed from the screen capture below.
the switch basically configured itself.

Switch automatically figures which ports should be tagged into VLAN 100.
I did not tell the switch it was connected to VLAN100. I did not add vlan100 to the VLAN database.
So get the ISR router to advertise VLAN100 as a voice vlan.

Voice VLAN with Nortel

I am using 3750 stacks in the access closet with the floor VLANs routed through a 4500. I am trying to determine the best way to get the Nortel IP phone to attach to the voice VLAN and have the internal port default to whatever the floor VLAN is. I am using Microsoft DHCP and I will not initialy trust the port but use a policy to set the trusts. Does anyone use Nortel and what do you believe is the best way to set this? Are there any documents anyone may be aware of to lead me in the right direction?
Thanks

Take a look at the following post.

51 APs on voice vlan with 110 802.11 Handsets and 300 VoIP handsets?

There are 51 APs with 110 Symbol 802.11 voip handsets, along with 400+ Mitel VoIP Handsets on one vlan..using mask 255.255.240.0 should I be asking if this is excessive multicast traffic ?
Anyone used the IAPP with Aeronet? Any drawbacks, feedback? Should the APs/802.11 VoIP Phones be on their own vlan rather than the voice vlan?

Jason,
Let me answer your question with another question - RTP streams from your phones would be unicast, unless you were using applications like multicast paging or multicast MOH. Are there any of these applications present?
For seamless roaming, you will want the APs to be located on the same VLAN and use the same SSIDs and addressing scheme across your wireless infrastructure. You could separate it from your voice VLAN for segmentation purposes, so long as DHCP services and QoS is present on your APs and distribution switches on the wireless VLAN.
A quick estimation of the traffic involved is 7.04Mb/s if every phone was being used simultaneously with a G.711 codec. Bandwidth would generally not be an issue, but latency and jitter are your priorities. Depending on how your wireless network is laid out, you shouldn't have more then 8-12 phones associated to a single AP or jitter, latency and retransmissions will become an issue.
Hope this helps.

Just got the Iphone 6 and it paired BT with the car phone system okay. But it will not pair with the audio part where I could play my recorded music with my 5-C. The system will not connect with the phone and the message is that the settings

My toyota Seinna 2011 refuses to connect with my Iphone 6 as a "portable player". Message says for me to adjust the player. On the phone it is searching for other devices but not connecting. Now same phone is paired with the car multimedia system and will take and make calls. Help!

I very much doubt it if you consider how much data Apple release to App developers
to allow them to create apps that work under iOS
Audi being lazy like most of the other motor manufacturers
They will be registered developers and as such get all the info and data they need

I've got a problem with dynamic vlans. Trying to figure out configuration for the topology similar to the one in the picture.
I’ve got four vlans for PCs, one vlan per department. I have to add fifth vlan (50) for devices that can be connected to any of the three switches: A, B, C. these devices need to be on their own vlan, no matter to which switch they are connected to. On the other hand, PCs connected to any port on those switches should be assigned to appropriate vlan (10,20,30 or 40).
I was thinking about using dynamic vlans with list of mac addresses of devices that need to be on vlan 50 but not sure what to do with PCs. I don’t think I can use fallback vlan as I can set up only one fallback vlan for whole network and not per switch or port.
I cannot use list of mac addresses of all pcs as there’s simply too many of them (my network is way bigger than in the picture, I simplified it only to present the idea). I imagine I would need multiple fallback vlans for different switches.
Has anyone got any idea that could help me please? Maybe there’s some other and easier way?

In new software (for Cisco switches) we provide multiple fallbacks for MAC authentication (MAB):
1. 802.1x
2. web authentication
3. guest vlan (if no supplicant on the PC)
4. auth fail vlan (if radius denies you access)
So you could keep a list of MAC addresses for vlan 50 and do MAB for these devices if MAB fails you can use 802.1x for your PCs.
This will require configuring 802.1x supplicants on all PC (Windows comes preloaded with one) and maintaining a radius of users who are able to log into the network. A lot of people use their Active directory pre-existing database as a backend to store their usernames and passwords for user authentication with dot1x.
With using both dot1x and MAB you can now distinguish easily between two different processes and use your radius server to assign vlans based upon almost anything you can think of.

OTV site vlan with multiple overlay interface

Hi,
I have an OTV multihoming sites. 2 sites. 2 otv edge device each site.
and with multiple overlay interface sharing 1 joint interface
otv edge device connected to multiple VDC.
each internal / downlink will forward different vlan for each vdc.
================================
example
int overlay 1
otv extends-vlan 10
int overlay 2
otv extends vlan 20
int eth 2/1
description trunk to VDC1
switchport trunk allowed vlan 10,100
int eth 2/2
description trunk to VDC2
switchport trunk allowed vlan 20,100
otv site-vlan 100
================================
i understand that i can only use 1 site vlan.
so in order for the failover to happen, both eth 2/1 and eth2/2 must fail?
what if only int eth2/1 fail? will the int overlay 1 failover to secondary otv device?
thanks,
ivan

"So when querying the adjacency server the ED then knows which other ED is within the same site?"
Yes for the first part of the question, using the site Vlan unique to each site.
Why do you need a routed link between ED's at local site? You dont need to connect those back-back over L3. Moreover if you want to use it for L3 ADJ over peer-link, you need to make sure that VLAN that you are using is not allowed on the VPC member ports, just on the peer-link, else VPC loop alrorithm will break your traffic.
Are you planning to use multicast or a Unicast deployment? I remember I tried testing the topology in a POC for one of my customer, things did not work as expected in multicast deployment mode and worked fine in Unicast Adjacency server mode. I need to go back and check my notes on this.
I would rather have the join-interface go back to a routed core at site rather than back-back connecivity as it opens up the tested Multicast deployment mode.

When closing 2 windows(with multiple tabs each), system restore does not properly restore the second window's tabs. Is this a bug in the new update/any ideas to fix?

I regularly use 2 windows with multiple tabs each and session restore would work to get them all back, but after this latest update the second window does not restore properly, with the first tab not visible on top(only in drop down menu) and the add a tab button now on the left(instead of right). The add a tab button is not really concerning other than it indicates other problems with the tabs on tab of the 2nd window. Not having the 1st tab visible is frustrating, because I can not move it or as easily navigate. Also, the tabs on top of the 2nd window that are visible no longer have the "x" to close visible unless that tab is selected. I'm assuming this is a problem with the new release/update, since this is the first time I've ever encountered the problem, and I've shut down and restored Firefox a few times to make sure this was a recurring problem and not a one-time deal. Any ideas on how to fix would be welcome(other than perhaps cramming my tabs onto one window or sucking it up XD).

JMS to communicate with multiple 3rd party systems

Hi,
I'm fairly new to JMS and I need to build a system where I communicate with several third party systems through JMS.
Basically what I need is some sort of synchronous message system, as I need the result to display on my webpage.
In this scenario, I was wondering what is the most common design here, in terms of queues or topics.
Would it be normal for each system to have a input and output queue, or is it more practical that I provide a outbound topic and an inbouw queue that these systems could use?
I know how I can set this up, but I just wanted to ask if it is normal practice to ask a third party to connect to your own JMS system, rather than connecting to their queue/topic?
Thanks,
Steven

CIF blocks with multiple R/3 systems

Hi,
We are in SCM V5 and we have two R/3 systems connected to one APO system. Theya re two different BSGs, with totally different integration models as well.
We are using APO outbound queues for both the R/3 systems.
The question is, does a CIF block from one R/3 system block the order from other R/3 system?
Example:
I have a planned order PO1 created in APO that is bound to go to R/3 system R1. This order is now stuck in SMQ1 in APO.
I create another planned order PO2 that is bound to go to other R/3 system R2 from the same APO system.
Does the PO1 block PO2?? or are they separate?
I would appreciate if you can substantiate that with some reference.
Thanks.
Edited by: Raj G on Nov 5, 2008 8:24 AM

I have not seen such a configuration myself offlate, but based on theoretical knowledge one outbound queue block to one R3 system should not interfere with another outbound queue to another R3 system. The queues are RFC destination specific. INtegration models are also specific to a destination R3 system. However there may be elements that are common - mostly BASIS level settings. Not sure if it interferes with the application.

Multiple vLans with Multiple Gateways

HI.
Got a SF500 in layer3 mode, operating 5 vlans all with their own subnet.
Vlan 10 = 192.168.10.0/24
Vlan 100 = 192.168.100.0/24
Vlan 200 = 192.168.200.0/24
Vlan 201 = 192.168.201.0/24
Vlan 202 = 192.168.202.0/24
We have a gateway on Vlan 10 (192.168.10.1), which all vlans can see & access (because of intervlan routing), and this at present allows vlan 10 to access the internet.
I want vlan 100 to be able to access the internet through this gateway as well, although the other vlans (200,201,202), will use a different gateway located on vlan 200 subnet.
Of course, the gateway has to exist in the subnet. I cannot assign the default gateway of a machine on vlan 100, an ip address of the gateway on vlan 10.
If I point the default gateway to the virtual interface in its subnet (e.g. 192.168.100.254), it equally does not know how to get out to the internet, even though it can see the gateway (I can access a web page it hosts).
So the question is this:
Can vlan 100 traffic be routed on the SF500 to use the gateway on vlan 10? (outside of the default gateway of the switch).
If this is not possible with the SF500, what would I need to make it work?
Many thanks.

Hi Andrew,
I don't have more information about your network so I will try to much your configuration from your post
let's say we have this configuration :
1. Create Vlan 10 and assign on SVI IP address 192.168.10.254 /24
2. Create Vlan 100 and assign on SVI ip address 192.168.100.254/24
3. Create Vlan 200 and assign on SVI ip address 192.168.200.254/24
4. Create Vlan 201 and assign on SVI IP address 192.168.201.254/24
5. Create Vlan 202 and assign on SVI IP address 192.168.202.254/24
and the gateway (Router) is on Vlan 10 with IP address 192.168.10.1
6. we assign at least one port to each vlan and the switch port from where is connected to the router should be trunk (10U,100T,200T,201T,202T) it means All the traffic from Vlan 100,200,201,202 is Tagged and transmitting through Untagged Vlan 10
7. Under IP Cofiguration --> IPv4 Management and Interface --> IPv4 Route
8. add the deafult static route to the gateway :
Destination : 0.0.0.0
SubnetMask : 0.0.0.0
Remote IP GW :192.168.10.1
Now from the router expectation : router need to NAT all the source IP address (200.0/24 , 100.0/24 ...)
I don't know what the router you have but there is a router where NAT all the source coming to him to go to Internet, but there is other router which need to configure NAT for the unknown address for the router side --> Here is up to the Router
after that connect PC to port on Vlan 100 setup static IP for example 192.168.100.100/24 with Gw 192.168.100.254 should access to the internet via the trunk port on the switch and router should NAT this subnet to go outside
Hope I was clear
Please rate this post or marked as answered to help other Cisco Routers

Multiple Vlans with multiple Internet connections using PBR

Hello all,
I'm trying to wrap my head around this configuration and not having a lot of success. I have several Vlans 3,6,71,72,160, and 180. I have two internet connections, Internet1 is connected to an ASA5510 and Internet2 is connected to a Meraki MX80. I'm using two 4506 switches on my backbone trunked to 3750 switches that my clients connect to. None of these switches have IP Services and my 4506 supervisor does not have an Enterprise license. However I do have one 3750 100Mbit switch with IP Services so I'm using that to do my PBR. All my routing is currently being done on the 4506 switches and all Internet traffic is going to the ASA. What I would like to do is force vlan160 and vlan180 through the Meraki as their Internet connection and the rest of the Vlans go through the ASA. I'm thinking about trunking my vlans from the 4506 to the 3750 (the one with IP Services) and use policy based routing from there to force vlan160 and vlan180 to the Meraki. But in order to do this I think I would have to move my routing onto the 3750 switch but since that is only 100Mbits I'm thinking this is going to choke my network down and defeat the purpose of the 4506 backbones. Any suggestions or alternate ways to achieve my goal?
Appreciate any help you guys can send my way.
Matt

Matthew
What is the speed of the connection from the 4500 to the ASA and what is the combined speeds of the internet connections ?
You definitely don't want to do all the inter vlan routing on the 3750. You could connect it up as shown in your diagram but leave all the routing between vlans on the 4500s. Then you -
1) connect the 3750 to the 4500 using a L3 point to point link
2) connect the 3750 to the ASA using a L3 point to point link
3) do PBR on the 3750 interface connected to the 4500 for traffic coming from the 4500.
If the 4500 supervisor/IOS version doesn't support routed links on that end just use an access port in a dedicated vlan ie. no other ports in the vlan and create a new SVI for it.
You would need to update your routing to reflect the next hop on the ASA, Meraki, 3750 and the 4500.
Disadvantages are -
1) you only have fast ethernet ports on the 3750 so if the combined internet speed is greater than that then it will be a bottleneck.
2) it is a single point of failure ie. if it is lost all internet via both connections is lost.
The alternative would be to not have the 3750 in the path but connected to the 4500 via a trunk link and then route just vlan 160 and 180 on the 3750 ie. move their SVI(s) onto the 3750. Then the 3750 could have a direct connection to the Meraki device and point the default route that way (no PBR needed). The trunk would only allow those specific vlans on it. This would mean a failure of the 3750 would not mean ASA internet lost but it would mean loss of connectivity for the two vlans routed on the 3750.
You would need to add routes to the Meraki for return traffic plus routes on the 3750 and 4500 for inter vlan routing.
The main disadvantages here are -
1) inter vlan routing between the vlans routed on the 4500s and the vlans on the 3750 will be limited by the 100Mbps connection. However you could use an etherchannel trunk so you could get greater overall throughput and some redundancy
2) more importantly though i suspect you are running HSRP between the 4500s for the client vlans and moving the SVIs onto the 3750 means a single point of failure for those vlans.
Personally i would tend towwards option 1) because of the SVI HSRP issue and perhaps because there may be a lot of inter vlan traffic and even with an etherchannel it would be too much.
But, single point of failure issues aside, a lot does depend on internet bandwidth in option 1) vs inter vlan traffic in option 2).
So it's a tradeoff and personally i don't think either are ideal so i'll have another think on this in the morning to see if there is anything more obvious that i have missed or maybe someone else will add to the post.

Multiple vlan with multiple SSID

I have a 1130 AP connected to a 500 series express catalyst switch. I want to have two vlans one for guest internet access only and the other that can have both internet and internal access. I want to have two SSID one for guest and the other for internal employee which should match the vlan. Can anyone guide me to a good doc. that can help me implement this solution. And is the 500 series switch is capable of doing this.
Thanks.

To anwser your first question Yes your 500 series switch is capable of doing vlans (See Link: "http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6545/product_data_sheet0900aecd80322aeb.html") (first time pasting a link sorry if it doesnt work) here is another link that you can utilize on config examples. and as for you access point you can do the same as well (http://cisco.com/en/US/products/ps6087/tsd_products_support_configure.html)
