Cisco voice vlans w/ nortel VOIP system

Hello everyone,
I am going to segment a network with a Nortel VOIP system. Right now, the network is completely flat with PCs plugged into the back of the nortel phones. I would like to set up a voice vlan for the nortel phones but am not sure if voice vlans will work w/ non-cisco phones (cdp). Please provide me some insight if you can. Thanks!

If your are Using Recent Cisco Switches it is quite easy.
Using 4006 SUP III core switches or 3560 PSE's should be okay.
If you have Nortel Phase II phones they can also be powered by the 802.3 cisco switches with no probs.
Anyway set the switchport mode to switchport voice vlan. Set spanning tree portfast and configure qos as you see fit on the port. Configure the voice vlan on the switch eg switchport voice vlan 111. You may need to configure the port to switchport mode dynamic desriable as well. Some older switches may have problems but you can enable trunking to cheat and then a default vlan for the pc on the switchport
As regards to the phones when the phone reboots and you enter the configuration mode via flipping the 4 soft keys. You should then see the vlan option and configure the same vlan number on the phone as the cisco switch eg 111.
The phone should then register again without any problems. All i2002/i2004 firmware for last 2 years has the vlan option. I looked after about 400 nortel phones all on cisco switches of various ages with only minor setting up issues.
Best of luck

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.

Voice VLAN config 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...

Cisco Layer 3, Voice, & VLAN

I have a vSphere 5.5 install and I'm in the process of a network upgrade in preparation for a VOIP implementation. The Switch hardware I'm using is a stack of Cisco 3850 Layer 3 switches and I've been going in circles on getting vlan traffic to work correctly. Hopefully someone can point me in the right direction.
I have one NIC connected to the switch (10GB fiber) that will handle all traffic for the esxi host (except for management). VLAN ID is set to None (0) and load balancing is set to Route based on originating virtual port.
I have 2 subnets, 10.1.0.0/16 (data & management, VLAN 1) and 10.10.1.0/24 (Voice, VLAN 10)
On the host I have a Win 2012 R2 server that will be a VOIP PBX host. It must be able to communicate with the IP phones (VLAN 10) and other servers (VLAN 1).
The switches will do the intervlan routing.
Finally my question - Can anyone give me some hints on how to set up the interface on the Cisco for the 10GB fiber connection from my host? Actual port settings would be extremely helpful. Anything I'm doing at the vmware end that I should be doing differently?

In case anyone comes across this in a search, here's what I ended up with, 1st the Cisco switch:
switchport trunk allowed vlan 1,10
switchport mode trunk
switchport nonegotiate
switchport voice vlan 10
macro description cisco-switch
spanning-tree portfast
spanning-tree link-type point-to-point
The virtual switch I set to all vlan IDs and Route based on originating virtual port.

Passing Voice VLAN through a non-Cisco switch

Hi All,
Will a non-Cisco switch (no 802.1q support) that is putted beetween Cisco IP Telephone and Cisco Catalyst switch (which is configured with auxilary Voice Vlan) pass voice vlan frames and CDP?

Any switch should pass on either ISL(which is cisco properitary and hence not supported on non-Cisco) or IEEE 802.1Q frames or else it cannot support voice vlan support . And non-Cisco switches do not support CDP as it is once again Cisco proprietary protocol.

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.

DHCP and voice vlan on Cisco 3560 switch

Greetings,
I'm setting up a Cisco 3560 switch for voice and data comms. I'm looking for documentation with best practice guidelines for the following requirements.
1. Using the Cisco 3560 as a DHCP server - Config examples. Do I need to use different subnets for the voice and data vlans?
2. Layer 2 CoS QoS - I'm connecting Aastra phones as well as notebooks - I've been told that Aastra also makes use of the voice vlan config through LLDP and that Aastra phones supports CDP.
Your assistance will be appreciated.

Hi ,
Cisco recommends that you have a separate vlan for voice and data with different ip subnets for voice and data. You will need to configure the dhcp pool accordingly.
Here is the config guide for setting up IOS DHCP server:

Here is the LAN qos recommendations:

Cisco sg200 voice vlan dhcp issue

i have cisco sg200 50p connected to cisco 3750 switch. i just wanted to separate voice (vlan2) and data (vlan1) VLANS. I created vlan 2 as my voice VLAN and separate dhcp server for vlan 2 to give ip addresses to phones. however the ip phone connected to my voice vlan (vlan 2) is not receiving ip address from my dhcp server in vlan 2.
the dhcp server is connected to 3750 switch with an access port (vlan2-voice)
two switches are connected via trunk ports and allowed vlan 1&2
ip phone is connected to sg200 via access port (vlan 2) -
note - there is no pc connected to ip phone
I really appreciate if anyone can help me with this issue

Hi Tom
Thank you for the support. The phone is now getting the IP from the DHCP on its own VLAN (vlan2 ) according to your configuration. However i need to configure the auto voice VLAN based on OUI feature which is in SG200 switch.
The problem is, the switch not allowed me to configure auto voice vlan feature when the port connected to IP phone is in ACCESS mode (it has to be a trunk). I know according to cisco catlyst guidelines this is totally incorrect bcz they say "Voice VLAN is only supported on access ports and not on trunk ports, even though the configuration is allowed"
I think its not valid for Small business switches . Anyway, when i make the said port TRUNK it works (by assigning 1U & 2T- automatically).But the phone does not get an IP address from my DHCP server then.
Can you help me with this if I am missing some configuration. Thank you once again

Help w/Voice VLAN on SMB 300-10p

We have purchased serveral new SMB 300 switches to support our VoIP rollout and save cost. I'm use to using the CLI on cisco devices, but now i'm stuck figuring out the GUI that comes with these switches.
I have setup the Voice VLAN to be 100, i have setup the port type as general, and i have added the port to VLAN 4 (data vlan). when i plug the NEC phone into the switchport and the computer into the phone, the computer gets an IP in VLAN 4 but the phone gets an IP from VLAN 1 not VLAN 100.
Like i said i set the Voice VLAN to 100, but when i look at the Macro for the smartport it is saying the voice vlan is 1. Do i have to manually change the macro somehow? can i change the macro somehow?
Sorry i don't have a lot of info in this post. If you need to know how anything else is configured just ask i'll post it up.
Thanks
Karl

Hi Karl,
You can use the serial db9 console cable that came with it for a hardwired connection (I use putty):
Also you can enable telnet and/or ssh: Status and Statistics -> System Summary, look for TCP/UDP services status and then hit Edit, enable what you want, hit apply, and remember to save the config. Also, you can go right to Security -> TCP/UDP services to enable:
Best,

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,

I have this config in my router,

SW1 has created the VLAN 100 and enabled as VOICE VLAN
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.

Setting up Cisco SLM248GT-NA switch for VoIP

Hello Everyone,
We have a Cisco slm248gt-na smart switch in our office that I am trying to configure to support and optimize for VoIP. We have desktops hooked up off the phones in most cases. Are there any config guidelines to optimize the switch so it has proper QOS set and VoIP gets higher priority over data.
Thanks, Kind Regards
Shabbir

Hello Tom,
Thanks for your reply.
We have a pretty straight forward setup. We have 15 Cisco SPA303 phones hooked up to switch and the desktop are connoted via the phone. We have a wireless LAN and a corporate server that servers as a file sharing/vpn type setup. Other than that there are no devices hooked up. We had to implement auto voice vlan feature but were still running into issues like occasional poor voice quality and one way audio type issues. However I did notice something in the configuration menu "Telephone OUI", could you please help us on how to implement that. We are trying to implement best practice to avoid voip related issues that we have been having.
We also see all the ports in trunk mode. Is that the recommended setting or should we change it to access mode?
Thanks, Kind Regards

Inter-VLAN routing, Auto-Voice VLAN and IP Address-Helper

Hope that somebody can help me with the setup in the screenshot.
Planning to use Auto-Voice VLAN and Smartports to configure VOIP
LLDP-MED will be enabled on the switch to detect the IP phones so they will be moved to the Voice VLAN (If not the first 6 signs will be added to the OID table). The Voice VLAN ID will be 2 >> Voice VLAN will be automatically enabled once a device is recognized as a IP phone right?
Workstations will be connected to the Cisco switch, VLAN data will be untagged and will remain on the native VLAN.
Smartports will be used to configure the ports (Macro's) >> Should configure the ports as trunks as assigns the correct VLANs right?
But how do i configure the IP Helper-Address? Do i have to create the Voice VLAN on both switches and then run the command "IP Helper Address" to specify a DHCP server? From what i've been reading it's required, when using Inter-VLAN routing, to configure the VLAN interface with an IP address. But it's going to give problems when both switches are connected to eachother and both have the same VLAN configured including the same IP address assigned to their VLAN interface?
Normal data should pass the ASA firewall, VOIP traffic should go through the Vigor modem to a hosted VOIP provider. The best way, i assume, is to configure 2 separate scopes on the DHCP server?
Still confused on how to set it up, hope that someone can point me in the right direction

If you're sending voice to only the Vigor modem then there is no need for a trunk between the SF-300 and the Vigor modem. You can just set that to an untag packet for the VLAN 2 between that switch and the Vigor modem.
On the 'edge' SF300 where the IP phone/PC is it is obviously going to interoute there and of course the phone port is tagged and PC port is untagged.
For the IP helper, it uses UDP-RELAY and it should be enabled on the port itself and enabled on the global configuration. You may also need option 82. Also keep in mind, depending how your DHCP server works, it may need option 82 configured as well or at least a route to understand the subnets in the layer 3 environment to get traffic across the VLANS.

but system could not modify $voice_vlan value.
how to fix it ?

Hi Skywings,
So I am guessing the above output is after the change, right? If this is true it looks like something went wrong during the configuration process. Auto Voice VLAN process has two main phases where the first one is related to communication between switches and other Cisco infrastructure devices and synchronizing the Voice VLAN ID. The second phase is related to identifying the end device as phone. What I can see in your case that the first phase is failing somehow since the voice VLAN ID is different than locally configured. Can you share with me your running and also startup config plus CDP neighbours? You may use private message.
Regards,
Aleksandra

Phone not picking up Voice VLAN

Hi All,
Strange issue that's just started happening with a few 6921 phones.
On our cisco switch when port is configured with data and voice vlan, the phone picks up an IP address from the data vlan and in turn doesn't register. It's as if it doesn't see the voice vlan. As soon I remove the data vlan and have voice vlan only on the port, phone picks up IP from the voice network and registers against the CME. This all worked before on the same ports, nothing changed. It just suddenly stopped working.
Anyone seen this before?
Thanks

Hi,
Ok first output is when the phone doesn't work. VLAN 7 is the data vlan and 81 is Voice on this LAN.
