Hello all,
I recently took over a cisco network that is using an old NBX v3000 phone system with 3 com voip phones. They just purchased another NBX for our other site (we have a direct connection between the sites). The last network admin was able to get the first NBX phone system set working using the voice vlan connection.
The current system uses vlan 15 for voice and a port set up like this works fine:
switchport access vlan 13
switchport mode access
switchport nonegotiate
switchport voice vlan 15
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust cos
auto qos trust
spanning-tree portfast
I have a phone hooked to the port, it boots, hits the nbx on vlan 15 and downloards an image and gets an extension.
For the new system I set up Vlan 116 to be its voice vlan.
If I change the config:
switchport access vlan 13
switchport mode access
switchport nonegotiate
switchport voice vlan 116
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust cos
auto qos trust
spanning-tree portfast
The phone boots but just sets there waiting "waiting for NCP"
Anywhere on either site, if I use voice vlan 15 the phone will connect, but if I use 116 it will not.
Both vlans 15, and 116 are set up the same way one the same switch. they both have an ip address, 10.15.1.1 255.255.0.0 and 10.116.1.1 255.255.0.0. Both vlans are trunked, and I can ping their address from other switches across both sites. Neither vlan has an access list applied to it.
Both NBX's are configured with IPs (10.15.1.190 and 10.116.1.190), and vlan tagging.
One thing I have noticed, if I issue the "show mac address-table interface" command to a port using the voice vlan 15 the phones mac is on vlan 15. If I issue the same command with the voice vlan set to 116 the phones mac will be on the access vlan. If I remove the access vlan and only include the voice vlan 116 the mac will show up on Vlan 1...
I feel like the issue is with my vlan 116, though after looking through config after config I cant see a difference between my set up and the last network admin's set up.
Does anyone have any ideas of any other config options that I may need to get this working?
Thanks at ton!

What about you dhcp pool? Can you post the full switch and router config?

There are the show commands, as I said, if I change the 116 to 15 the phone connects to the vlan 15 nbx right away.
we are not using DHCP for the phones, they connect back to the NBX with their mac address.

This is the current config using the commands you suggested. Still no connection. There has to be something with Vlan 116 that is keeping the tagged vlan data from making it to the nbx.
I can ping from the swith to the NBX
Dcore#ping 10.116.1.190
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.116.1.190, timeout is 2 seconds:

can you post full topology snapshot along with full config of devices?
04-05-2013 11:47 AM
Hi Donald.
On the interface G1/0/22
put this command
switchport mode trunk
switchport trunk allowed vlan 116
Hope this helps
Regards
Carlo
