Issue with voice vlan on 3560G-48PS code 12.2(35)SE5
I have an issue where I will add switchport voice vlan x on to the switchport, the ip phone (polycom talking cdp) will work fine on some occasions but not others. If I reboot switch the vlans will not come up automatically on the voice vlan, however if I add the voice vlan one interface at a time they will work but only after the reboot. If a phone gets disconnected for any reason, it will only pick up the data vlan! Also, it wont seem to work if I use the range command, I have to do it one at a time. As you can see results are not consistent. A sho arp on the mac will tell you it has mapped the mac with the new address on the voice vlan but I wont be able to ping it and it is down.
The config is :-
switchport access vlan 2
switchport mode access
switchport voice vlan 4
mls qos vlan-based
I also have tried clear the arp cache doesnt make any difference.
