I am setting up the above for Avaya phones. The sites with separate router/switch combos work fine.
The FA port settings are as follows:
description * Data/Voice Vlan's *
switchport access vlan 20
switchport voice vlan 852
mls qos trust dscp
We have 2 Vlan interfaces set up - 1 for voice and one for data. (20 is data and 852 is voice.
If I plug a laptop in, I get an IP address from the off-site DHCP server.
If I plug the phone in, it get the Vlan number (852) from the scope option properly.
If I change the port to
switchmode access vlan 852
and plug the laptop in, I get a voice IP address.
If I plug the phone in, it gets it's voive IP address and loads it's config. But I can't get a data IP for the PC.
I do a show vlan-sw and see that all of the ports are assigned to Vlan 20 but none are co-assigned to Vlan 852.
The 3550's, 3750's, etc. at other sites have both Vlan's assigned to each port.
What am I missing?
