i am trying to find the best practice for setting up Avaya IP phones on a cisco network. In my experience in the Cisco VOIP world we would use the switchport voice vlan # due to the fact that cisco understands CDP. However, Avaya would use LLDP therefore two things would need to be considered:
1. does the switch support CDP?
2. would Switchport voice vlan # propagate to the phone once connected?
any insights would be appreciated it.
