Have a set of non-cisco ip phones (dont do CDP). However they do VLAN and CoS. I have set VLAN on the phone to 100 and CoS 5.
I have a series of Cisco 2950 and Catalyst 500. I have configured in both of them Voice VLAN to 100. Configured the ports on the switches as trunk. In the 2950 series, there is the option to trust the CoS of IP phone but not in catalyst 500.
What I would like to know since both VLAN IDs coincide (although the phone doesnt do CDP), will the Cisco switch:
1)understand that the VLAN coming in from the IP phone is actually a Voice VLAN and treat it as such
2) secondly will it trust the Cos from the phone?
