Hi
could any one advice me about "switchport voice vlan"?
I have a configuration like:
interface GigabitEthernet 1/-/1
description test phone
switch port access vlan 100
switchport mode access
switchport voice vlan 200
when I plug a no-cisco phone into this port, the phone try to get dhcp from vlan100, not vlan 200.
do I have any chance to force it go to vlan 200? o
Any comments will be appreciate
Thanks in advance

Hi
Most IP phones have some mechanism for setting the VLAN - Cisco phones use CDP, but other phones do not. Check with the manufacturer, or post up the type of phone you have.
For example, some phones require you to set custom DHCP options to set the VLAN.

Some non-Cisco phones understand LLDP. LLDP also allows you to give voice- information to the phone. See if your phones and switches support LLDP!
