Configuring Voice VLANs

Example: Configuring a Port Connected to an IP Phone Not to Change Frame Priority

This example shows how to enable switch port voice detect on a Cisco IP Phone:

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# interface gigabitethernet 1/0/1 Switch(config-if)# switchport voice?

detect detection enhancement keyword vlan VLAN for voice traffic

Switch(config-if)# switchport voice detect? cisco-phone Cisco IP Phone

Switch(config-if)#switchport voice detect cisco-phone? full-duplex Cisco IP Phone

Switch(config-if)#switchport voice detect cisco-phone full-duplex full-duplex full duplex keyword

Switch(config-if)# end

This example shows how to disable switchport voice detect on a Cisco IP Phone:

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface gigabitethernet 1/0/1

Switch(config-if)#no switchport voice detect cisco-phone

Switch(config-if)#no switchport voice detect cisco-phone full-duplex
