Configuring a Port to Connect to a Cisco 7690 IP Phone
Because a Cisco 7960 IP phone also supports connection to a PC or another device, an interface
connecting a Catalyst 4500 series switch to a Cisco 7960 IP phone can carry a mix of voice and data
traffic.
There are three configurations for a port connected to a Cisco 7960 IP phone:
•
•
•
To configure a port to instruct the phone to give voice traffic a higher priority and to forward all traffic
through the 802.1Q native VLAN, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface {fastethernet |
gigabitethernet} slot/port
Step 3
Switch(config-if)# switchport voice vlan dot1p
Step 4
Switch(config-if)# end
Step 5
Switch# show interface {fastethernet |
gigabitethernet} slot/port switchport

Configuring Voice Ports for Voice and Data Traffic

Because voice and data traffic can travel through the same voice port, you should specify a different
VLAN for each type of traffic. You can configure a switch port to forward voice and data traffic on
different VLANs.

All traffic is transmitted according to the default CoS priority of the port. This is the default.
Voice traffic is given a higher priority by the phone (CoS priority is always 5), and all traffic is in
the same VLAN.
Voice and data traffic are carried on separate VLANs.
See the "Using 802.1X with Voice VLAN Ports" section on page 31-10
