Chapter 1 Configuring Voice VLAN
Displaying Voice VLAN
Beginning in privileged EXEC mode, follow these steps to set the priority of data traffic received from
the nonvoice port on the Cisco IP Phone:
This example shows how to configure a port connected to a Cisco IP Phone to not change the priority of
frames received from the PC or the attached device:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# switchport priority extend trust
Switch(config-if)# end
To return the port to its default setting, use the no switchport priority extend interface configuration
command.
Displaying Voice VLAN
To display voice VLAN configuration for an interface, use the show interfaces interface-id switchport
privileged EXEC command.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the interface connected to the Cisco IP Phone, and enter interface
configuration mode.
Step 3
switchport priority extend
{cos value | trust}
Set the priority of data traffic received from the Cisco IP Phone access port:
• cos value—Configure the phone to override the priority received from the
PC or the attached device with the specified CoS value. The value is a
number from 0 to 7, with 7 as the highest priority. The default priority is
cos 0.
• trust—Configure the phone access port to trust the priority received from
the PC or the attached device.
Step 4
end Return to privileged EXEC mode.
Step 5
show interfaces interface-id
switchport
Verify your entries.
Step 6
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
