To configure the way in which the Cisco IP phone transmits data traffic, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# mls qos trust extend
[cos cos_value]
Router(config-if)# no mls qos trust extend
Step 3
Router(config)# end
Step 4
Router# show interface type slot/port switchport
Router# show running-config interface type
slot/port

This example shows how to configure Fast Ethernet port 5/1 to send CDP packets that tell the
Cisco IP phone to configure its access port as untrusted and to mark all tagged traffic received from a
device connected to the access port on the Cisco IP phone with CoS 3:
Router# configure terminal
Router(config)# interface fastethernet 5/1
Router(config-if)# mls qos trust extend cos 3
This example shows how to configure Fast Ethernet port 5/1 to send CDP packets that tell the
Cisco IP phone to configure its access port as trusted:
Router# configure terminal
Router(config)# interface fastethernet 5/1

connected to the access port on the Cisco IP phone, do not enter the cos keyword and CoS value.
To send CDP packets that configure the Cisco IP phone to mark tagged ingress traffic received from
a device connected to the access port on the Cisco IP phone, enter the cos keyword and CoS value
(valid values are 0 through 7).
You cannot use Cisco IOS software commands to configure whether or not traffic sent from a device
