Step 6
end
Return to privileged EXEC mode.
Step 7
copy running-config startup-config
Save the settings in the configuration file.
Note:
In Trust 802.1p mode, the untagged packets will be added an 802.1p priority based on the port to
802.1p mapping and will be forwarded according to the 802.1p to queue mapping.
The following example shows how to configure the trust mode of port 1/0/1 as dot1p, map
802.1p priority 3 to TC4, and configure to map the original 802.1p 1 to 802.1p priority 3:
Switch#configure
Switch(config)#interface gigabitEthernet
1/0/1
Switch(config-if)#qos trust mode
dot1p
Switch(config-if)#exit
Switch(config)#qos cos-map

Switch(config)#qos dot1p-remap
1 3
Switch(config)#show qos trust interface gigabitEthernet
