Note:
In Trust DSCP mode, non-IP 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 dscp, map
802.1p priority 3 to TC4, map DSCP priority 1-3,5,7 to 802.1p priority 3, and configure to
map the original DSCP priority 9 to DSCP priority 5:
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#qos trust mode dscp
Switch(config-if)#exit
Switch(config)#qos cos-map 3 4
Switch(config)#qos dscp-map 1-3,5,7 3
Switch(config)#qos dscp-remap 9 5
Switch(config)#show qos trust interface gigabitEthernet 1/0/1
