Configuring QoS Class of Service Configuration
Step 4 For Certain Devices:
show qos dscp-map interface [fastEthernet
port
| gigabitEthernet
port
| ten-
gigabitEthernet
port
| port-channel
port-channel-id
]
Verify the DSCP to queue mappings of ports.
For Certain Devices:
show qos dscp-map
Verify the DSCP to queue mappings globally.
Step 5 For Certain Devices:
show qos dscp-remap interface [fastEthernet
port
| gigabitEthernet
port
| ten-
gigabitEthernet
port
| port-channel
port-channel-id
]
Verify the DSCP to DSCP mappings of the ports.
For Certain Devices:
show qos dscp-remap
Verify the DSCP to DSCP mappings globally.
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 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
