Chapter 24 Configuring QoS
Beginning in privileged EXEC mode, follow these steps to modify the DSCP-to-CoS map:
Command
Step 1
configure terminal
Step 2
mls qos map dscp-cos dscp-list to cos
Step 3
end
Step 4 show mls qos maps dscp-to-cos
Step 5
copy running-config startup-config
To return to the default map, use the no mls qos map dscp-cos global configuration command.
This example shows how the DSCP values 26 and 48 are mapped to CoS value 7. For the remaining
DSCP values, the DSCP-to-CoS mapping is the default.
Switch(config)#mls qos map dscp-cos 26 48 to 7
Switch(config)#exit
Switch#show mls qos maps dscp-cos
