Override the default mapping by creating a user-dened DSCP trust map. All the unspecied DSCP entries mapp to the default trac class
ID 0.
Congure user–dened DSCP trust map
1 Create a DSCP trust map.
OS10(config)# trust dscp-map dscp-trust-map
OS10(config-tmap-dscp-map)#
2 Dene the set of dscp values mapped to trac-class, the qos-group ID.
OS10(config-tmap-dscp-map)# qos-group 3 dscp 0-15
OS10(config-tmap-dscp-map)# qos-group 5 dscp 16-30
3 Verify the map entries.
OS10# show qos maps type trust-map-dscp dscp-trust-map
