Userdefined DCSP trust map
You can override the default mapping by creating a user defined DSCP trust map. All the unspecified DSCP entries are mapped
to the default traffic class ID 0.
Configure userdefined DSCP trust map
1. Create a DSCP trust map.
OS10(config)# trust dscp-map dscp-trust-map
OS10(config-tmap-dscp-map)#
2. Define the set of dscp values mapped to traffic-class(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
DSCP Priority to Traffic-Class Map : dscp-trust-map
Traffic-Class DSCP Priority
-------------------------------
3 0-15
5 16-30
4. Apply the map on a specific interface or on system-qos (global) level.
Interface level
OS10(conf-if-eth1/1/1)# trust-map dscp dscp-trust-map
System-qos level
OS10(config-sys-qos)# trust-map dscp dscp-trust-map
Configure default DSCP trust map
1. Create a default DSCP trust map.
OS10(config)# trust dscp-map default
OS10(config-tmap-dscp-map)#
2. Apply the map on a specific interface or on system-qos (global) level.
Interface level
OS10(conf-if-eth1/1/1)# trust-map dscp default
