4. Apply the map on a specific interface or on system-qos, global level.
● Interface level
OS10(conf-if-eth1/1/1)# trust-map dot1p example-dot1p-trustmap-name
NOTE: In the interface level, the no version of the command returns the configuration to the system-qos level. If
there is no configuration available at the system-qos level, the configuration returns to default mapping.
● System-qos level
OS10(config-sys-qos)# trust-map dot1p example-dot1p-trustmap-name
Apply CoS trust map
After you create a trust map, you must apply the trust map at the interface or system-qos level. To apply the trust map on a
specific interface or on system-qos (global) level:
● Interface level
OS10(conf-if-eth1/1/1)# trust-map dot1p example-dot1p-trustmap-name
NOTE: In the interface level, the no version of the command returns the configuration to system-qos level. If there is
no configuration available at the system-qos level, then the configuration returns to default mapping.
● System-qos level
OS10(config-sys-qos)# trust-map dot1p example-dot1p-trustmap-name

Assign a predefined and reserved trust classification in the policy map for the DSCP flow. Weighted random early detection
(WRED) uses the color assigned to a particular traffic to determine the drop-probability and threshold.
