2. Define the set of dot1p values mapped to traffic-class, the qos-group ID. OS10(config-tmap-dot1p-map)# qos-group 3 dot1p 0-4 OS10(config-tmap-dot1p-map)# qos-group 5 dot1p 5-7 3. Verify the map entries. OS10# show qos maps type trust-map-dot1p example-dot1p-trustmap-name DOT1P Priority to Traffic-Class Map : example-dot1p-trustmap-name Traffic-Class DOT1P Priority 3 0-4 5 5-7 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 DSCP trust map: 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. Table 82. Default DSCP trust map DSCP values Traffic class ID Color 0-3 0 G 4-7 0 Y 8-11 1 G 12-15 1 Y 16-19 2 G 20-23 2 Y 24-27 3 G 28-31 3 Y Quality of service 1317
