Chapter 2 Catalyst 3560 Switch Cisco IOS Commands trust If you specify trust ip-precedence, QoS uses the IP precedence value from the ingress packet and the IP-precedence-to-DSCP map. For non-IP packets that are tagged, QoS uses the received CoS value; for non-IP packets that are untagged, QoS uses the default port CoS value. In either case, the DSCP for the packet is derived from the CoS-to-DSCP map. To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command. Examples This example shows how to define a port trust state to trust incoming DSCP values for traffic classified with class1: Switch(config)# policy-map policy1 Switch(config-pmap)# class class1 Switch(config-pmap-c)# trust dscp Switch(config-pmap-c)# police 1000000 20000 exceed-action policed-dscp-transmit Switch(config-pmap-c)# exit You can verify your settings by entering the show policy-map privileged EXEC command. Related Commands Command class police policy-map set show policy-map Description Defines a traffic classification match criteria (through the police, set, and trust policy-map class configuration commands) for the specified class-map name.
