class
Examples This example shows how to create a policy map called policy1. When attached to the ingress direction,
it matches all the incoming traffic defined in class1, sets the IP Differentiated Services Code Point
(DSCP) to 10, and polices the traffic at an average rate of 1 Mb/s and bursts at 20 KB. Traffic exceeding
the profile is marked down to a DSCP value gotten from the policed-DSCP map and then sent.
Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap-c)# police 1000000 20000 exceed-action policed-dscp-transmit
