Command Usage
The set ip dscp command is used to set the priority values in the packet’s ToS field
for matching packets.
Example
This example creates a policy called “rd-policy,” uses the class command to specify
the previously defined “rd-class,” uses the set ip dscp command to classify the
service that incoming packets will receive, and then uses the police flow command
to limit the average bandwidth to 100,000 Kbps, the burst rate to 4000 bytes, and
configure the response to drop any violating packets.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set ip dscp 3
Console(config-pmap-c)#police flow 10000 4000 conform-action transmit
violate-action drop
Console(config-pmap-c)#
