NOTE
To configure a class map in the policy-map you must create the class map first using the class-
map command while in global configuration mode. Refer to
Configuring a policer class map on
page 505.
4. Provide a policing parameter for the class map. This enables policy-class-map policer configuration
mode.
switch(config-policymap-class)# police cir 4000000
5. Enter another parameter as applicable.
(config-policymap-class-police)# cbs 50000
6. Enter additional parameters as applicable.
switch(config-policymap-class-police)# eir 800000 ebs 400000 conform-set-tc 3
exceed-set-prec 4
7. Exit the policy-class-map Policer configuration mode.
switch(config-policymap-class-police)# exit
8. Exit the policy-class-map configuration mode.
switch (config-policymap-class)# exit
9. Exit the policy-map configuration mode.
switch(config-policymap)# exit
10.Return to privileged EXEC mode.
switch(config)# end
11.Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Attaching the mutation to the class
You can specify the mutation-map to be used on a port. This can lead to possible contradictions if
there are other user-defined classes used in the same policy-map that have a set cos action
configured. In this case-defined cos takes priority over the mutation map.
Perform the following task in global configuration mode.
1. Select the policy map.
switch(config)# policy-map p1
2. Select the class.
switch(config-policymap)# class class-default
3. Specify the mutation map to be used on the port. Different kinds of mutations can be used
depending on the command. For complete information, refer to Network OS Command Reference.
The available commands are:
• cos-mutation
• cos-traffic-class
• dscp-mutation
• dscp-cos
• dscp-traffic-class
switch(config-policyclass)# cos-mutation plsmap
Attaching the port-shaper to the class
You can specify the shaping rate per port attached to the policy map. You can use this command to
smooth out the traffic egressing an interface. This command is allowed only for the egress direction.
This command is mutually exclusive of the scheduler and police commands.
Perform the following task in global configuration mode.
