service-policy input (control-plane)
service-policy input (control-plane)
To attach a policy map to a control plane for aggregate control plane services, use the service-policy
input command. Use the no form of this command to remove a service policy from a control plane.
service-policy input policy-map-name
Syntax Description
Defaults No service policy is specified.
Command Modes Control-plane configuration mode
Command History
Usage Guidelines In this release, the only policy-map accepted on the control-plane is system-cpp-policy. It is already
attached to the control-plane at start up. If not (due to some error conditions), it is recommended to use
the global macro system-cpp command to attach it to the control-plane. The system-cpp-policy created
by the system contains system predefined classes. For these predefined classes, you can change the
policing parameters but you should not make any other change to the classes.
You can define your own class-maps and append them to the end of the system-cpp-policy policy-map.
Examples This example shows how to configure trusted hosts with source addresses 10.1.1.1 and 10.1.1.2 to
forward Telnet packets to the control plane without constraint, while allowing all remaining Telnet
packets to be policed at the specified rate:
Switch(config)# access-list 140 deny tcp host 10.1.1.1 any eq telnet
! Allow 10.1.1.2 trusted host traffic.
Switch(config)# access-list 140 deny tcp host 10.1.1.2 any eq telnet
! Rate limit all other Telnet traffic.
Switch(config)# access-list 140 permit tcp any any eq telnet
! Define class-map “telnet-class.”
Switch(config)# class-map telnet-class
Switch(config-cmap)# match access-group 140
Switch(config-cmap)# exit
Switch(config)# policy-map control-plane-policy
Switch(config-pmap)# class telnet-class
Switch(config-pmap-c)# police 80000 conform transmit exceed drop
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
! Define aggregate control plane service for the active Route Processor.
input Applies the specified service policy to the packets that are entering the
control plane.
policy-map-name Name of a service policy map (created using the policy-map command) to
be attached.
Release Modification
12.2(31)SG Support for this command was introduced on the Catalyst 4500 series switch.
