control-plane command.
control-plane

Command Modes Global configuration mode
Command History
Usage Guidelines After you enter the control-plane command, you can define control plane services for your route
processor. For example, you can associate a service policy with the control plane to police all traffic that
is destined to the control plane.
Examples These examples show 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
Switch(config-pmap)# class telnet-class
Switch(config-pmap-c)# police 32000 1000 conform transmit exceed drop
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
