Chapter 2 Cisco ME 2400 Ethernet Access Switch Cisco IOS Commands

policer cpu uni

Use the policer cpu uni global configuration command to configure the CPU policing threshold for all

user network interfaces (UNIs) and enhanced network interfaces (ENIs) on the switch. Use the no form

of this command to return to the default.

policer cpu uni rate-bps

no policer cpu uni

Syntax Description

Defaults The default policing threshold is 160000 bps.

Command Modes Global configuration

Command History

Usage Guidelines To protect against accidental or intentional CPU overload, the Cisco ME switch automatically provides

control-plane security by dropping or rate-limiting a predefined set of Layer 2 control packets and some

Layer 3 control packets for UNIs and ENIs. The switch pre-allocates 27 control-plane security policers

for CPU protection, numbered 0 to 26. A policer of 26 means a drop policer. A policer of a value of 0 to

25 means that a rate-limiting policer is assigned to the port for the control protocol.

CPU policers are pre-allocated. You can configure only the rate-limiting threshold by using the policer

cpu uni rate-bps command. The configured threshold applies to all control protocols and all UNIs and

ENIs.

For more information about control-plane security, see the software configuration guide for this release.

Examples This example shows how to set CPU protection threshold to 10000 bps and to verify the configuration.

Switch# config t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# policer cpu uni 10000

Switch(config)# end

You can verify your settings by entering the show policer cpu uni-eni rate privileged EXEC command.
