CAM optimization

When this command is enabled, if a Policy Map containing classification rules (ACL and/or dscp/

ip-precedence rules) is applied to more than one physical interface on the same port-pipe, only a single

copy of the policy is written (only 1 FP entry will be used). When the command is disabled, the system

behaves as described in this chapter.

test cam-usage

This command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS

optimization for IPv6 ACLs.

Use this command to determine whether sufficient ACL CAM space is available to enable a service-policy .

Create a Class Map with all required ACL rules, then execute the

mode to verify the actual CAM space required. The example below gives a sample of the output shown

when executing the command. The status column indicates whether or not the policy can be enabled.
