All other profile allocations can use either even or odd numbered ranges. You must save the new CAM settings to the startup-config (write-mem or copy run start) then reload the system for the new settings to take effect. CAM optimization c s CAM optimization is supported on platforms 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 c e s The test cam-usage command is supported on platforms 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 test cam-usage command in Privilege 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.
