Test CAM Usage

To determine whether sufficient CAM space is available to enable a service-policy, use the test-cam-usage
command. To verify the actual CAM space required, create a Class Map with all required ACL rules, then
execute the test cam-usage command in Privilege mode. The Status column in the command output
indicates whether or not you can enable the policy.
Example of the test cam-usage Command
