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
Dell#test cam-usage service-policy input test-cam-usage stack-unit 2 po 0
