Test CAM Usage
To determine whether suîš„cient 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
DellEMC#test cam-usage service-policy input test-cam-usage stack-unit 1 po 0
