Testing CAM Usage for QoS Policies

The test cam-usage command applies to the IPv4 ingress CAM partition.

To determine whether there is sucient space in this CAM region for the ACLs created in QoS service-policies, use this command.

You can create a class map with all required ACL rules and then enter the test cam-usage command in Privilege mode to verify the

actual CAM space required. The following example shows the command output. The status column indicates whether you can enable the

policy.

Example of the test cam-usage Command

Dell# test cam-usage service-policy input TestPolicy stack-unit all
