Test CAM Usage
The test cam-usage command is supported on the S5000 platforms.
This command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS optimization for IPv6 ACLs.
To determine whether sufficient ACL CAM space is available to enable a service-policy, use this command. To verify the actual
CAM space required, create a class map with all the required ACL rules, then execute the test cam-usage command in
Privilege mode. The following example shows the output when executing this command. 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
