Test CAM Usage
The test cam-usage command applies to both IPv4 and IPv6 CAM proles, but is best used when verifying QoS optimization for IPv6
ACLs.
Use this command to determine whether sucient ACL CAM space is available to enable a service-policy. Create a Class Map with all
required ACL rules, then execute the
test cam-usage command in Privilege mode to verify the actual CAM space required. The Status
column in the command output indicates whether or not the policy can be enabled.
Example of the test cam-usage Command
Dell# test cam-usage service-policy input pcam linecard all
