Test CAM Usage
The test cam-usage command applies to both IPv4 and IPv6 CAM profiles, but is best used when
verifying QoS optimization for IPv6 ACLs.
Use this command to determine whether sufficient 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
linecard | Portpipe | CAM Partition | Available CAM | Estimated CAM per Port
