Test CAM Usage
The test cam-usage command is supported on the S4820T platform.
This 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
FTOS#test cam-usage service-policy input TestPolicy linecard all

View CAM Profiles
To view the current CAM profile for the chassis and each component, use the show cam-profile command.
This command also shows the profile that is loaded after the next chassis or component reload.
Example of the show cam-profile Command
FTOS#show cam-profile
