QoS Optimization for IPv6 ACLs does not impact the CAM usage for applying a policy on a single (or
the first of several) interfaces. It is most useful when a policy is applied across multiple interfaces; it
can reduce the impact to CAM usage across subsequent interfaces.
Example
The following examples show some sample output when using the test cam-usage command.

Term Explanation
Linecard
Lists the line card or linecards that are checked. Entering
all shows
the status for linecards in the chassis
Portpipe Lists the portpipe (port-set) or port pipes (port-sets) that are checked.
Entering all shows the status for linecards and port-pipes in the
chassis.
CAM Partition Shows the CAM profile of the CAM
Available CAM Identifies the amount of CAM space remaining for that profile
Estimated CAM per Port Estimates the amount of CAM space the listed policy will require.
Status Indicates whether or not the policy will be allowed in the CAM
