QoS Optimization for IPv6 ACLs does not impact the CAM usage for applying a policy on a single (or the rst 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.
The following describes the test cam-usage command shown in the following example.
Term Explanation
Stack-Unit
Lists the stack unit or units that are checked. Entering all shows the status for all stacks.
Portpipe Lists the portpipe (port-set) or port pipes (port-sets) that are checked. Entering all
shows the status for stack-units and port-pipes in the chassis. The port set value is from
0 to 0.
CAM Partition Shows the CAM prole of the CAM.
Available CAM Identies the amount of CAM space remaining for that prole.
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.
