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
