Usage Information

This command applies to both IPv4 and IPv6 CAM Profiles, but is best used when verifying QoS optimization for IPv6 ACLs.

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.

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 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.
