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. .
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.
