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
Linecard Lists the line cards that are checked. Entering all displays the status for line
cards in the chassis.
Portpipe Lists the port pipes (port sets) that are checked. Entering all displays the
status for all line cards 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.
