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.
