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.
