Service Manual
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 linecards or 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.
