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.

Usage
The following describes the test cam-usage command shown in the Example
Information
below.
Term
Stack-Unit
442
Explanation
Lists the stack unit or units that are checked. Entering all
shows the status for all stacks.
Lists the portpipe (port-set) or port pipes (port-sets) that are
checked. Entering all shows the status for linecards and
port-pipes in the chassis.
Shows the CAM profile of the CAM.
Identifies the amount of CAM space remaining for that
profile.
Estimates the amount of CAM space the listed policy will
require.
Indicates whether or not the policy will be allowed in the
CAM.
Explanation
Lists the stack unit or units that are checked. Entering all
shows the status for all stacks.
