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 examples show some
sample output when using the test cam-usage command.
