test cam-usage
Verify the CAM space that is available for IPv4 and IPv6 CAM profiles, and particularly to verify if enough CAM
space is available for the IPv6 ACLs you use in a policy map.

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.
