Version 9.9(0.0) 9.2(1.0) 8.3.19.0 8.3.11.1 8.3.7.0 7.8.1.0 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Introduced. 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 Linecard Portpipe CAM Partition Available CAM Estimated CAM per Port Status Explanation Lists the line cards that are checked. Entering all displays the status for line cards in the chassis. Lists the port pipes (port sets) that are checked. Entering all displays the status for all line cards 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.
