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. C9000 Series Syntax Parameters test cam-usage service-policy input policy-map-name linecard {number portset {port-pipe-number} | all} input policy-map- Enter the name of the policy map to verify. Maximum is 32 characters. name linecard number portset port-pipenumber Enter a line card and port-pipe number to check CAM usage on specified ports. The range of valid port-pipe numbers is 0 to 3. Enter linecard all to verify the CAM space available for all ports on the switch. Defaults None Command Modes EXEC Privilege Command History This guide is platform-specific.

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. Content Addressable Memory (CAM) 657
