test cam-usage
Verify that enough ACL CAM space is available for the IPv6 ACLs you have created.
Syntax
test cam-usage service-policy input input policy name linecard {number |
all}
Parameters
policy-map name Enter the name of the policy-map to verify.
number Enter all to get information for all the linecards, or enter the linecard number
to get information for a specific card. The range is 0-6 for E-Series and 0-7 for
C-Series.
Defaults none

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 Example below.
Term Explanation
Linecard Lists the line card or linecards that are checked. Entering all shows the status for
linecards in the chassis.
Portpipe 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.
CAM Partition Shows the CAM profile of the CAM.
Available CAM Identifies the amount of CAM space remaining for that profile.
Estimated CAM
per Port
Estimates the amount of CAM space the listed policy requires.
Status Indicates whether or not the policy is allowed in the CAM
