Command Line Reference Guide

Version Description
7.8.1.0 Introduced on the C-Series and E-Series TeraScale.
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
