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
test cam-usage service-policy input policy-map-name linecard {number portset
{port-pipe-number} | all}
Parameters
input policy-map-
name
Enter the name of the policy map to verify. Maximum is 32 characters.
linecard number
portset port-pipe-
number
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. For command information about other platforms, see the relevant Dell Networking
OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.9(0.0) Introduced on the C9010.
9.2(1.0) Introduced on the Z9500.
8.3.19.0 Introduced on the S4820T.
8.3.11.1 Introduced on the Z9000.

7.8.1.0 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 Explanation
Linecard Lists the line cards that are checked. Entering all displays the status for line cards in the
chassis.
Portpipe Lists the port pipes (port sets) that are checked. Entering all displays the status for all
line cards 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 will require.
Status Indicates whether or not the policy will be allowed in the CAM.
