Usage

Information

This features allows you to determine if the CAM has enough space available before applying the

configuration on an interface.

An input policy map with both Trust and Class-map configuration, the Class-map rules are ignored and

only the Trust rule is programmed in the CAM. In such an instance, the Estimated CAM output column

will contain the size of the CAM space required for the Trust rule and not the Class-map rule.

Note: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed and hence the output contains only

L2ACL CAM partition entries.

Field Description

Linecard Indicates the line card slot number.

Portpipe Indicates the portpipe number.

CAM Partition The CAM space where the rules are added.

Available CAM Indicates the free CAM space, in the partition, for the classification rules.

Note: The CAM entries reserved for the default rules are not included in the

Available CAM column; free entries, from the default rules space, can not be used

as a policy map for the classification rules.

Estimated CAM per Port Indicates the number of free CAM entries required (for the classification rules) to

apply the input policy map on a single interface.

Note: The CAM entries for the default rule are not included in this column; a

CAM entry for the default rule is always dedicated to a port and is always

available for that interface.

Status (Allowed ports) Indicates if the input policy map configuration on an interface belonging to a

linecard/port-pipe is successful—Allowed (n)—or not successful—Exception.

The allowed number (n) indicates the number of ports in that port-pipe on which

the Policy Map can be applied successfully.
