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.

The following describes output from the text cam-usage service-policy input

policy-map stack-unit command shown in the Example below.

Field Description

Stack-Unit Indicates the stack-unit 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 stack-unit/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.

NOTE: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed; therefore, the output

contains only L2ACL CAM partition entries.

Example

FTOS# test cam-usage service-policy input pmap_l2 stack-unit

For a L2 Input Policy Map pmap_l2, the output must be as

follows,
