Command
FTOS# test cam-usage service-policy input pmap_l2 linecard all
For a L2 Input Policy Map pmap_l2, the output must be as follows,

Note:
In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed and hence the output
contains only L2ACL CAM partition entries.

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.

Description
Indicates the line card slot number.
Indicates the portpipe number.
The CAM space where the rules are added.
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.
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.
Indicates if the input policy map configuration on an interface belonging
to a line card/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.
