Usage
This features allows you to determine if the CAM has enough space available before applying
Information
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.
The following describes the text cam-usage service-policy input policy-
map linecard command shown in the Example below.

Introduced on the C-Series and S-Series.
Introduced on the E-Series.
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 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.
NOTE: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed; therefore, the output
contains only L2ACL CAM partition entries.
