Usage
This feature allows you to determine if the CAM has enough space available before
Information
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 contains 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 following example.

Description
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, cannot 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.
