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

FTOS#
Usage
Information
This features allows you to determine if the CAM has enough space available before applying the
configuration on an interface.
Version 9.0.2.0 Introduced on the S6000.
Version 8.3.11.1 Introduced on Z9000
Note: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed and hence the output
contains only L2ACL CAM partition entries.
Table 35-2. test cam-usage Command Example Fields
Field Description
Stack-unit Indicates the stack-unit 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.
