•
test cam-usage service-policy input policy-map linecard {0–2} all
The output of this command, shown in the following example, displays:
• The estimated number of CAM entries the policy-map will consume.
• Whether or not the policy-map can be applied.
• The number of interfaces in a port-pipe to which the policy-map can be applied.
Specifically:
• Available CAM — the available number of CAM entries in the specified CAM partition for the specified
line-card port pipe.
• Estimated CAM — the estimated number of CAM entries that the policy will consume when it is applied
to an interface.
• Status — indicates whether the specified policy-map can be completely applied to an interface in the
port-pipe.
• Allowed — indicates that the policy-map can be applied because the estimated number of CAM
entries is less or equal to the available number of CAM entries. The number of interfaces in the
port-pipe to which the policy-map can be applied is given in parentheses.
• Exception — indicates that the number of CAM entries required to write the policy-map to the
CAM is greater than the number of available CAM entries, and therefore the policy-map cannot be
applied to an interface in the specified port-pipe.
NOTE: The show cam-usage command provides much of the same information as the test cam-
usage command, but whether a policy-map can be successfully applied to an interface cannot be
determined without first measuring how many CAM entries the policy-map would consume; the test
cam-usage command is useful because it provides this measurement.
• Verify that there are enough available CAM entries.

SNMP Support for Buffer Statistics
Tracking
SNMP support for buffer statistics tracking (BST) counters is implemented in the F10-FPSTATS MIB. BST
counters allow you to better monitor system resources and allocate buffer memory.
BST counters include the Max Use Count statistic, which provides the maximum counter value over a period
of time.
In the F10-FPSTATS MIB, the following tables display BST counters:
