• 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 parenthesis.

• 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.

Figure 39-13. test cam-usage Command Example

Note: The command show cam-usage provides much of the same information as test cam-usage, but

whether or not 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 command

test cam-usage is useful

because it provides this measurement.
