• Status indicates whether or not 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 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.

Viewing QoS CAM Entries
Viewing QoS CAM Entries is supported only on platform
e
• View Layer 2 QoS CAM entries using the command
show cam layer3-qos
from EXEC Privilege mode.
• View Layer 3 QoS CAM entries using the command
show cam layer2-qos
from EXEC Privilege mode.
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.
