Service Manual

Field Description
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, cannot 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.
NOTE: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed; therefore, the output contains only
L2ACL CAM partition entries.
Example
Dell# 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,
