Estimated CAM output column contains the size of the CAM space required for the
Trust rule and not the Class-map rule.
The following describes the test cam-usage service-policy input policy-
map stack-unit command shown in the following example.
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, 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 stack-unit/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,
