instance, the Estimated CAM output column will contain the size of the CAM space
required for the Trust rule and not the Class-map rule.
The following describes output from the text cam-usage service-policy
input policy-map stack-unit command shown in the Example below.
Field Description
Stack-Unit Indicates the stack-unit 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, can not 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

For a L2 Input Policy Map pmap_l2, the output must be as
follows,
Stack-| Portpipe| CAM Partn| Avail CAM| Est CAM/Port| Status
