Usage
Information
This feature allows you to determine if the CAM has enough space available before applying the
configuration on an interface.
An input policy map with both Trust and Class-map configuration, the Class-map rules are ignored and
only the Trust rule is programmed in the CAM. In such an instance, the 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.
