Usage Information
This feature allows you to determine if the CAM has enough space available before applying the
conguration on an interface.
An input policy map with both Trust and Class-map conguration, 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 classication 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 classication rules.
Estimated CAM per
Port
Indicates the number of free CAM entries required (for the classication 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.
