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 text 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.
