Usage
Information
This features 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 will contain the size of the CAM space required for the Trust
rule and not the Class-map rule.
threshold
e
Specify the minimum and maximum threshold values for the configured WRED profiles.
Syntax
threshold min number max number
To remove the threshold values, use the no threshold min number max number command.
Note: In a Layer 2 Policy Map, IPv4/IPv6 rules are not allowed and hence the output
contains only L2ACL CAM partition entries.
Table 42-7. test cam-usage Command Example Fields
Field Description
Linecard Indicates the line card 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, 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 linecard/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.
