Command
History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
When you enable this command, if a Policy Map containing classification rules (ACL
and/or dscp/ ip-precedence rules) is applied to more than one physical interface
on the same port pipe, only a single copy of the policy is written (only one FP entry
is used).
NOTE: An ACL itself may still require more that a single FP entry, regardless of
the number of interfaces. For more information, refer to the “IP Access
Control Lists”, “Prefix Lists”, and “Route-map” sections in the Dell Networking
OS Configuration Guide.
test cam-usage

Version 9.0(1.3) Introduced on the S5000.
Usage
Information
This command applies to the IPv4 CAM region and is best used to verify QoS
optimization for IPv4 ACLs.
QoS Optimization for IPv4 ACLs does not impact the CAM usage for applying a
policy on a single (or the first of several) interfaces. It is most useful when a policy
is applied across multiple interfaces; it can reduce the impact to CAM usage across
subsequent interfaces.
