Defines a control for one or more existing classifiers on a Multilayer
Switching Module.

Important Considerations

■

A

control

can assign multiple rate limit values and an IEEE 802.1p

priority tag value to the packets that are associated with one or more
classifiers.

■

The module prompts you according to the rate limit type that you
select. You can only use one rate limit type (

none

,

receivePort

, or

aggregate

) per control. For a type of

receivePort

or

aggregate

,

you can specify multiple rate-limit values for groups of ports or
individual ports. The

aggregate

rate limit type can only be applied

to flow classifiers.

■

Loss-eligible packets

are conforming packets that are discarded

instead of queued when transmit queues back up beyond a threshold.
You can specify whether conforming packets (as well as
nonconforming excess packets) are loss eligible when you define the
control. Marking packets loss eligible is useful for an intelligent discard
of traffic in a congestion situation. Nonconforming excess packets are
packets that exceed the specified rate limit.

■

With the QoS timer control, you can configure QoS control sessions
with starting and ending times (similar to using a VCR).
