Usage

Information

On 40-port 10G stack-unit if the traffic is shaped between 64 and 1000 Kbs, for some values, the shaped

rate is much less than the value configured.

NOTE: When packets of size greater than 7000 bytes are expected to be received from the network,

Dell Networking recommends that you configure the burst value to be more than 175 KB if you

configured the rate shape. Such a setting ensures proper bandwidth sharing across queues.

Commands

rate-shape — shapes traffic output as part of the designated policy.

service-class bandwidth-percentage

Specify a minimum bandwidth for queues.
