Usage Information

If traffic is shaped between 64 and 1000 Kbs, for some values, the shaped rate is much less than the value configured.

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 EMC 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.
