Deficit Weighted Round Robin (DWRR) is used on the other queues with the following

weights:

3.10.13.1.4 — QoS with jumbo frame

While there is no physical limitation to the number of ports that can receive jumbo frame,

if to many jumbo flows are transmitted toward the same port into two different queues the

QoS could work in wrong way. It is recommended to forward jumbo frame only in queue

Q1 (lower priority).

3.10.13.2 — QoS in the MPT

Figure 3.73 and Figure 3.74 shows an overview of the QoS implementation inside the

MPT.
