Example usage:
To configure the traffic scheduling mechanism for each queue:
DES-3200-28:4# config scheduling 0 weight 55
Command: config scheduling 0 weight 55
Success.
DES-3200-28:4#
Used to configure the traffic scheduling mechanism for each COS
queue.
config scheduling <class_id 0-3> weight <value 1-55>
The Switch contains four hardware priority queues. Incoming packets
must be mapped to one of these four queues. This command is used to
specify the rotation by which these four hardware priority queues are
emptied.
The Switch's default (if the config scheduling command is not used) is
to empty the four hardware priority queues in order  from the highest
priority queue (hardware queue 3) to the lowest priority queue
(hardware queue 0). Each hardware queue will transmit all of the
packets in its buffer before allowing the next lower priority queue to
transmit its packets. When the lowest hardware priority queue has
finished transmitting all of its packets, the highest hardware priority
queue can again transmit any packets it may have received.
weight <value 1-55>  Specifies the weights for weighted COS
queuing. A value between 1 and 55 can be specified.
<class_id 0-3>  This specifies which of the four hardware priority
queues the config scheduling command will apply to. The four
hardware priority queues are identified by number  from 0 to 3  with
the 0 queue being the lowest priority.
Only Administrator-level users can issue this command.
