show bandwidth_control
switch number, and the highest port number of the range (also
separated by a colon) are specified. The beginning and end of the
port list range are separated by a dash. For example, 1:3 specifies
switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-
2:4 specifies all of the ports between switch 1, port 3 and switch 2,
port 4 − in numerical order. Non-contiguous portlist entries are
separated by a comma. (ex: 1:1-1:3,1:7-1:9)
Restrictions None.

To display bandwidth control settings:

config scheduling
Purpose Used to configure the traffic scheduling mechanism for each QoS queue.
Syntax
config scheduling <class_id 0-6> {max_packet <value 0-15>}
Description The Switch contains 8 hardware priority queues, one of which is internal
and not configurable. Incoming packets must be mapped to one of these
seven queues. This command is used to specify the rotation by which
these seven hardware priority queues are emptied.
The Switch’s default (if the config scheduling command is not used, or if
the config scheduling command is entered with the max_packet set to
0) is to empty the hardware priority queues in order − from the highest
priority queue (hardware queue 6) 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.
The max_packets parameter allows you to specify the maximum number
of packets a given hardware priority queue can transmit before allowing
the next lowest hardware priority queue to begin transmitting its packets.
A value between 0 and 15 can be specified. For example, if a value of 3 is
specified, then the highest hardware priority queue (number 6) will be
allowed to transmit 3 packets − then the next lowest hardware priority
queue (number 5) will be allowed to transmit 3 packets, and so on, until all
of the queues have transmitted 3 packets. The process will then repeat.
