config scheduling 
Purpose  To configure traffic scheduling for each of the Switch’s QoS queues.
Syntax 
config scheduling <class_id 0-3> max_packet <value 0-15> 
Description The config scheduling command configures traffic scheduling for 
each of the Switch’s QoS queues. 
The Switch contains four hardware classes of service. Incoming 
packets must be mapped to one of these four hardware queues. 
This command is used to specify the rotation by which these four
