Example usage:
To configure traffic scheduling:
D E S - 6 5 0 0 : 4 # c o n f i g s c h e d u l i n g 0 m a x _ p a c k e t 1 5
C o m m a n d : c o n f i g s c h e d u l i n g 0 m a x _ p a c k e t 1 5
S u c c e s s .
D E S - 6 5 0 0 : 4 #
Example usage:
To configure a Combination Queue with a Class 6 priority class with strict priority and the remaining classes as
weighted round robin (WRR) scheduling:
D E S - 6 5 0 0 : 4 # c o n f i g s c h e d u l i n g 6 m a x _ p a c k e t 0
C o m m a n d : c o n f i g s c h e d u l i n g 6 m a x _ p a c k e t 0
S u c c e s s .
D E S - 6 5 0 0 : 4 #
method of forwarding packets — as long as the priority classes with a
0 in their max_packet field are empty. When a packet arrives in a
priority class with a 0 in its max_packet field, this class will
automatically begin forwarding packets until it is empty. Once a priority
class with a 0 in its max_packet field is empty, the remaining priority
classes will reset the weighted round-robin (WRR) cycle of forwarding
packets, starting with the highest available priority class. Priority
classes with an equal level of priority and equal entries in their
max_packet field will empty their fields based on hardware priority
scheduling.
<class_id 0-6>  Specifies to which of the seven hardware priority
classes the config scheduling command will be applied. The seven
priority classes are identified by number  from 0 to 6  with queue 6
being the highest priority.
max_packet <value 0-15>  Specifies the maximum number of
packets the above specified priority class will be allowed to transmit
per weighted round-robin (WRR) cycle. A value between 0 and 15
packets can be specified. A zero (0) denotes strict priority scheduling
for that priority class.
Only Administrator-level users can issue this command.
NOTICE: The default QoS scheduling arrangement is a strict priority
schedule. To customize scheduling to set up weighted or round-robin class
clearing, the max_packets values need to be changed.
