Entering a 0 into the <value 0-15> field of the max_packet parameter allows for the creation of a
Combination Queue for the forwarding of packets.This Combination Queue allows for a combination
of strict and weight-fair (weighted round-robin “WRR”) scheduling. Priority classes that have a 0 in the
max_packet field will forward packets with strict priority scheduling.The remaining classes, that do not have a 0
in their max_packet field, will follow a weighted round-robin (WRR) 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.
Parameters <class_id 0-6> – Specifies which of the seven hardware priority classes the config scheduling command will
be applied to.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.
Restrictions Only administrator-level users can issue this command.
Note: 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.
