config scheduling_mechanism
Purpose
Syntax
Description
Used to configure the scheduling mechanism for the QoS function
config scheduling mechanism [strict | weight_fair]
The config scheduling_mechanism command allows the user to
select between a Weight Fair (WRR) and a Strict mechanism for
emptying the priority classes of service of the QoS function. The
Switch contains seven hardware priority classes of service.
Incoming packets must be mapped to one of these seven
hardware priority classes of service. This command is used to
specify the rotation by which these seven hardware priority classes
of service are emptied.
The Switch's default is to empty the seven priority classes of
service in order − from the highest priority class of service (queue
6) to the lowest priority class of service (queue 0). Each queue will
transmit all of the packets in its buffer before allowing the next
lower priority class of service to transmit its packets. Lower classes
of service will be pre-empted from emptying its queue if a packet is
received on a higher class of service. The packet that was
received on the higher class of service will transmit its packet
