config scheduling_mechanism
Purpose Used to configure the scheduling mechanism for the QoS function
Syntax
config scheduling_mechanism [strict | weight_fair]
Description
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 before allowing the lower class to resume clearing its queue.
Parameters
strict – Entering the strict parameter indicates that the highest class of
service is the first to be processed. That is, the highest class of service
should finish emptying before the others begin.
weight_fair – Entering the weight fair parameter indicates that the priority
classes of service will empty packets in a weighted round-robin (WRR)
order. That is to say that they will be emptied in an even distribution.
Restrictions Only administrator-level users can issue this command.
Example usage:
To configure the traffic scheduling mechanism for each COS queue:
DGS-3324SRi:4#config scheduling_mechanism strict
Command: config scheduling_mechanism strict
Success.
