DES-30XX Layer 2 Switch CLI Reference Manual
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 four hardware priority classes of service. Incoming
packets must be mapped to one of these four hardware priority
classes of service. This command is used to specify the rotation by
which these four hardware priority classes of service are emptied.
The Switch's default is to empty the four priority classes of service
in order − from the highest priority class of service (queue 3) 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
highest class of service will transmit its packet before allowing the
lower class to resume clearing its queue.
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.
Other classes of service will follow weight fair scheduling.
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.
Only administrator-level users can issue this command.
Used to display the current traffic scheduling mechanisms in use

mechanism in use on the Switch.
