Example usage:
To show the scheduling mechanism:
The co nfig scheduling_mechanism command configures the
scheduling mechanism for the QoS function. It allows the user to
select between a round robin (WRR) and a strict mechanism for
emptying the priority classes of service of the QoS function. The
Switch contains four h
packets must be map
classes of service, or queues. This command is used to specify the
rotation b y which these four hardware priority queues are emptied.
The Switch's default is to empty the four hardware priority queues in
order − from the highest priority hardware queue (class 3) to the
lowest pri ority hardware queue (class 0). Each queue will transmit all
of the pa ckets in its buffer before allowing the next lower priority
que ue to transmit its packets. A lower priority hardware queue will
be pre-empted from emptying its queue if a packet is received on a
hig her priority hardware queue. The packet that was received on the
hig her priority hardware queue will transmit its packet before
allo wing the lower priority hardware queue to resume clearing its
que ue.
ass_id 0-3> – This specifies to which of the four hardware
<cl
cla sses of service the config scheduling_mechanism command
app lies. The four hardware classes of service are identified by
num ber (from 0 to 3), with the 0 queue having the lowest priority.
ct – Specifies that the highest class of service is the first to be
stri
pro cessed. That is, the highest class of service should finish
em ptying before the others begin.
nd_robin – Specifies that the priority classes of service are to
rou
em pty packets in a weighted roundrobin (WRR) order, or in an even
dis tribution.
Only administrator-level users can issue this command.
