config scheduling
Purpose Used to configure the traffic scheduling
mechanism for each COS queue.
Syntax config scheduling <class_id> [max_packet
<value>]
Description The switch contains 4 hardware priority
queues. Incoming packets must be mapped
to one of these four queues. This command
is used to specify the rotation by which
these four hardware priority queues are
emptied.
The switch’s default (if the config
scheduling command is not used, or if the
config scheduling command is entered
with max_packet set to 0) is to empty the 4
hardware priority queues in order − from
the highest priority queue (hardware queue
0) to the lowest priority queue (hardware
queue 3). Each hardware queue will
transmit all of the packets in its buffer
before allowing the next lower priority
queue to transmit its packets. When the
lowest hardware priority queue has finished
transmitting all of its packets, the highest
hardware priority queue can again transmit
any packets it may have received.
