config scheduling
Purpose Used to configure the traffic scheduling
mechanism for each COS queue.
Syntax config scheduling <class_id> [max_packet
<value>/max_latency <value>]
Description The switch contains 4 hardware priority
queues. Incoming packets must be mapped to
one of these four queues.
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 both
max_packet and max_latency parameters
are set to 0) is to empty the 4 hardware
priority queues in order − from the highest
priority queue (hardware queue 3) to the
lowest priority queue (hardware queue 0).
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.
The max_packets parameter allows you to
specify the maximum number of packets a
given hardware priority queue can transmit
before allowing the next lowest hardware
priority queue to begin transmitting its
