config scheduling
next lowest priority queue to begin transmitting
its packets. A value between 0 and 255 packets
can be specified. For example, if a value of 5 is
specified, then the highest priority queue (queue
3) will be allowed to transmit 5 packets. Then
the next lower priority queue (queue 2) will be
allowed to transmit 5 packets, and so on, until
all of the queues have transmitted 5 packets.
The process will then repeat.
The max_latency parameter allows you to
specify the maximum amount of time that
packets will be delayed before being
transmitted. For a given priority queue, a value
between 0 and 255 can be specified. This
number is then multiplied by 16 milliseconds to
determine the maximum allowed latency. For
example, if 3 is specified for queue 3, the
maximum latency allowed will be 3 X 16 ms =
48 ms. When queue 3 has been waiting to
transmit packets for longer than 48 ms, the
currently transmitting priority queue is allowed to
finish transmitting its current packet, and then
queue 2 is allowed to begin transmitting its
packets.
Parameters
<class_id> − Specifies which of the four priority
queues the config scheduling command will
be applied to. The four priority queues are
identified by number − from 0 to 3 − with queue
3 being the highest priority.
max_packet <value 0-255> − Specifies the
maximum number of packets the above
specified priority queue will be allowed to
transmit before allowing the next lowest priority
queue to transmit its packets. A value between
0 and 255 packets can be specified. The default
value is 0.
