QOS Commands

config scheduling

packets. A value between 0 and 255 can be

specified. For example, if a value of 3 is

specified, then the highest hardware priority

queue (number 3) will be allowed to transmit 3
packets

−

then the next lowest hardware

priority queue (number 2) will be allowed to

transmit 3 packets, and so on, until all of the

queues have transmitted 3 packets. The

process will then repeat.

The

max_latency

parameter allows you to

specify the maximum amount of time that

packets are delayed before being transmitted.

for a given hardware priority que. A value

between 0 and 255 can be specified. This

number is then multiplied by 16 ms to

determine the maximum latency. For

example, if 3 is specified, the maximum

latency allowed will be 3 X 16 = 48 ms.

When the specified hardware priority queue

has been waiting to transmit packets for this

amount of time, the current queue will finish

transmitting its current packet, and then allow

the hardware priority queue whose

max_latency timer has expired to begin

transmitting packets.

Parameters

<class_id>

−

This specifies which of the four

hardware priority queues the

config

scheduling

command will apply to. The four

hardware priority queues are identified by
number

−

from 0 to 3

−

with the 0 queue being

the lowest priority.

max_packet <value>

−

Specifies the maximium
