Scheduling

Changing the output scheduling used for the hardware queues in the Switch can customize QoS. As with any changes to QoS
implementation, careful consideration should be given to how network traffic in lower priority queues is affected. Changes in
scheduling may result in unacceptable levels of packet loss or significant transmission delay. If you choose to customize this
setting, it is important to monitor network performance, especially during peak demand, as bottlenecks can quickly develop if the
QoS settings are not suitable. In the

Configuration

folder open the

QoS

folder and click

QoS Output Scheduling

, to view the

window shown below.

Figure 6- 48. QoS Output Scheduling window

You may assign the following values to the QoS classes to set the scheduling.

Parameter Description

Max. Packets (0-255)

Specifies the maximum number of packets the above specified hardware priority queue
would be allowed to transmit before allowing the next lowest priority queue to transmit its
packets. A value between

0

and

255

can be specified.

Max. Latency (0-255)

Specifies the maximum amount of time the above specified hardware priority queue will
be allowed to transmit packets before allowing the next lowest hardware priority queue to
begin transmitting its packets. A value between

0

and

255

can be specified - with this

value multiplied by 16 ms to arrive at the total allowed time for the queue to transmit
packets. For example, a value of 3 specifies 3 X 16 = 48 ms. The queue will continue
transmitting the last packet until it is finished when the max latency timer expires.

Click

Apply

to implement changes made.

NOTE:

The settings you assign to the queues, numbers 0-7, represent the IEEE

802.1p priority tag number. Do not confuse these settings with port numbers.
