8.4.1 Adding a QoS Queue

Click the QoS Queue Setup screen’s Add button to configure a new queue.

Figure 47 QoS Queue Setup: Add

The following table describes the labels in this screen.

Table 41 QoS Queue Setup: Add

LABEL DESCRIPTION

Name Enter the descriptive name of this queue.

Enable Enable or disable this queue.

Interface Select the interface to which this queue is applied.

Queue

Precedence

Select the precedence level (from 1 to 8) of this queue. The smaller the number, the higher

the priority level. Traffic assigned to higher priority queues gets through faster while traffic

in lower priority queues is dropped if the network is congested.

The precedence list shows the scheduler algorithm for each precedence level. The scheduler

algorithm depends on the interface. Ethernet interfaces use strict priority (SP). ATM and

PTM interfaces use the scheduler algorithm configured for the interface (weighted round

robin or weighted fair queuing).

The VDSL Router uses the algorithm to service queues with the same precedence.

The VDSL Router uses strict priority to service queues with different precedences.
