QoS Settings Menu

Quality of Service (QoS) refers to a collection of techniques for identifying data whose

delivery across the network is time sensitive, and managing its delivery through both

bandwidth allocation and prioritization schemes

Using the QoS Settings menu, you can enable the Gateway’s QoS module to provide

guarantees on the ability of the network to deliver predictable results. To access the QoS

menu, click

QOS

in the menu bar. Figure 23 shows an example of the menu.

By default, QoS is enabled. To disable the Gateway’s QoS module, uncheck

Enable QOS

Module

and click

Apply

. To disable the Gateway’s QoS module, uncheck

Enable QOS

Module

and click

Apply

.

When the Gateway’s QoS module is enabled, the following submenus appear under

QOS

in

the menu bar:

y

Port

- lets you configure the priority queue to which the switch port is mapped. See page

45.

y

COS

- lets you define four queues to which the CoS is mapped. See page 46.

y

DSCP

- lets you define the QoS class queue to which the customized DSCP is mapped.

See page 48.

y

Queue

- lets you specify whether QoS behavior runs with strict or weighted priority. See

page 50.

y

DSCP

Remarking

- lets you define the DSCP remarking action and mode. See page 52.
