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 22 shows an example of the menu.
By default, QoS is disabled. To enable the Gateway’s QoS module, check
Enable QOS
Module
and click
Apply
. To disable the Gateway’s QoS module, uncheck
Enable QOS
Module
and click
Apply
.
If you enable the Gateway’s QoS module, the following submenus appear under
QOS
in the
menu bar:
!
Port
- lets you configure the priority queue to which the switch port is mapped. See page
42.
!
COS
- lets you define four queues to which the CoS is mapped. See page 43.
!
DSCP
- lets you define the QoS class queue to which the customized DSCP is mapped.
See page 45.
!
Queue
- lets you specify whether QoS behavior runs with strict or weighted priority. See
page 46.
!
DSCP
Remarking
- lets you define the DSCP remarking action and mode. See page 48.
