The following table describes the labels in this screen.

Table 36 Network > Wireless LAN > QoS

LABEL DESCRIPTION

WMM QoS Policy Select Default to have the NBG420N automatically give a service a

priority level according to the ToS value in the IP header of packets

it sends. WMM QoS (Wifi MultiMedia Quality of Service) gives high

priority to voice and video, which makes them run more smoothly.

Select Application Priority from the drop-down list box to display a

table of application names, services, ports and priorities to which

you want to apply WMM QoS.

The table appears only if you select Application Priority in WMM

QoS Policy.

# This is the number of an individual application entry.

Name This field displays a description given to an application entry.

Service This field displays either FTP, WWW, E-mail or a User Defined

service to which you want to apply WMM QoS.

Dest Port This field displays the destination port number to which the

application sends traffic.

Priority This field displays the priority of the application.

Highest - Typically used for voice or video that should be high-

quality.

High - Typically used for voice or video that can be medium-quality.

Mid - Typically used for applications that do not fit into another

priority. For example, Internet surfing.

Low - Typically used for non-critical “background” applications,

such as large file transfers and print jobs that should not affect

other applications.

Modify Click the Edit icon to open the Application Priority Configuration

screen. Modify an existing application entry or create a application

entry in the Application Priority Configuration screen.

Click the Remove icon to delete an application entry.

Apply Click Apply to save your changes to the NBG420N.
