SMCD3GN2 Wireless Cable Modem User Manual

By default, the Gateway uses strict priority. To change to weighted priority:

1. For

Queue Type

, select

Weighted Priority

. The options in Figure 28 appear.

Figure 28. Weighted Priority Options

2. For

Weight Base

, select a queue weight to ensure that some sets of queues get higher

thresholds than others. Queue weight directs the Gateway to set the queue thresholds

proportionately. Choices are

8

or

10

. Queues with a weight of 10 are longer than those with

a queue weight of 8.

3. For each Gateway queue, enter a weight. Each weight corresponds to a percentage of

consumed bandwidth, as shown in the

% of Bandwidth

column.

Option

Description

Dscp remarking mode

Lets you select the DSCP remarking mode that the Gateway is to use. Choices are:

•

Map frame priority to AF code points = select this option for Quality of Service configurations that use

assured forwarding (AF) code points to mark packets. AF guarantees a certain amount of bandwidth to

an AF class and allows access to extra bandwidth, if available. (

default

)

•

Map frame priority to CS code points = select this option for Quality of Service configurations that use

class selector (CS) code points to mark packets. CS provides code points that can be used for

backward compatibility with IP Precedence. IP Precedence is a legacy technology that the Gateway

supports for backwards compatibility.

Request a remarking action when DSCP equals one of the following CPs

Expedited Forwarding

Code Point

Expedited forwarding provides a low-loss, low-latency, low-jitter, and assured bandwidth service.

Applications such as VoIP, video, and other time sensitive applications require a robust network treatment

like expedited forwarding. When checked, the Gateway requests a remarking action if DSCP equals an

expedited forwarding code point. By default, this option is not checked.

Assured Forwarding

Code Points

Assured forwarding defines a method by which packets can be given different forwarding assurances.

Traffic can be divided into different classes and then each class given a certain percentage of bandwidth.

For example, one class could have 50% of the available link bandwidth, another class could have 30%,

and another 20% of the bandwidth. When checked, the Gateway requests a remarking action if DSCP

equals an assured forwarding code point. By default, this option is not checked.

Class Selector Code

Points

Class Selector code points are code points that can be used for backward compatibility with IP Precedence

models. When checked, lets the Gateway request a remarking action if DSCP equals a class selector code

point. By default, this option is checked, but does not take effect until the OSPF Status changes to

ENABLE.

Zero

When checked, lets the Gateway request a remarking action if DSCP equals zero. By default, this option is

checked, but does not take effect until the OSPF Status changes to ENABLE.

Others

When checked, lets the Gateway request a remarking action if DSCP equals a non-zero value. By default,

this option is checked, but does not take effect until the OSPF Status changes to ENABLE.

ENABLE = Gateway’s wireless operation is active. Selecting this option activates the options in this

menu. Clicking

DISABLE = Gateway’s wireless operation is not active. Selecting this option deactivates the options in

this menu. Clicking

Wireless Mode

If wireless operation is enabled for the Gateway, this option selects the wireless mode used by the

Gateway. Choices are:

•

11B/G Mixed = use this setting if you have a combination of IEEE 802.11b and IEEE 802.11g devices

on your network.

•

11B Only = use this setting if you have only IEEE 802.11b devices on your network or want to limit your

network to IEEE 802.11b devices.

•

11G Only = use this setting if you have only IEEE 802.11g devices on your network or want to limit your

network to IEEE 802.11g devices.

•

11N Only = use this setting if you have only IEEE 802.11n devices on your network or want to limit your

network to IEEE 802.11n devices.

•

11G/N Mixed = use this setting if you have a combination of IEEE 802.11g and IEEE 802.11n devices

on your network.

•

11B/G/N Mixed = use this setting if you have a combination of IEEE 802.11b, IEEE 802.11g, and IEEE

802.11n devices on your network. (

default

)

SSID setting

SSID is the network name shared among all devices in a wireless network. The SSID must be identical for

all devices in the wireless network. It is case-sensitive and must not exceed 32 alpha-numeric characters,

which may be any keyboard character. Be sure this setting is the same for all devices in your wireless

network.

Primary SSID

The primary SSID can be hidden or configured for Wi-Fi Multimedia (WMM) mode.

•

Hidden = when checked, hides the SSID. Use this setting to block illegal connections. Users cannot

reconnect automatically or manually to a wireless network that uses a hidden SSID. The wireless

network that uses a hidden SSID does not appear in the Microsoft Windows Wireless Network

Connection window.

•

In-service = when checked, broadcasts the Gateway’s SSID.

•

WMM Mode = when checked, enables WMM. Enabling WMM can help control latency and jitter when

transmitting multimedia content over a wireless connection.

Channel

Select the appropriate channel from the list provided to correspond with your network settings, between 1

and 11 (in North America). Default is Auto, which selects the appropriate channel automatically. All devices

in your wireless network must use the same channel to work properly.
