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.
4. When you finish, click

DSCP Remarking Menu
The DSCP Remarking menu lets you configure the Gateway’s DSCP remarking mode and
actions.
To access the Queue Settings menu, click
QOS
in the menu bar and then click the
DSCP
Remarking
submenu in the menu bar. Figure 29 shows an example of the menu.
Note:
The
DSCP Remarking
submenu is not available in the menu bar if
Enable QOS
Module
is not checked in the QoS Settings menu (see page 39).

Table 8. DSCP Remarking Options
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.

Option
Description
Wireless ON/OFF
Enables or disables the Gateway’s wireless operation.
•
ENABLE = Gateway’s wireless operation is active. Selecting this option activates the options in this
menu. Clicking
Apply
displays the submenus below the Wireless menu.
•
DISABLE = Gateway’s wireless operation is not active. Selecting this option deactivates the options in
this menu. Clicking
Apply
hides the submenus below the Wireless menu. (
default
)
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.
