Configuring a SonicPoint NDR Profile

You can add any number of SonicPoint NDR profiles. The specifics of the configuration will vary slightly depending on which 802.11 protocols you select.

To configure a SonicPoint NDR provisioning profile:
1
Navigate to SonicPoint > SonicPoints page.
2
To add a new SonicPoint NDR profile, click the Add SonicPoint NDR Profile button in the SonicPoint N Provisioning Profiles table. To edit an existing profile, select the profile and click the Configure icon in the same line as the profile you want to edit. The Add/Edit SonicPoint NDR Profile dialog displays.

You configure the SonicPoint NDR through options on these tabs:

General Tab

In the General tab, configure the desired settings:

SonicPoint Settings section
1
Check Enable SonicPoint to enable each SonicPoint NDR automatically when it is provisioned with this profile. This option is selected by default.
2
Optionally, check Retain Settings to have the SonicPoint NDRs provisioned by this profile retain customized settings until system restart or reboot. This option is not selected by default.

If you select this option, the Edit button becomes active and the Retain Settings dialog displays. To specify the settings to retain:

a
If you are editing an existing SonicPoint NDR profile, click the Edit button. The Retain Settings dialog displays.

802.11n Radio 0 Settings and 802.11n Radio 1 Settings section

1
Check the Enable Radio check box to automatically enable the 802.11n radio bands on all SonicPoint NDRs provisioned with this profile. This option is selected by default.
From the Enable Radio drop-down menu, select a schedule for when the 802.11n radio is on or create a new schedule; default is Always on. You can create a new schedule by selecting Create new schedule.
2
Select your preferred radio mode from the Mode drop-down menu. The wireless security appliance supports the modes shown in Mode Options.
 

Mode Options

802.11n Radio 0

802.11n Radio 1

 

5GHz 802.11n Only

2.4GHz 802.11n Only

Allows only 802.11n clients access to your wireless network. 802.11a/b/g clients are unable to connect under this restricted radio mode.

5GHz 802.11n/a Mixed

2.4GHz 802.11n/g/b Mixed

Supports 802.11a and 802.11n (Radio 0) or 802.11b, 802.11g, and 802.11n (Radio 1) clients simultaneously. If your wireless network comprises multiple types of clients, select this mode. This is the default.

5GHz 802.11a Only

 

Select this mode if only 802.11a clients access your wireless network.

 

2.4GHz 802.11g Only

If your wireless network consists only of 802.11g clients, you may select this mode for increased 802.11g performance. You may also select this mode if you wish to prevent 802.11b clients from associating.

TIP: For 802.11n clients only, for optimal throughput speed solely, SonicWall recommends the 802.11n Only radio mode. Use the 802.11n/b/g Mixed radio mode for multiple wireless client authentication compatibility.
NOTE: The available 801.11n Radio 0/1 S.ettings options change depending on the mode selected. If the wireless radio is configured for a mode that:
Supports 802.11n, the following options are displayed: Radio Band, Primary Channel, Secondary Channel, Enable Short Guard Interval, and Enable Aggregation.
Does not support 802.11n, only the Channel option is displayed.
3
Optionally, select Enable DFS Channels to enable the use of Dynamic Frequency Selection (DFS), which allows wireless devices to share the same spectrum with existing radar systems within the 5 GHz band.
NOTE: If you select this option, choose either Standard - 2MHz Channel or Wide - 40 MHz Channel as the Radio Band. The Primary Channel and Standard Channel drop-down menus then display a choice of available sensitive channels.
NOTE: This option only appears on the 802.11n Radio 0 tab as the 802.11n Radio 1 does not have a wireless speed connection mode of at least 5 GHz.
4
In the SSID field, enter a recognizable string for the SSID of each SonicPoint NDR using this profile. This is the name that will appear in clients’ lists of available wireless connections.
5
Does not support 802.11n, select a channel from the Channel drop-down menu.
Auto - Allows the appliance to automatically detect and set the optimal channel for wireless operation based on signal strength and integrity. This is the default setting. Use Auto unless you have a specific reason to use or avoid specific channels.
Specific channel – You can select a single channel within the range of your regulatory domain. Selecting a specific channel also can help with avoiding interference with other wireless networks in the area.

7
For (802.11n only): from the Radio Band drop-down menu, select the band for the 802.11n radio:
Auto - Allows the appliance to automatically detect and set the optimal channel for wireless operation based on signal strength and integrity. Both the Primary Channel and Secondary Channel are set to Auto also. This is the default setting.
Standard - 20 MHz Channel—Specifies that the 802.11n radio will use only the standard 20 MHz channel. When this option is selected, the Standard Channel drop-down menu is displayed instead of the Primary Channel and Secondary Channel options.
Standard Channel—This drop-down menu only displays when the 20 MHz channel is selected. By default, this is set to Auto, which allows the appliance to set the optimal channel based on signal strength and integrity.

Optionally, you can select a single channel within the range of your regulatory domain. Selecting a specific a channel can also help with avoiding interference with other wireless networks in the area. The available channels depend on which Radio you are configuring:

Wide - 40 MHz Channel—Specifies that the 802.11n radio will use only the wide 40 MHz channel. When this option is selected, the Primary Channel and Secondary Channel drop-down menus are active:
Primary Channel—By default this is set to Auto. Optionally, you can specify a specific primary channel. The available channels are the same as for 802.11a in Step 5.
Secondary Channel—Is set to Auto regardless of the setting of Primary Channel.
8
Enable Short Guard Interval—Specifies the short guard interval of 400ns (as opposed to the standard guard interval of 800ns).
NOTE: This option is not available if 5GHZ 802.11a Only or 2.4GHz 802.11g Only mode is selected.

A guard interval is a set amount of time between transmissions that is designed to ensure distinct transmissions do not interfere with one another. The guard interval introduces immunity to propagation delays, echoes, and reflections. An AP identifies any signal content received inside this interval as unwanted inter-symbol interference, and rejects that data. The guard interval is a pause in transmission intended to avoid data loss from interference or multipath delays.

The 802.11n standard specifies two guard intervals: 400ns (short) and 800ns (long).

Enabling a short guard interval can decrease network overhead by reducing unnecessary idle time on each AP. A short guard interval of 400 nanoseconds (ns) will work in most office environments as distances between points of reflection, as well as between clients, are short. Most reflections will be received quickly. The shorter the guard interval, the more efficiency there is in the channel usage, but a shorter guard interval also increases the risk of interference

Some outdoor deployments may, however, require a longer guard interval. The need for a long guard interval of 800 ns becomes more important as areas become larger, such as in warehouses and in outdoor environments, as reflections and echoes become more likely to continue after the short guard interval would be over.

The guard interval is a pause in transmission intended to avoid data loss from interference or multipath delays and increase 802.11n data rate. Ensure the wireless client also can support a short guard interval to avoid compatibility issues.

9
Select Enable Aggregation to enable 802.11n frame aggregation, which combines multiple data frames in a single transmission to reduce overhead and increase throughput.
NOTE: This option is not available if 5GHZ 802.11a Only or 2.4GHz 802.11g Only mode is selected.

Data over wireless networks are sent as a stream of packets known as data frames. Frame aggregation takes these packets and combines them into fewer, larger packets, thereby allowing an increase in overall performance. Frame aggregation was added to the 802.11n specification to allow for an additional increase in performance. Frame aggregation is a feature that only 802.11n clients can take advantage of, as legacy systems will not be able to understand the new format of the larger packets.

Ensure the wireless client also can support aggregation to avoid compatibility issues.

TIP: The Enable Short Guard Interval and Enable Aggregation options can slightly improve throughput. They both function best in optimum network conditions where users have strong signals with little interference. In networks that experience less than optimum conditions (interference, weak signals, etc.), these options may introduce transmission errors that eliminate any efficiency gains in throughput.
10
The Enable MIMO option enables/disables MIMO (multiple-input multiple output). Enabling this option increases 802.11n throughput by using multiple-input/multiple-output antennas. This option is enabled by default for all 802.11n modes and is dimmed to ensure it is not disabled. The option is activated and selected by default if 5GHZ 802.11a Only or 2.4GHz 802.11g Only mode is selected.
Wireless Security section
NOTE: If a VAP was selected in the 802.11n Radio Virtual AP Group drop-down menu on the Settings tab, this section is not available. Instead, the Virtual Access Point Encryption Settings section is displayed. Go to Virtual Access Point Encryption Settings Section.

The options change depending on the authentication type you select.

The Wireless Security sections of both 802.11n Radio 0 and 802.11n Radio 1 tabs are the same as for the SonicPoint N 802.11n Radio tab. For how to configure the Wireless Security settings, see Wireless Security section.
