You can set the NWA to operate in either standalone AP or managed AP mode. When the NWA is in standalone AP mode, it can serve as a normal AP, as an RF monitor to search for rouge APs to help eliminate network threats, or even as a root AP or a wireless repeater to establish wireless links with other APs in a WDS (Wireless Distribution System). A WDS is a wireless connection between two or more APs.
Your NWA’s business-class reliability, SMB features, and centralized wireless management make it ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and VLAN to provide simultaneous independent virtual APs. Additionally, innovations in roaming technology and QoS features eliminate voice call disruptions.
The NWA controls network access with Media Access Control (MAC) address filtering, and rogue Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access (WPA), WPA2 and Wired Equivalent Privacy (WEP) data encryption.

Chapter 1 Introduction
Your NWA is easy to install, configure and use. The embedded Web-based configurator enables simple, straightforward management and maintenance. See the Quick Start Guide for how to make hardware connections.
An AP controller can use Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415) to discover and configure multiple managed APs.
The NWA is a standalone AP by default. You can switch the NWA from being a standalone AP to acting as a managed AP to allow it to be managed by an AP controller, such as the NXC2500. To change between management modes, see Chapter 5 on page 49.
Table 2 NWA Management Mode Comparison

|
|
When the NWA is in standalone AP mode, the NWA is set to have a static management IP address (192.168.1.2) by default. You can use either the web configurator or FTP to upload firmware. See Section 15.3 on page 160 for more information about firmware uploading.
When the NWA is in managed AP mode, it acts as a DHCP client and obtains an IP address from the AP controller. It can be configured ONLY by the AP controller. To change the NWA back to standalone AP mode, you need to check the AP controller for the NWA’s IP address and use FTP to upload firmware for standalone AP mode.
A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access point and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In Multiple BSS (MBSSID) mode, the NWA provides multiple virtual APs, each forming its own BSS and using its own individual SSID profile.
You can configure multiple SSID profiles, and have all of them active at any one time.
You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs.
To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless network, clients can associate only with the SSIDs for which they have the correct security settings.
For example, you might want to set up a wireless network in your office where Internet telephony (VoIP) users have priority. You also want a regular wireless network for standard users, as well as a ‘guest’ wireless network for visitors. In the following figure, VoIP_SSID users have QoS priority, SSID01 is the wireless network for standard users, and Guest_SSID is the wireless network for guest users. In this example, the guest user is forbidden access to the wired Land Area Network (LAN) behind the AP and can access only the Internet.

The NWA5123-NI is equipped with dual wireless radios. This means you can configure two different wireless networks to operate simultaneously.
Note: A different channel should be configured for each WLAN interface to reduce the effects of radio interference.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music, and gaming.

In Root AP mode, the NWA (Z) can act as the root AP in a wireless network and also allow repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below, both clients A, B and C can access the wired network through the root AP.
Figure 3 Root AP Application
On the NWA in Root AP mode, you can have multiple SSIDs active for reqular wireless connections and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either

Chapter 1 Introduction
SSID to associate with the NWA in Root AP mode. A repeater must use the repeater SSID to connect to the NWA in Root AP mode.
When the NWA is in Root AP mode, repeater security between the NWA and other repeater is independent of the security between the wireless clients and the AP or repeater. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 7.2 on page 58 and Section 11.2 on page 98 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless clients and the AP. At the time of writing, repeater security is compatible with the NWA only.
The NWA can act as a wireless network repeater to extend a root AP’s wireless network range, and also establish wireless connections with wireless clients.
Using Repeater mode, your NWA can extend the range of the WLAN. In the figure below, the NWA in Repeater mode (Z) has a wireless connection to the NWA in Root AP mode (X) which is connected to a wired network and also has a wireless connection to another NWA in Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated wireless clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP throught repeaters Z and Y.
Figure 4 Repeater Application
When the NWA is in Repeater mode, repeater security between the NWA and other repeater is independent of the security between the wireless clients and the AP or repeater. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 7.2 on page 58 and Section 11.2 on page 98 for more details.
Once the security settings of peer sides match one another, the connection between devices is made.

Chapter 1 Introduction
At the time of writing, repeater security is compatible with the NWA only.
You can use the following ways to manage the NWA.
Web Configurator
The Web Configurator allows easy NWA setup and management using an Internet browser. This User’s Guide provides information about the Web Configurator.
Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the NWA. You can access it using remote management (for example, SSH or Telnet). See the Command Reference Guide for more information.
File Transfer Protocol (FTP)
This protocol can be used for firmware upgrades and configuration backup and restore.
Simple Network Management Protocol (SNMP)
The NWA can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.
Do the following things regularly to make the NWA more secure and to manage it more effectively.
•Change the password often. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.
•Write down the password and put it in a safe place.
•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NWA to its factory default settings. If you backed up an earlier configuration file, you won’t have to totally re-configure the NWA; you can simply restore your last configuration.
See your Quick Start Guide for information on making hardware connections.

Chapter 1 Introduction
Always use Maintenance > Shutdown or the shutdown command before you turn off the NWA or remove the power. Not doing so can cause the firmware to become corrupt.
Table 4 Starting and Stopping the NWA
METHOD |
DESCRIPTION |
Turning on the power |
A cold start occurs when you turn on the power to the NWA. The NWA powers up, |
|
checks the hardware, and starts the system processes. |
|
|
Rebooting the NWA |
A warm start (without powering down and powering up again) occurs when you use |
|
the Reboot button in the Reboot screen or when you use the reboot command. The |
|
NWA writes all cached data to the local storage, stops the system processes, and then |
|
does a warm start. |
|
|
Using the RESET |
If you press the RESET button on the back of the NWA, the NWA sets the |
button |
configuration to its default values and then reboots. See Section 19.6 on page 175 for |
|
more information. |
