CHAPTER 1
Introduction
1.1 Overview
Your NWA3000-N series AP’s business-class reliability, SMB features, and
centralized wireless management make it ideally suited for advanced service
delivery in mission-critical networks. The NWA3000-N series AP provides secure
mobility across the 2.4GHz and 5GHz spectrums and the IEEE 802.11n standard’s
high bandwidth to support high-performance applications. It uses Multiple BSSID
and VLAN to provide up to eight simultaneous independent virtual APs.
Additionally, innovations in roaming technology and QoS features eliminate voice
call disruptions. It can serve as an AP, Bridge, Repeater or even as an RF monitor
to search for rouge APs to help eliminate network threats.
The NWA3000-N series AP controls network access with Media Access Control
(MAC) address filtering, rogue Access Point (AP) detection and containment, and
an internal authentication server. 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.
A NWA3000-N series AP can manage up to 24 other NWA3000-N series APs on
your network. Configuration profiles let you easily use different WLAN and s ecurity
settings for various virtual and managed APs.
Your NWA3000-N series AP 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.

Chapter 1 Introduction
1.2 Applications for the NWA3000-N series AP
The NWA3000-N series AP can be configured to use the following operat ing modes
•Bridge / Repeater
•AP + Bridge
•MBSSID
Applications for each operating mode are shown below.
Note: A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
1.2.1 Bridge / Repeater
The NWA3000-N series AP can act as a wireless network bridge and establish
wireless links with other APs. In the figure below, the two NWA3000-N series APs
(A and B) are connected to independent wired networks and have a bridge
connection (A can communicate with B) at the same time. A NWA3000-N series AP
in repeater mode (C) has no Ethernet connection. When the NWA3000-N series AP
is in bridge mode, you should enable Spanning Tree Protocol (STP) to prevent
bridge loops.
When the NWA3000-N series AP is in Bridge / Repeater mode, security between
APs (the Wireless Distribution System or WDS) is independent of the security
between the wireless stations and the AP. If you do not enable WDS security,
traffic between APs is not encrypted. When WDS security is enabled, both APs
must use the same pre-shared key.
Once the security settings of peer sides match one another, the connection
between devices is made.

Chapter 1 Introduction
At the time of writing, WDS security is compatible with other ZyXEL access points
only. Refer to your other access point’s documentation for details.

1.2.1.1 Bridge / Repeater Mode Example
In the example below, when both NWA3000-N series APs are in Bridge/Repeater
mode, they form a WDS (Wireless Distribution System) allowing the computers in
LAN 1 to connect to the computers in LAN 2.
Figure 3 Bridging Example
Be careful to avoid bridge loops when you enable bridging in the NW A3000-N
series AP. Bridge loops cause broadcast traffic to circle the network endlessly,
resulting in possible throughput degradation and disruption of communications.
The following examples show two network topologies that can lead to this
problem:

• If two or more NWA3000-N series APs (in bridge mode) are connected to the
same hub.
Figure 4 Bridge Loop: Two Bridges Connected to Hub
• If your NWA3000-N series AP (in bridge mode) is connected to a wired LAN
while communicating with another wireless bridge that is also connected to the
same wired LAN.
Figure 5 Bridge Loop: Bridge Connected to Wired LAN
To prevent bridge loops, ensure that you enable Spanning Tree Protocol (STP) in
the Wireless screen or your NW A3000-N series AP is not set to bridge mode while
connected to both wired and wireless segments of the same LAN.

1.2.2 AP + Bridge
In AP + Bridge mode, the NWA3000-N series AP supports both AP and bridge
connection at the same time.
In the figure below, A and B use X as an AP to access the wired network, while X
and Y communicate in bridge mode.
When the NWA3000-N series AP is in AP + Bridge mode, security between APs
(WDS) is independent of the se cu ri ty be tween the wireless stations and the AP. If
you do not enable WDS security, tr affi c between APs is not encrypted. When WDS
security is enabled, both APs must use the same pre-shared key.
Unless specified, the term “security settings” refers to the traffic between the
wireless stations and the NWA3000-N series AP.

1.2.3 MBSSID
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

NWA3000-N Series User’s Guide
NWA3000-N series AP provides multiple virtual APs, each forming its own BSS and
using its own individual SSID profile.
You can assign different wireless and security settings to each SSID profile. This
allows you to compartmentalize groups of users, set v arying 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.
See Section 4.1 on page 55 for an example of using MBSS.
1.3 Management Mode
One NWA3000-N series AP uses Control And Provisioni ng of Wireless Access Points
(CAPWAP, see RFC 5415) to allow one AP to configure and manage up to 24
others. This centralized management can greatly reduce the effort of setting up
and maintaining multiple devices.

1.5 Good Habits for Managing the NWA3000-N series AP
Do the following things regularly to make the NWA3000-N series AP 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.
NWA3000-N Series User’s Guide
25
Chapter 1 Introduction
• 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 y our password, you will hav e to reset the
NWA3000-N series AP to its factory default settings. If you back ed up an earl ier
configuration file, you won’t have to totally re-configure the NWA3000-N series
AP; you can simply restore your last configuration.

A cold start occurs when you turn on the power to the NWA3000-N
series AP. The NWA3000-N series AP powers up, checks the
hardware, and starts the system processes.
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 NWA3000-N series AP
writes all cached data to the local storage, stops the system
processes, and then does a warm start.
If you press the RESET button, the NWA3000-N series AP sets the
configuration to its default values and then reboots.
Clicking Maintenance > Shutdown > Shutdown or using the
shutdown command writes all cached data to the local storage and
stops the system processes. Wait for the device to shut down and
then manually turn off or remove the power. It does not turn off the
power.
Power off occurs when you turn off the power to the NWA3000-N
series AP. The NWA3000-N series AP simply turns off. It does not
stop the system processes or write cached data to local storage.
The NWA3000-N series AP does not stop or start the system processes when you
apply configuration files or run shell scripts although you may temporarily lose
access to network resources.
