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.
Chapter 1 Introduction 1.2 Applications for the NWA3000-N series AP The NWA3000-N series AP can be configured to use the following operating 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.
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.
Chapter 1 Introduction 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 NWA3000-N series AP.
Chapter 1 Introduction • 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.
Chapter 1 Introduction 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 security between the wireless stations and the AP. If you do not enable WDS security, traffic between APs is not encrypted.
Chapter 1 Introduction 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 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.
Chapter 1 Introduction The following figure illustrates a CAPWAP wireless network. The user (U) configures the controller AP (C), which then automatically updates the configurations of the managed APs (M1 ~ M4). Figure 7 CAPWAP Network Example U C M1 M2 M3 M4 1.4 Ways to Manage the NWA3000-N series AP You can use the following ways to manage the NWA3000-N series AP. Web Configurator The Web Configurator allows easy NWA3000-N series AP setup and management using an Internet browser.
Chapter 1 Introduction Console Port You can use the console port to manage the NWA3000-N series AP using CLI commands. See the Command Reference Guide for more information about the CLI. The default settings for the console port are as follows. Table 1 Console Port Default Settings SETTING VALUE Speed 115200 bps Data Bits 8 Parity None Stop Bit 1 Flow Control Off File Transfer Protocol (FTP) This protocol can be used for firmware upgrades and configuration backup and restore.
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 your password, you will have to reset the NWA3000-N series AP to its factory default settings. If you backed up an earlier configuration file, you won’t have to totally re-configure the NWA3000-N series AP; you can simply restore your last configuration. 1.

CHAPTER 7 Management Mode 7.1 Overview This chapter discusses using the NWA3000-N series AP in management mode, which determines whether the NWA3000-N series AP is used in its default standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP) network. 7.2 About CAPWAP The NWA3000-N series AP supports CAPWAP. This is ZyXEL’s implementation of the CAPWAP protocol (RFC 5415). The CAPWAP dataflow is protected by Datagram Transport Layer Security (DTLS).
Chapter 7 Management Mode Note: The NWA3000-N series AP can be a standalone AP (default), a CAPWAP managed AP, or a CAPWAP AP controller. 7.2.1 CAPWAP Discovery and Management The link between CAPWAP-enabled access points proceeds as follows: 1 An AP in managed AP mode joins a wired network (receives a dynamic IP address). 2 The AP sends out a discovery request, looking for an AP in CAPWAP AP controller mode. 3 If there is an AP controller on the network, it receives the discovery request.
Chapter 7 Management Mode • Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network. DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to reach the AP controller in a different subnet, as shown in the following figure. Figure 39 CAPWAP and DHCP Option 138 SUBNET 1 SUBNET 2 DHCP SERVER + OPTION 138 CAPWAP TRAFFIC AP CONTROLLER (STATIC IP) MANAGED AP 7.2.
Chapter 7 Management Mode Note: After you change the operation mode, the NWA3000-N series AP resets to its default settings for the mode you set it to, including the IP address of 192.168.1.2. It also backs up its configuration to a xxx-backup.conf file where xxx denotes the mode the NWA3000-N series AP was previously using. Click Configuration > MGNT MODE in the NWA3000-N series AP’s navigation menu. The following screen displays.

Chapter 9 Wireless Table 42 Configuration > Wireless > Load Balancing (continued) LABEL Disassociate station when overloaded DESCRIPTION Select this option to “kick” wireless clients connected to the AP when it becomes overloaded. If you do not enable this option, then the AP simply delays the connection until it can afford the bandwidth it requires, or it shunts the connection to another AP within its broadcast radius.
Chapter 9 Wireless delays the red laptop’s connection until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare. Figure 50 Delaying a Connection The second response your AP can take is to kick the connections that are pushing it over its balanced bandwidth allotment. Figure 51 Kicking a Connection Connections are kicked based on either idle timeout or signal strength.
Chapter 9 Wireless 9.6 DCS Use this screen to configure dynamic radio channel selection. Click Configuration > Wireless > DCS to access this screen. Figure 52 Configuration > Wireless > DCS Each field is described in the following table.
Chapter 9 Wireless Table 43 Configuration > Wireless > DCS (continued) LABEL DESCRIPTION DCS Sensitivity Level Select the AP’s sensitivity level toward other channels. Options are High, Medium, and Low. Generally, as long as the area in which your AP is located has minimal interference from other devices you can set the DCS Sensitivity Level to Low. This means that the AP has a very broad tolerance.
Chapter 9 Wireless Table 43 Configuration > Wireless > DCS (continued) LABEL DESCRIPTION Enable 5-GHz DFS Aware Select this if your APs are operating in an area known to have RADAR devices. This allows the device to downgrade its frequency to below 5 GHz in the event a RADAR signal is detected, thus preventing it from interfering with that signal. Enabling this forces the AP to select a non-DFS channel.
Chapter 9 Wireless Figure 53 An Example Three-Channel Deployment Three channels are situated in such a way as to create almost no interference with one another if used exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not interfere with neighboring APs as long as they are also limited to same trio.
Chapter 9 Wireless Load Balancing Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in areas crowded with wireless users. Rather than let every user connect and subsequently dilute the available bandwidth to the point where each connecting device receives a meager trickle, the load balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
CHAPTER 10 Device HA 10.1 Overview Device HA is available when the NWA3000-N series AP is in controller mode.

CHAPTER 14 Certificates 14.1 Overview The NWA3000-N series AP can use certificates (also called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key. Certificates provide a way to exchange public keys for use in authentication. 14.1.1 What You Can Do in this Chapter • The My Certificate screens (Section 14.
Chapter 14 Certificates This process works as follows: 1 Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). 2 Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not.

APPENDIX C Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Appendix C Wireless LANs with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 128 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.
Appendix C Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 129 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area.
Appendix C Wireless LANs hidden node. Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 130 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel.
Appendix C Wireless LANs Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
Appendix C Wireless LANs several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows: Table 114 IEEE 802.11g DATA RATE (MBPS) MODULATION 1 DBPSK (Differential Binary Phase Shift Keyed) 2 DQPSK (Differential Quadrature Phase Shift Keying) 5.
Appendix C Wireless LANs IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are: • User based identification that allows for roaming.
Appendix C Wireless LANs • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting: • Accounting-Request Sent by the access point requesting accounting.
Appendix C Wireless LANs However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key.
Appendix C Wireless LANs Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen.
Appendix C Wireless LANs If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not. Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2. Encryption WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x.
Appendix C Wireless LANs keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) User Authentication WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network.
Appendix C Wireless LANs 4 The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. Figure 131 WPA(2) with RADIUS Application Example WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows.
Appendix C Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 132 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type.

Appendix D Open Software Announcements The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
Appendix D Open Software Announcements we use the Lesser General Public License. In other cases, permission to use a particular library in nonfree programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system.
Appendix D Open Software Announcements Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole.
Appendix D Open Software Announcements License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License.

Appendix D Open Software Announcements Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow.
