Page 269: Appendix B Wireless Lans
P P E N D I X 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).
Page 270: Figure 191 Basic Service Set
Appendix B Wireless LANs Figure 191 Basic Service Set 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.
Page 271: Figure 192 Infrastructure Wlan
Figure 192 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference.
Page 272: Figure 193 Rts/Cts
Appendix B Wireless LANs Figure 193 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
Page 273: Table 85 Ieee 802.11G
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type Preamble is used to signal that data is coming to the receiver.
Page 274: Table 86 Wireless Security Levels
Appendix B Wireless LANs Wireless security methods available on the ZyXEL Device are data encryption, wireless client authentication, restricting access by device MAC address and hiding the ZyXEL Device identity. The following figure shows the relative effectiveness of these wireless security methods available on your ZyXEL Device.
Page 275: Types Of Radius Messages
Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server.
Page 276 Appendix B Wireless LANs For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.
Page 277: Table 87 Comparison Of Eap Authentication Types
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 screen.
Page 278 Appendix B Wireless LANs Encryption Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
Page 279: Wireless Client Wpa Supplicants
Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration"...
Page 280: Figure 195 Wpa(2)-Psk Authentication
Appendix B Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them. Figure 195 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type.
Page 281: Antenna Characteristics
Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz (IEEE 802.11b) or 5GHz(IEEE 802.11a) is needed to communicate efficiently in a wireless LAN. Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
Page 282 Appendix B Wireless LANs For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down.

P P E N D I X Importing Certificates This appendix shows you how to import public key certificates into your web browser. Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar.

Page 313: Appendix E Ip Addresses And Subnetting
P P E N D I X IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
Page 314: Figure 252 Network Number And Host Id
Appendix E IP Addresses and Subnetting Figure 252 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation).
Page 315: Table 90 Subnet Masks
Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Table 90 Subnet Masks BINARY OCTET 8-bit mask 11111111 16-bit mask 11111111 24-bit mask 11111111...

In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.
Page 317: Figure 254 Subnetting Example: After Subnetting
Figure 254 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 2 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).

Page 321: Appendix F Text File Based Auto Configuration
P P E N D I X This chapter describes how administrators can use text configuration files to configure the wireless LAN settings for multiple APs. Text File Based Auto Configuration Overview You can use plain text configuration files to configure the wireless LAN settings on multiple APs.
Page 322: Table 100 Auto Configuration By Dhcp
Appendix F Text File Based Auto Configuration If adjacent APs use the same configuration file, you should leave out the channel setting since they could interfere with each other’s wireless traffic. Auto Configuration by DHCP A DHCP response can use options 66 and 67 to assign a TFTP server IP address and a filename.
Page 323: Figure 256 Configuration File Format
Use the following procedure to have the AP download the configuration file. Table 102 Configuration via SNMP STEPS MIB VARIABLE Step 1 pwTftpServer Step 2 pwTftpFileName Step 3 pwTftpFileType Step 4 pwTftpOpCommand Verifying Your Configuration File Upload Via SNMP You can use SNMP management software to display the configuration file version currently on the device by using the following MIB.
Page 324: Figure 257 Wep Configuration File Example
Appendix F Text File Based Auto Configuration Configuration File Rules You can only use the other ZyNOS commands but continues to check the next command. The AP ignores any improperly formatted commands and continues to check the next line. If there are any errors while processing the configuration file, the AP generates a message with the line number and reason for the first error (subsequent errors during the processing of an individual configuration file are not recorded).
