Chapter 1

Getting to Know Your ZyAIR

This chapter introduces the main features and applications of the ZyAIR.

1.1 Introducing the ZyAIR G-1000 Access Point

The ZyAIR G-1000 Access Point extends the range of your existing wired network without any additional
wiring efforts, providing easy network access to mobile users.

The ZyAIR incorporates the IEEE 802.11g standard for high-speed (up to 54 Mbps) wireless transmission. In
line with the standard, your ZyAIR is backward compatible with IEEE 802.11b-enabled devices.

Additionally, the ZyAIR offers highly secured wireless connectivity to your wired network with IEEE

802.1x, WEP data encryption and MAC address filtering.

The ZyAIR is easy to install and configure. The embedded web-based configurator and SNMP network
management enables remote configuration and management.

1.2 ZyAIR Features

Your ZyAIR has a number of features that give it the flexibility to provide a complete wireless networking
solution.

10/100M Auto-negotiating Ethernet/Fast Ethernet Interface

This auto-negotiating feature allows the ZyAIR to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either
half-duplex or full-duplex mode depending on your Ethernet network.

10/100M Auto-crossover Ethernet/Fast Ethernet Interface

The Etherent interface automatically adjusts to either a crossover or straight-through Ethernet cable.

Reset Button

The ZyAIR reset button is built into the top panel. Use this button to restore the factory default password to
1234; IP address to 192.168.1.2, subnet mask to 255.255.255.0.

Getting to Know Your ZyAIR 1-1

ZyAIR G-1000 Access Point User’s Guide

ZyAIR LED

The blue ZyAIR LED (also known as the Breathing LED) is on (dimmed) when the ZyAIR is on and blinks
brightly when data is being transmitted to/from its wireless stations. You may use the web configurator to
turn this LED off even when the ZyAIR is on and data is being transmitted/received.

802.11g Wireless LAN Standard

ZyAIR products containing the letter “G” in the model name, such as ZyAIR G-1000, ZyAIR G-2000,
support the 802.11g wireless standard.

802.11g will be fully compatible with the 802.11b standard. This means an 802.11b radio card can interface
directly with an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. 802.11g has
several intermediate rate steps between the maximum and minimum data rates. The 802.11g data rate and
modulation are as follows:

802.11g

Data Rate (Mbps) Data Rate (Mbps)

1 ~ 54 1 ~ 54

The ZyAIR may be prone to RF (Radio Frequency) interference from other 2.4 GHz

devices such as microwave ovens, wireless phones, Bluetooth enabled devices,

and other wireless LANs.

Wireless LAN MAC Address Filtering

Your ZyAIR checks the MAC address of the wireless station against a list of allowed or denied MAC
addresses.

IEEE 802.1x Network Security

The ZyAIR supports the IEEE 802.1x standard to enhance user authentication. Use the built-in user profile
database to authenticate up to 32 users using MD5 encryption. Use an EAP-compatible RADIUS (RFC2138,
2139 - Remote Authentication Dial In User Service) server to authenticate a limitless number of users using
EAP (Extensible Authentication Protocol). EAP is an authentication protocol that supports multiple types of
authentication.

Brute-Force Password Guessing Protection

The ZyAIR has a special protection mechanism to discourage brute-force password guessing attacks on the
ZyAIR’s management interfaces. You can specify a wait-time that must expire before entering a fourth
password after three incorrect passwords have been entered. Please see the appendix for details about this
feature.

1-2 Getting to Know Your ZyAIR

ZyAIR G-1000 Access Point User’s Guide

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your ZyAIR supports SNMP
agent functionality, which allows a manger station to manage and monitor the ZyAIR through the network.
The ZyAIR supports SNMP version one (SNMPv1) and version two c (SNMPv2c).

Full Network Management

The embedded web configurator is an all-platform web-based utility that allows you to easily access the
ZyAIR’s management settings. Most functions of the ZyAIR are also software configurable via the SMT
(System Management Terminal) interface. The SMT is a menu-driven interface that you can access from a
terminal emulator over a telnet connection.

Logging and Tracing

♦ Built-in message logging and packet tracing.

♦ Unix syslog facility support.

Embedded FTP and TFTP Servers

The ZyAIR’s embedded FTP and TFTP servers enable fast firmware upgrades as well as configuration file
backups and restoration.
