Installing the W-68
When the W-68 functions as a WIPS sensor, it monitors your network and communicates with the server to guard
your corporate network against over-the-air attacks.
Clients can connect to your corporate network in wireless mode through the W-68 AP(s).
The W-68 must be plugged into your corporate network to perform the above-mentioned operation.
As a WIPS sensor, W-68 can be configured in one of the following two modes:

Sensor Mode: This is the default mode. In this mode, the device can be connected to a trunk port
(802.1Q capable) on a switch. The device then monitors the VLANs that are configured on that trunk port
and are chosen by the user. In this mode, the W-68 can monitor up to 16 VLANs. The wireless interface
of the sensor is enabled for WIPS operations.

Network Detector (ND) Mode: This mode needs to be explicitly configured. In this mode, the device can
be connected to a trunk port (802.1Q capable) on a switch. The device then monitors the VLANS that are
configured on that trunk port and are chosen by the user. In this mode, the W-68 can monitor up to 100
VLANs. The wireless interface of the ND is disabled.
Important: To prevent disconnection or tampering by unauthorized personnel, it is extremely important to install
the device such that it is difficult to unplug the device from the network or from the power outlet.
Zero-Configuration of W-68 as Sensor
Zero-configuration is supported under the following conditions:

The device is in sensor mode.

A DNS entry wifi-security-server is set up on all the DNS servers. This entry should point to the IP
address of the server. By default, the device looks for the DNS entry wifi-security-server.

The device is placed on a subnet that is DHCP enabled.
Important: If the device is placed on a network segment that is separated from the server by a firewall, you must
first open port 3851 for User Datagram Protocol (UDP) and Transport Control Protocol (TCP) bidirectional traffic
on that firewall. This port number is assigned to AirTight® Networks. If multiple devices are set up to connect to
multiple servers, zero-configuration is not possible. In this case, you must manually configure the sensors. Refer
to Manually Configuring W-68 for further details.
The steps to install the device with no configuration (zero-configuration) are as follows.
1. Mount the device
2. Power on the device.
3. Connect the device to the network.
Connecting W-68
This involves mounting the W-68, powering on the device, and connecting it to the wired network.
Mount W-68
Take a configured W-68, that is, ensure that a static IP is assigned to the device or the settings have been
changed for DHCP. Note the MAC address and the IP address of the device in a safe place before it is installed in
its appropriate location. The MAC address of the device is printed on a label at the rear side of the product.
Recommended: You should label the devices using MAC addresses or at least your own convention. For
example, use serial numbers, so that you can easily identify the devices.

Power on W-68
A W-68 device can be powered on by 802.3af Class 0 Power Over Ethernet (PoE) of Nominal input voltage 48V
DC. You can connect the device to the network using PoE or a power adapter.
Connect W-68 to the Network
To connect W-68 to the network, perform the following steps.
1. Ensure that a DHCP server is already available on the network to enable network configuration of the W68.
2. Add the DNS entry wifi-security-server on all DNS servers. This entry should point to the IP address of
the server.
3. Ensure that DHCP is running on the subnet to which the device will be connected.
Important: If DHCP is not enabled on a subnet, the device cannot connect to that subnet with zero-configuration.
If the DNS entry is not present on the DNS servers or you do not have the DHCP server running on the subnet,
you must manually configure the device. Refer to Manually Configuring W-68 for further details.
Using W-68 with PoE
To power on and connect W-68 to the network using PoE, do the following:
1. Connect one end of the network interface cable to the Ethernet port at the rear of the W-68.
2. Connect the other end of the network interface cable to the Ethernet jack that provides PoE power.

Manually Configuring W-68
Important: If the installation in the previous chapter was successful, stop! You do not need to configure the
device manually.
Introduction
Manual configuration of W-68 is typically required in the following cases:

Devices cannot connect to the server through zero-configuration.

Device needs to be configured in the ND mode.

Sensor Only (SO) devices cannot connect to the server through zero-configuration. The DNS entry for the
server has been changed to an entry other than wifi-security-server or a DNS server is not present in
the network. This is applicable for multi-server installations.

Device is placed on a subnet that is not DHCP enabled.
Configuring AP through Config Shell
The Config Shell supports a pre-defined set of commands used to configure the W-68 device. Log in to the device
console using the SSH shell.
The steps to configure the device manually through the SSH shell are as follows:
1. Log in and change the default password
2. Set Server Discovery
3. Set Sensor Mode
4. Configure Network Settings
Log in and Change the Default Password
Log in to the Config Shell using the user name config and password config. Change the default password using
the passwd command. You can change the device password using device templates. Refer to Manage Device
Template section under the AirTight Management Console Configuration chapter, in the AirTight Management
Console User’s Guide for more details.
Recommended: Although not mandatory, as a best practice we recommend that you change the default password.
W-68 Installation Guide

Set Server Discovery
The next step is to set the server discovery information. The following are the types of server discovery:

Server IP based discovery (preferred)

Service Location Protocol (SLP) based discovery (if wifi-security-server service has been configured)
Use the set server discovery command to point the AP device to the correct server.
Figure 4-1 The set server discovery Command
Note: If IP address/ host name based discovery is being used and more than one server is present on the network,
then you must enter the IP address of the appropriate server.
Set Sensor Mode
The next step is to set the mode of the sensor. There are two possible modes:

Sensor Mode: This is the default mode. In this mode, the device can be connected to a trunk port
(802.1Q capable) on a switch. The device then monitors multiple VLANs that are configured on that trunk
port and are chosen by the user. The wireless interface of the sensor is enabled. In this mode, a W-68
can monitor up to 16 VLANs.

ND Mode: This mode needs to be explicitly configured. In this mode, the device can be connected to a
trunk port (802.1Q capable) on a switch. It then monitors multiple VLANs that are configured on that trunk
port and are chosen by the user. The wireless interface of the ND is disabled. In this mode, a W-68
functioning as a WIPS sensor can detect and monitor up to 100 VLANs.
Use the set mode command to set the device mode for W-68.
Figure 4-2 The set mode Command for W-68
W-68 Installation Guide
17
Configure Network Settings
After the mode is set, you have to configure the network settings. For the Network Detector/Sensor mode, use the
set vlan config command to configure the IP addresses on the ND.
With the set vlan config command, you can do the following.

Add /modify VLAN settings to be configured with DHCP.

Add/modify VLAN settings to be configured with a static IP address.

Set communication VLAN.
To configure VLANs, do the following.
1. Type the set vlan config command to configure all the VLANs.
2. Choose option 1 to configure VLANs for DHCP and option 2 to configure VLANs with static IP address.
The device will restart / reboot after the VLAN configuration.
To configure VLANs with DHCP, you must provide comma-separated VLAN IDs.
W-68 Installation Guide
18
To configure VLANs with static IP address, you must provide the IP address, the subnet mask and the gateway.
To configure/ change the Communication VLAN, do the following
1. Type the set vlan config command.
2. Choose option 3 from the menu that appears.
Configure a static IP address in absence of a DHCP server
1. Connect a crossover cable from the computer to the Ethernet port of W-68.
2. Configure the LAN IP address on the computer in the subnet 192.168.1.0/24.
3. SSH to IP address: 192.168.1.245 (factory default)
4. Log in to the CLI of the device using default credentials.
5. Configure server discovery on the device.
6. Configure a static IP address on the device. For example: Untagged VLAN 192.168.2.x/24.
After completing this step you will lose the SSH connection.
7. Configure the LAN IP address in the range of 192.168.2.x/24 and again SSH to the address assigned
in step 6.
8. Check the configuration settings.
9. Remove the crossover connection to the computer and connect the Ethernet port to the local switch.
Configure IPv6 settings
W-68 is IPv6 capable. Use the set ipv6 config command to configure advanced options such as DHCP
settings, auto negotiation, and manual configuration.

Enable auto negotiation to discover IP address automatically.

Enable DHCP settings to obtain addressing as well as more information, such as the DNS address from
DHCP server in the network.

Enable manual configuration to provide manual IPv6 address as well as IPv6 default gateway.
How to configure Communication Key or Passphrase

Drawing AF Power from W-68
LAN 4 can behave as a PoE by itself. If AT power is provided through WAN, it is possible to draw AF power from
the LAN4. In this situation, the LAN4 behaves as a PoE and can power another device or AP that can run on AF
power.
While the existing 802.3af standard has made it possible to power VoIP phones, wireless APs, even some
cameras over standard Ethernet cabling since 2003, it cannot meet the demands of some higher-end devices,
including cameras with pan/tilt/zoom capabilities, door controllers and POS terminals. In addition, APs that
support the upcoming 802.11n standard will likely require the power of 802.3at, although single-radio 802.11n APs
should be able to work with 802.3af. As other devices that previously needed individual power supplies become
more energy efficient, they might become candidates for 802.3at as their lower requirements bring them into
range of that spec.

W-68 Troubleshooting
Following are the troubleshooting guidelines for W-68.
Symptoms
Wi-Fi: any
Ethernet: fast blink
Power: solid Green
Diagnosis
Solution
The device did not
receive a valid IP
address via the
DHCP.
Ensure that the DHCP server is on and available on the
VLAN/subnet to which the device is connected. If the device
still fails to get a valid IP address, you can reboot it to see if
the problem is resolved.
The Ethernet cable is
loose. The device is
probably
disconnected from
the network.
Ensure that the Ethernet cable is connected.
Ensure that the server is running and is reachable from the
network to which the device is attached. If there is a firewall
or a router with ACLs enabled between the device and the
server, ensure that the traffic is allowed on UDP port 3851.
Wi-Fi: any
Ethernet: slow blink
Power: solid Green
Unable to connect to
the server
Use the server IP-based discovery and ensure that you have
correctly entered the DNS name, wifi-security-server, on
the DNS server. Also, ensure that the DNS server IP
addresses are either correctly configured on the, or are
provided by the DHCP server.
It is also possible that the AP is unable to connect to the
server because it has failed to authenticate with the server. In
this case, an 'Authentication failed for ' event is raised on the
server. Refer to the event for recommended action.

Appendix A: Sensor-Server Mutual Authentication
The Sensor-server communication begins with a mutual authentication step in which the sensor and server
authenticate each other using a shared secret. The sensor-server communication takes place only if this
authentication succeeds.
After the authentication succeeds, a session key is generated. All communication between the sensor and server
from this point on is encrypted using the session key.
The sensor and server are shipped with the same default value of the shared secret. The CLI commands are
provided on both server and sensor for changing the shared secret.
Note: After the shared secret (communication key) is changed on the server, all sensors connected to the server
will automatically be set up to use the new communication key. Sensors that are not connected to the server at
this time must be manually set up with the same communication key to enable communication with this server.
Note: Although the server is backward compatible, that is, older version sensors can connect to a newer version
server, this is not recommended.
