Installing the C-75
When the C-75 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 C-75 AP(s).
The C-75 must be plugged into your corporate network to perform the above-mentioned operation.
From release 7.1 Update 4, the C-75 can also detect cellular activity. You must plug in the cellular activity
detection device into the USB port of the C-75 to detect cellular activity.
Note: In case the C-75 device is already deployed and functional, you need to reboot the device after plugging
in the cellular activity detection device.
As a WIPS sensor, C-75 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, an C-75 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, an C-75 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 C-75 as Access Point
Zero-configuration is supported under the following conditions:
The device is in AP mode with background scanning on with no SSID configured.
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 Mojo 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
The steps to install the device with no configuration (zero-configuration) are as follows.
Manually Configuring C-75
1. Mount the device
2. Power on the device.

Power on C-75
A C-75 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 C-75 to the Network
To connect C-75 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 C-75.
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 zeroconfiguration. 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

Introduction
Manual configuration of C-75 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 C-75 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

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 C75 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
C-75 functioning as a WIPS sensor can detect and monitor up to 100 VLANs.
Use the set mode command to set the device mode for C-75.

Symptoms
Diagnosis
Solution
Wi-Fi: any
Ethernet: fast blink
Power: solid orange
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.
Wi-Fi: any
Ethernet: slow blink
Power: solid orange
Unable to connect to
the server
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.
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
Note
: Although the server is backward compatible, that is, older version sensors can connect to a newer
version server, this is not recommended.
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.
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.
