Operation of Device Authentication

Device authentication forces the radio to authenticate before allowing 
user traffic to traverse the wireless network. When Device Security is 
configured to use RADIUS as the Authentication Method, Remote 
radios need three types of certificates: public (client), private, and root 
(Certificate Authority). These files are unique to each Remote radio and 
need to first be created at the server and then installed into each unit via 
TFTP. The certificate files must be in DER format.

Device authentication uses the serial number of each radio as the 
Common Name (CN) in its certificate and in its RADIUS identity field. 
Each Access Point 

and

 Remote radio must be identified/recognized by 

the RADIUS Server through the Common Name (Serial number) and IP 
address entries.

NOTE:

Consult your RADIUS network administrator for assistance in
configuration, or for help with other issues that may arise.

To activate device authentication, select 

Device Auth Method

 and set 

RADIUS

 as the active mode. The behavior of this setting differs 

depending on whether it is implemented on an Access Point or a Remote 
transceiver. An explanation of these behaviors is given below:

Access Point:

 When 

Device Auth Method

 is set to 

RADIUS

, the AP disasso-

ciates all associated Remotes and waits for the RADIUS Server to 
Authenticate the Remotes before allowing data to be passed from them. 
When approval is received from the RADIUS Server, data from the 
Remote is allowed to pass.

Remote:

 When 

Device Auth Method

 is set to 

RADIUS

, the Remote halts any 

data it is passing, and requests Authentication from the RADIUS Server. 
If accepted, data is allowed to be transmitted.

Operation of User Authentication

When user authentication is set to 

Local

 or 

RADIUS

, you must enter a 

valid user name and password before being allowed to manage the radio. 
In 

RADIUS

 mode both of these fields may be up to 40 characters long. In 

Local

 mode the user name is 

iNET

 and the password may be up to 8 char-

acters long.

When set to 

RADIUS

all

 logins to the local configuration services are 

required to be authenticated via the RADIUS Server, including telnet 
and SSH (Secure Shell) sessions. Authentication must be accepted 
before access to the radio menu is granted.
