RADIUS authentication features  
The switch supports the following RADIUS authentication features: 
 
Supports RADIUS client on the switch, based on the protocol definitions in RFC 2138 and 
RFC 2866. 
 
Allows RADIUS secret password up to 32 bytes. 
 
Supports secondary authentication server so that when the primary authentication server is 
unreachable, the switch can send client authentication requests to the secondary authentication 
server. Use the 
/cfg/sys/radius/cur
 command to show the currently active RADIUS 
authentication server. 
 
Supports user-configurable RADIUS server retry and time-out values: 
 
Time-out value = 1-10 seconds 
 
Retries = 1-3 
 
The switch will time out if it does not receive a response from the RADIUS server in one to three 
retries. The switch will also automatically retry connecting to the RADIUS server before it declares the 
server down. 
 
Supports user-configurable RADIUS application port. The default is 1645/User Datagram Protocol 
(UDP)-based on RFC 2138. Port 1812 is also supported. 
 
Allows network administrator to define privileges for one or more specific users to access the switch 
at the RADIUS user database. 
 
Allows the administrator to configure RADIUS backdoor and secure backdoor for Telnet, SSH, HTTP, 
and HTTPS access. 
User accounts for RADIUS users 
The user accounts listed in the following table can be defined in the RADIUS server dictionary file.

 User access levels 
 
User account 
Description and tasks performed 
User 
User interaction with the switch is completely passive; nothing can be changed on the 
switch. Users may display information that has no security or privacy implications, such as 
switch statistics and current operational state information. 
Operator 
Operators can only effect temporary changes on the switch. These changes are lost when 
the switch is rebooted/reset. Operators have access to the switch management features 
used for daily switch operations. Because any changes an operator makes are undone by a 
reset of the switch, operators cannot severely impact switch operation, but do have access 
to the Maintenance menu. By default, the operator account is disabled and has no 
password.
