Configuring System Information 173
•
Named Authentication Server Groups
— The number of authentication server groups configured on
the system. An authentication server group contains one or more configured authentication servers
that share the same RADIUS server name.
•
Named Accounting Server Groups
— The number of accounting server groups configured on the
system. An accounting server group contains one or more configured authentication servers that share
the same RADIUS server name.
•
Max Number of Retransmits
— The value of the maximum number of times a request packet is
retransmitted. The valid range is 1-10. Consideration to maximum delay time should be given when
configuring RADIUS max retransmit and RADIUS timeout. If multiple RADIUS servers are
configured, the max retransmit value on each will be exhausted before the next server is attempted. A
retransmit will not occur until the configured timeout value on that server has passed without a
response from the RADIUS server. Therefore, the maximum delay in receiving a response from the
RADIUS application equals the sum of (retransmit times timeout) for all configured servers. If the
RADIUS request was generated by a user login attempt, all user interfaces will be blocked until the
RADIUS application returns a response.
•
Timeout Duration
— The timeout value, in seconds, for request retransmissions. The valid range is 1 -
30. See the Max Number of Retransmits field description for more information about configuring the
timeout duration.
•
Accounting Mode
— Use the menu to select whether the RADIUS accounting mode is enabled or
disabled on the current server.
•
RADIUS Attribute 4 (NAS-IP Address)
— To set the network access server (NAS) IP address for the
RADIUS server, select the option and enter the IP address of the NAS in the available field. The
address should be unique to the NAS within the scope of the RADIUS server. The NAS IP address is
only used in Access-Request packets.
RADIUS Server Configuration
From the RADIUS Server Configuration page, you can add a new RADIUS server, configure settings for
a new or existing RADIUS server, and view RADIUS server status information. The RADIUS client on
the switch supports up to 32 named authentication and accounting servers.
To access the RADIUS Server Configuration page, click System > Management Security > RADIUS
Server Configuration in the tree view.
