LABEL DESCRIPTION
Authentication
Server
Use this section to configure your RADIUS authentication settings.
Mode This field is only valid if you configure multiple RADIUS servers.
Select
index-priority and the Switch tries to authenticate with the first configured
RADIUS server, if the RADIUS server does not respond then the Switch tries to
authenticate with the second RADIUS server.
Select
round-robin to alternate between the RADIUS servers that it sends
authentication requests to.
Timeout Specify the amount of time in seconds that the Switch waits for an authentication
request response from the RADIUS server.
If you are using
index-priority for your authentication and you are using two
RADIUS servers then the timeout value is divided between the two RADIUS
servers. For example, if you set the timeout value to 30 seconds, then the Switch
waits for a response from the first RADIUS server for 15 seconds and then tries the
second RADIUS server.
Index This is a read-only number representing a RADIUS server entry.
IP Address Enter the IP address of an external RADIUS server in dotted decimal notation.
UDP Port The default port of a RADIUS server for authentication is 1812 . You need not
change this value unless your network administrator instructs you to do so.
Shared Secret Specify a password (up to 32 alphanumeric characters) as the key to be shared
between the external RADIUS server and the Switch. This key is not sent over the
network. This key must be the same on the external RADIUS server and the
Switch.
