LABEL DESCRIPTION
Authentication
Server
Use this section to configure your authentication settings.
Mode This field is only valid if you configure multiple servers.
Select
index-priority and the Switch tries to authenticate with the first configured
server, if the server does not respond then the Switch tries to
authenticate with the second server.
Select
round-robin to alternate between the 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 server.
If you are using
index-priority for your authentication and you are using two
servers then the timeout value is divided between the two
servers. For example, if you set the timeout value to 30 seconds, then the Switch
waits for a response from the first server for 15 seconds and then tries
the second server.
Index This is a read-only number representing a server entry.
IP Address Enter the IP address of an external server in dotted decimal notation.
TCP Port The default port of a server for authentication is 49 . You need not
change this value unless your network administrator instructs you to do so.
