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.
Shared Secret Specify a password (up to 32 alphanumeric characters) as the key to be shared between the
external server and the Switch. This key is not sent over the network. This key
must be the same on the external server and the Switch.
Note that as you type a password, the screen displays an asterisk (*) for each character you
type.
