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.
Delete Check this box if you want to remove an existing server entry
from the Switch. This entry is deleted when you click Apply.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
Accounting

Timeout Specify the amount of time in seconds that the Switch waits for an
accounting request response from the server.
Index This is a read-only number representing a accounting server
entry.
IP Address Enter the IP address of an external accounting server in dotted
decimal notation.
TCP Port The default port of a accounting server is 49. You need not
change this value unless your network administrator instructs you to do
so.
