Table 60 Advanced Application > AAA > RADIUS Server Setup
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.
Delete Check this box if you want to remove an existing RADIUS 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.
