RADIUS Servers tab
The Radius Servers tab ( Figure 111 ) allows you to specify the RADIUS server that will be used for
authentication.
Figure 111 Security Center Radius Servers tab
You can specify up to three RADIUS servers per switch. The device that must be authenticated by the
RADIUS server always is display ed at the top of the table. If the first device does not respond after
a certain amount of time due to connection or configuration problems, the next device is
authenticated, and so on.
The RADIUS servers and Sequence table includes information about the following:
• The Host Name can be an IP Address.
• The UDP Port displays the number that the device uses to contact the RADIUS server. The port
number is
1812
by default.
• The Time out(sec) displays the amount of time to wait for a response from the RADIUS server
before retransmitting the packet. It can be
1
to
1000
; the default is
2
seconds.
• The Retries column specifies the number of times a packet is sent to a RADIUS server if a
response is not received before the timeout. After the retransmit limit is reached, the Gateway
switches to the next server. The value can be
1
to
100
; the default is
3
attempts.
• The Dead Time setting located below the RADIUS servers and Sequence table apply to all
available RADIUS servers. If a RADIUS server does not respond to an authentication request, it
can be marked as
dead
for a specified time interval. This can speed up authentication by
