• Timeout Period: The timeout period the switch waits for a RADIUS
server to reply. (Default: 5 seconds; range: 1 to 15 seconds.)
• Retransmit Attempts: The number of retries when there is no server
response to a RADIUS authentication request. (Default: 3; range of 1
to 5.)
• Server Dead-Time: The period during which the switch will not send
new authentication requests to a RADIUS server that has failed to
respond to a previous request. This avoids a wait for a request to time
out on a server that is unavailable. If you want to use this feature,
select a dead-time period of 1 to 1440 minutes. (Default: 0—disabled;
range: 1 - 1440 minutes.) If your first-choice server was initially
unavailable, but then becomes available before the dead-time expires,
you can nullify the dead-time by resetting it to zero and then trying to
log on again. As an alternative, you can reboot the switch, (thus
resetting the dead-time counter to assume the server is available) and
then try to log on again.
Number of Login Attempts: This is actually an aaa authentication
•
command. It controls how many times per session a RADIUS client
(and clients using other forms of access) can try to log in with the
correct username and password. (Default: Three times per session.)
(For RADIUS accounting features, refer to "Configuring RADIUS Accounting"
on page 6-21.)

1. Configure Authentication for the Access Methods

You Want RADIUS To Protect

This section describes how to configure the switch for RADIUS authentication
through the following access methods:
■ Console: Either direct serial-port connection or modem connection.
Telnet: Inbound Telnet must be enabled (the default).
■
SSH: To use RADIUS for SSH access, first configure the switch for
■
SSH operation. Refer to chapter 7, "Configuring Secure Shell (SSH)" .
Web: You can enable RADIUS authentication for web browser inter-
■
face access to the switch.
You can configure RADIUS as the primary password authentication method
for the above access methods. You also need to select either local or none as
a secondary, or backup, method. Note that for console access, if you configure
