Configuring the Switch for RADIUS Authentication
5-10
• 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 5-37.)
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 6, "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, none, or
authorized as a secondary, or backup, method. Note that for console access, if
you configure radius (or tacacs) for primary authentication, you must config-
