Configuring RADIUS Authentication and Accounting
3. Configure the Switch’s Global RADIUS Parameters
You can configure the switch for the following global RADIUS parameters:
■ Number of login attempts: In a given session, specifies how many tries at entering the
correct username and password pair are allowed before access is denied and the session
terminated. (This is a general aaa authentication parameter and is not specific to RADIUS.)
■ Global server key: The server key the switch will use for contacts with all RADIUS servers
for which there is not a server-specific key configured by radius-server host < ip-address > key
< key-string >. This key is optional if you configure a server-specific key for each RADIUS
server entered in the switch. (Refer to “2. Configure the Switch To Access a RADIUS Server”
on page 109.)
■ Server timeout: Defines the time period in seconds for authentication attempts. If the
timeout period expires before a response is received, the attempt fails.
■ Server dead time: Specifies the time in minutes during which the switch avoids requesting
authentication from a server that has not responded to previous requests.
■ Retransmit attempts: If the first attempt to contact a RADIUS server fails, specifies how
many retries you want the switch to attempt on that server.
Syntax: aaa authentication num-attempts <1 .. 10 > Specifies how many tries for entering the
correct username and password before
shutting down the session due to input errors.
(Default: 3; Range: 1 - 10)
[no] radius-server
key < global-key-string > Specifies the global encryption key the switch
uses for sessions with servers for which the
switch does not have a server-specific key
assignment. This key is optional if all RADIUS
server addresses configured in the switch
include a server-specific encryption key.
(Default: Null.)
dead-time < 1 .. 1440 > Optional. Specifies the time in minutes during
which the switch will not attempt to use a
RADIUS server that has not responded to
an earlier authentication attempt. (Default: 0;
Range: 1 - 1440 minutes)
radius-server timeout < 1 .. 15 > Specifies the maximum time the switch waits
for a response to an authentication request
before counting the attempt as a failure.
(Default: 3 seconds; Range: 1 - 15 seconds)
