Chapter 12 Command Line Interface Reference
aaa group server radius deadtime
aaa group server radius deadtime
To improve RADIUS response time when some servers might be unavailable, use the
aaa group server radius deadtime command to cause the storage router to skip the unavailable servers
in the specified group immediately. To set the dead time to 0, effectively preventing the storage router
from skipping any RADIUS server in the specified group, use the no form of this command.
aaa group server radius name deadtime minutes
no aaa group server radius name deadtime
Syntax Description
Defaults The dead time is set to zero (0) by default.
Command Modes Administrator.
Command History
Usage Guidelines Use this command to cause the storage router to mark as “dead” any RADIUS servers in the specified
group that fail to respond to authentication requests, thus avoiding the wait for the authentication request
to time out before trying the next configured server. A RADIUS server marked as dead is skipped by
additional requests for the specified number of minutes, unless all RADIUS servers in the specified list
are marked as dead. If all RADIUS servers in a group are marked as dead, the deadtime setting is ignored.
This command overrides the global setting that applies to all configured RADIUS servers. If the
deadtime is not set for a RADIUS server group, the global dead time setting applies.
In a cluster environment, AAA management functions are handled by a single storage router. To
determine which storage router is performing AAA management functions, issue the show cluster
command. If you issue the aaa group server radius deadtime command from a storage router that is
not performing AAA management functions, the CLI displays an informational message with the name
of the node that is currently handling those functions.
Examples The following example specifies a dead time of five minutes for all RADIUS servers in the group named
region2 that fail to respond to AAA authentication requests:
[SN5428-2A]# aaa group server radius region6 deadtime 5
name The name of the group of RADIUS servers. Enter a maximum of 31
characters.
minutes The length of time, in minutes, for which a RADIUS server in the specified
group is skipped over by the storage router when requesting AAA
authentication services, up to a maximum of 1440 minutes (24 hours).
