Chapter 12 Command Line Interface Reference

radius-server deadtime

To improve RADIUS response time when some servers might be unavailable, use the

radius-server deadtime command to cause the storage router to skip the unavailable servers

immediately. To set the dead time to 0, effectively preventing the storage router from skipping any

RADIUS server, use the no form of this command.

radius-server deadtime minutes

no radius-server 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 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 are marked as dead. If all RADIUS servers are

marked as dead, the deadtime setting is ignored.

This is a global command that applies to all configured RADIUS servers. To override the global dead

time setting for a specific group of RADIUS server, use the aaa group server radius deadtime

command.

Examples The following example specifies a dead time of five minutes for all RADIUS servers that fail to respond

to AAA authentication requests:

[SN5428-2A]# radius-server deadtime 5

The following example effectively sets a dead time of zero minutes for all RADIUS servers. The storage

router will wait for any AAA authentication request to a RADIUS server to time out before

retransmitting or retrying the next configured server.

[SN5428-2A]# no radius-server deadtime

minutes The length of time, in minutes, for which a RADIUS server is skipped over

by the storage router when requesting AAA authentication services, up to a

maximum of 1440 minutes (24 hours).
