Command Syntax

The following commands control the timeout for the login sequence prompts (username, password). If you dial in via async and run a script that shows the username and password provided by the Cisco router, you may need to extend the 30-second default.

tacacs-server login-timeout [seconds]   

!--- Original version.

timeout login response [seconds]        

!--- Updated version.

The commands are functionally identical. The command syntax was first changed in Cisco IOS Releases 11.3(4), 11.3(4)T, 11.3(4)WA4, and 12.0(1).

Original command syntax:

isdn2-2(config)#tacacs-server login-timeout ?
 <1-300>  Max seconds to wait

 isdn2-2(config)#tacacs-server login-timeout 300

Current command syntax:

isdn2-2(config-line)#timeout login response ?
  <0-300>  Timeout in seconds

isdn2-2(config-line)#timeout login response 300

Note: The original command was global. The current (updated) command is a line configuration command.


The default time between username prompts is 30 seconds. If you set the time to 60 seconds, the client will be prompted every 60 seconds, for a maximum of three times, if no user input is detected. The commands are not Terminal Access Controller Access Control System (TACACS) dependent—you do not need to run TACACS or any authentication, authorization, and accounting (AAA).

The original command was renamed through CSCdj20257.
