Introduction to the Cisco IOS and SDM

Here’s an example of how to configure both commands:

Todd(config-line)#line con 0

Todd(config-line)#exec-timeout ?

<0-35791> Timeout in minutes

Todd(config-line)#exec-timeout 0 ?

<0-2147483> Timeout in seconds

<cr>

Todd(config-line)#exec-timeout 0 0

Todd(config-line)#logging synchronous

You can set the console to go from never timing out (0 0) to timing out in

35,791 minutes and 2,147,483 seconds. The default is 10 minutes.

Telnet Password

To set the user-mode password for Telnet access into the router, use the line vty command.

Routers that aren’t running the Enterprise edition of the Cisco IOS default to five VTY lines,

0 through 4. But if you have the Enterprise edition, you’ll have significantly more. The best

way to find out how many lines you have is to use that question mark:

Todd(config-line)#line vty 0 ?

% Unrecognized command

Todd(config-line)#exit

Todd(config)#line vty 0 ?

<1-1180> Last Line number

<cr>

Todd(config)#line vty 0 1180

Todd(config-line)#password telnet

Todd(config-line)#login

Remember, you cannot get help from your (config-line)# prompt. You must go back to

privileged mode in order to use the question mark (?).

You may or may not have to set the login command before the password

on the VTY lines—it depends on the IOS version. The result is the same

either way.
