Introduction to the Cisco IOS and SDM

Here’s an example of setting the enable passwords:

Todd(config)#enable secret todd

Todd(config)#enable password todd

The enable password you have chosen is the same as your

enable secret. This is not recommended. Re-enter the

enable password.

If you try to set the enable secret and enable passwords the same, the router will give you

a nice, polite warning to change the second password. If you don’t have older legacy routers,

don’t even bother to use the enable password.

User-mode passwords are assigned by using the line command:

Todd(config)#line ?

<0-337> First Line number

aux Auxiliary line

console Primary terminal line

tty Terminal controller

vty Virtual terminal

x/y Slot/Port for Modems

x/y/z Slot/Subslot/Port for Modems

Here are the lines to be concerned with:

aux Sets the user-mode password for the auxiliary port. It’s usually used for attaching a

modem to the router, but it can be used as a console as well.

console Sets a console user-mode password.

vty Sets a Telnet password on the router. If this password isn’t set, then Telnet can’t be used

by default.

To configure the user-mode passwords, you configure the line you want and use either the

will provide a line-by-line example of the configuration of each line.

Auxiliary Password

To configure the auxiliary password, go into global configuration mode and type line aux ?.

You can see here that you only get a choice of 0–0 (that’s because there’s only one port):

Todd#config t

Enter configuration commands, one per line. End with CNTL/Z.

Todd(config)#line aux ?

<0-0> First Line number

Todd(config)#line aux 0

Todd(config-line)#login
