for that router, it already has the default password. If i create the user name inside, will it use back the defalt password?

are you talking about the enable password or the console password?

The enable password will remain the same, but if you enable local authentication at the console level, then that's what will be used. If you had a different console password it will be ignored for local authentication. Same goes for vty lines

cisco2600#config t

cisco2600#enable username User1

Is it like that?

default password for what? When you telnet or when you console in?

cisco2600#config t

cisco2600username User1 password testpassword

The above commands only create the users.

you have to apply them to a console or vty line.

when i console in, i need to type >en. Then, it will prompt me for password. This is what i mean for default passsword.

Hi,

The explaination is quiet clear. Thanks. May i know whether more than 1 username can be created per router?

Yes, you can add more than one username per router. Just repeat the command, but put in a different username -- it will then keep both.

Remember, to make this active, you need to add:

line con 0 ;for use when consoling in

login local

line vty 0 4 ;for use when telnetting in

login local

Also, another option is to use an extended form of the command:

username TEST privilege 15 password TEST

By adding that 'privilege 15' bit in the middle, when you login using that username you will automatically go into enable mode, without having to also type in 'en' and the other password.
