These are used to configure a password when user mode is accessed either through the console port, through the auxiliary port, or via Telnet.

Telnet - VTY 0 4

(Config)#line vty 0 4
(Config)#password cisco
(Config)#login

Consol - Con 0

(Config)#line con 0
(Config)#password cisco
(Config)#login

Auxiliary - aux 0

(Config)#line aux 0
(Config)#password cisco
(Config)#login

Alam, the router does not care what your client tries to telnet to, be it an ip address or name. What you are trying to do is set up name resolution on your client. There are two ways to do this.

The easiest way, if you use the same client machine to telnet into your router all the time, is to edit the hosts file on your client computer to associate the name of your router with the ip address of that same router. Once you do this, connecting to “Router-name” and the associated ip address will have the same effect.

The other way, if you and a bunch of other people need access to this router, is to add an entry in your DNS server for the name of the router and any (or all) ip addresses that it should be reachable from. If you do not manage your own DNS server, you will have to ask the administrator to do this for you.

Remember, you can have more than one ip address associated with a router, for instance an external and an internal. Make sure you specify all ip addresses you want to be reachable as separate host file entries or DNS aliases.

For noobiew

If the router will scream at you

Router(config-line)#login ?
authentication Authentication parameters.
ctrlc-disable Disable CONTROL-C during login.

you probably have AAA enabled (you have aaa new-model in your config)

You need to create a method list, I’ll recomend stick with the default;

aaa authentication login default local

On vty / console
login authentication default

Hope that was helpful.

Hi, I know that you might have configured the password prior to do this. If not, Can you please try to configure “login” command after you set the password globally ?

Thanks,
