Cisco 1720 password issue?

Any ideas on why I would be receiving the following error when I attempt to remotely login (telnet) into a 1720 Access router; Password required, but none set - it then immediately brings me back to a command prompt.

I found a Cisco article that discusses this topic and it recommended doing a password recovery - which I have done but am still getting the same error.

Any insight anyone could provide is appreciated!

Re: Cisco 1720 password issue?

There are two related commands in the configuration. They are "password" and "login". The command "login" tells the router that it is required to ask for a password when access is attempted. The command "password" tells the router what the password is. If you have the command "login" but no password, the router will have nothing to match, and therefore will not allow access. Look in your configuration under the vty lines. I'm sure you will see "login" but no password.

To correct:

config t

line vty 0 4

password XXXXX

end

copy run start

Re: Cisco 1720 password issue?

your line config should like like this

line vty 0 4

password telnetpassword

login

You get there from

enable

conf t

line vty 0 4

Hi,

this ocours because maybe you don´t have the telnet (line vty 0 4) password defined.

the reason the you are getting this message is that you have to have passwords set on the vty lines or you wont be able to telent in.
