I have set a vty password and enable password for Cisco 2811 but after that when I take a tellnet connection the router asks Ciscon default username and password. ???


How can I disable these? I mean, when I connect with telnet, I don't want to log in with username and password.


I want that the router straight asks telnet password. So how to remove username and password?


Thanks for help. Sorry, this out of topic subject and bad English.

Can you post the configuration of your VTYs?


show run | section vty


if that does not work, try-


show run | begin vty

Hi,


If router is asking for Username and password at the time of login then some local user database configuration would have been done or aaa authentication would have been configured.If you want to disable the usernam prompt just remove the local username and password database which is configured in the switch and in line vty 0 15 just configure password "password name" .


Hope that help

2 ways to do this.  if you have not done a lot of configurations, you can erase the startup config and reload or you can do a -->no username from the CLI.

no aaa new-model

line vty 0 15

login

password XXXXXX

no exec-timeout

transport input telnet


This is not secure at all though.
