In " sh run " there is as such no configuration for "line vty 5 15 " is it possible that this command is hidden ?
can i do this "i will log in device using console , then i attempt to telnet X.X.X.X 22 then can i check on which line it is trying to connect ?" is it possible , if yes then which command to execute to check ?
By setting the line vty transport to none, the Cisco device will no longer respond to telnet sessions. Because the device will not respond to these protocols, you will get a blank screen if you try to telnet to the device.
The only way that I am familiar with not allowing telnet access but giving some type of error message when it fails is to first enable telnet on the line vty transport. Then remove any enable and enable secret passwords on the device. Now when anyone attempts to telnet to the device, it will kick the person out with the error that no enable password has been set.
This will of course required that the device be in a locked environment so not just anyone can console into the device, hopefully you already have this setup.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
