Telnet problem

When I attempt to telnet to a remote switch, the session skips past the passwords, and in the terminal window I get a message that indicates "bad passwords", then the session terminates. I can log on to the console. I have verified the configuration for the "vty" ports. Login is specified as well as a password. If I remove this password, then the telnoet session indicates, as it should that a password is required but not set. As soon as I set a password, the symptom returns. The screen capture below shows the output.

User Access Verification

Password:

Password:

Password:

% Bad passwords

Connection to host lost.

Any Ideas?

Re: Telnet problem

make sure that you have the password the same on ALL vty lines ,

what does the config of the vty lines look like

Re: Telnet problem

Looks like an incorrect session setting.

Please try a different terminal type in your emulation. (i.e. VT220, VT320)

Disable anything with graphic characters.

You could also try a different telnet program.
