Hello,
I am testing access switches for one project, I notice when i telnet from core to access and instead of appropriate username if i give some junk characters like shown in below output. Its accepting that username and not asking for password and landing me to the user-exec (>) mode.
CORE-SW#telnet 192.168.1.50
Trying 192.168.1.50 ... Open

Username: aldkfjadfdslkdja
