Securing VTY Access Using a Telnet Password
By default, all Cisco routers support up to five simultaneous Telnet sessions, and by default, no passwords are assigned to these Telnet or VTY lines. There is builtin security on the VTY lines that mandates the use of passwords to access the router via a Telnet session. If a Telnet session is initiated to a router that does not have a password assigned to the VTY lines, the following message

appears on the screen:
telnet 172.31.100.11
Trying...
Connected to Escape character is 'Password required, but not set
Connection closed by remote host
Figure 3.4
shows how Telnet behaves when there is no password and login assigned to the VTY lines.
