Explanation:
There are a total of 5 logical Virtual terminal interfaces in a Cisco router (lines 0-4) and they are
used for remote access into the device via telnet. Configuring these interfaces correctly with a
login and password information can be used for security, as each user will be prompted for a
password in order to obtain access. A second method is to use the “access-class” command.
Combined with an access list, this command can be used to specify the hosts or networks that will
be allow access to the device.
