Introduction
You may log in your switch from its console port from a remote device across a PSTN with a pair of
modems in between. When your switching network fails, this allows you to remotely configure your
switch, retrieve logs and warning messages, and locate the problem.
To log in to your switch in this way, you need to configure the terminal and the switch properly, as listed
in the following table.
