Logging in through modems

Introduction

The administrator can use two modems to remotely maintain a switch through its AUX port over the Public
Switched Telephone Network (PSTN) when the IP network connection is broken.

Configuration requirements

By default, no authentication is needed when you log in through modems, and the default user privilege
level is 3.
To use this method, perform necessary configurations at both the device side and administrator side.
