The configuration commands and the output of different Modems may differ. Refer
to the user manual of the Modem when performing the above configuration.

4.3.2 Switch Configuration

Note:
After logging into a switch through its console port by using a Modem, you will enter the
AUX user interface. The corresponding configuration on the switch is the same as
those when logging into the switch locally through its console port except that:
When you log in through the console port using a Modem, the baud rate of the
console port is usually set to a value lower than the transmission speed of the
Modem. Otherwise, packets may get lost.
Other settings of the console port, such as the check mode, the stop bits, and the
data bits, remain the default.
The configuration on the switch depends on the authentication mode the user is in.
