Switch Configuration
n
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. Refer to Table 13 for the information about authentication mode configuration.
