Step Command Remarks
13. Set the intended bandwidth
for the asynchronous serial
interface.
bandwidth bandwidth-value Optional.
14. Restore the default settings for
the asynchronous serial
interface.
default Optional.
15. Shut down the asynchronous
serial interface.
shutdown
Optional.
An asynchronous serial interface is
up by default.
NOTE:
• You can use the speed command in interface view to confi
g
ure the baud rate for an asynchronous serial
interface. For more information, see
Fundamentals Configuration Guide .
• Configure PPP, DCC, IP address, firewall, and backup center for the asynchronous serial interface if the
network requires.
Configuring an AUX interface
The AUX interface is fixed on your device. It can operate as a regular asynchronous serial interface at a
speed up to 115200 bps. With this interface, you can perform functions such as remote device
configuration and line backup.
To perform other AUX interface configurations (such as baud rate, stop bit, parity, and flow control), use
the corresponding commands in user-interface view. For more information, see Fundamentals
Configuration Guide.
Configuration procedure
To configure an AUX interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter AUX interface view.
interface aux interface-number N/A
3. Set the interface description.
description text
Optional.
By default, the description of an
AUX interface is interface name
Interface, for example, AUX0
Interface.
4. Set the operating mode.
async mode { flow | protocol } The default is the flow mode.
5. Enable level detection.
detect dsr-dtr
Optional.
Enabled by default.
6. Enable local loopback.
loopback
Optional.
Disabled by default.
