Using automatic configuration

With the automatic configuration feature, the device can automatically obtain a set of configuration
settings from some servers when it starts up without a configuration file. This feature simplifies network
configuration, facilitates centralized management, and reduces maintenance workload.

Understanding automatic configuration

The automatic configuration feature requires the cooperation of the following servers: a DHCP server, an
HTTP server, a TFTP server, and a DNS server, as shown in
Figure 36 Typical automatic configuration network diagram
When the device is powered on without a configuration file, it automatically starts the automatic
configuration process to try to obtain a set of configuration settings. If one attempt fails, the device waits
30 seconds, and then automatically starts the process again for another try. The device continues to
make attempts until it obtains a set of configuration settings. To stop the process, power off the device or
press Ctrl+D.

Overall automatic configuration process

As shown in
1. The device selects an interface for automatic configuration. For more information, see
