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 and maintenance.

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 41 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
2 minutes, and then automatically starts the process again for another try. The device continues to make
attempts until it gets a set of configuration settings or it is powered off.

Overall automatic configuration process

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

parameters for automatic configuration from a DHCP server.
Parameters for automatic configuration might include:
A temporary IP address.
A configuration file name.
A TFTP server domain name.
A TFTP server IP address.
