Automatic configuration
This chapter includes these sections:
• Introduction to automatic configuration
• Typical automatic configuration network
• How automatic configuration works
Introduction to automatic configuration
Automatic configuration enables a device without any configuration file to automatically obtain and
execute a configuration file during startup. Automatic configuration simplifies network configuration,
facilitates centralized management, and reduces maintenance workload.
To implement automatic configuration, the network administrator saves configuration files on a server
and a device automatically obtains and executes a specific configuration file.
Typical automatic configuration network
Figure 63 Network diagram for automatic configuration
As shown in Figure 63 , the device implements automatic configuration with the cooperation of the
following servers: a DHCP server, TFTP server and DNS server:
• DHCP server—Assigns an IP address and other configuration parameters such as the configuration
file name, TFTP server IP address, and DNS server IP address to the device.
• TFTP server—Saves files needed in automatic configuration. The device gets the files needed from
the TFTP server, such as the host name file that saves mappings between host IP addresses and host
names, and the configuration file.
