How Automatic Configuration Works
Introduction to Automatic Configuration
Automatic configuration enables a device to automatically obtain and execute the configuration file
when it starts up without loading the configuration file.
Automatic configuration simplifies network configuration, facilitating centralized management of
devices. Currently, enterprise networks are facing the problems of large distribution of devices and less
administrators, resulting in the huge cost for administrators to manually configure each device. With the
automatic configuration function, network administrators can save the configuration files on a specified
server and the device can automatically obtain and execute the configuration files, therefore greatly
reducing the workload of administrators.

server, TFTP server and DNS server:
DHCP server: Assigns an IP address, configure file name, TFTP server IP address, and DNS
server IP address for the device that performs automatic configuration.
TFTP server: Saves files needed in automatic configuration. A device obtains files needed from a
TFTP server, for example, network intermediate file and the configuration file of the device.
DNS server: Used for IP address-to-host name resolution. A device that performs automatic
configuration can resolve an IP address to a host name through a DNS server to get the
configuration file with the name hostname.cfg from a TFTP server; if the device gets the domain
1-1, the device implements automatic configuration with the cooperation of a DHCP
