Figure 32 Automatic configuration workflow
Automatic-configuration parameter acquisition process
After the device finds an interface for automatic configuration, it enables the DHCP client on the interface.
Then, the DHCP client broadcasts a DHCP request to locate a DHCP server and request configuration
settings. The DHCP request contains DHCP Option 55, which indicates the configuration settings the
device requires, including the configuration file name, the TFTP server domain name, the TFTP server IP
address, and the DNS server IP address.
