Figure 64 Work flow of automatic configuration
Using DHCP to obtain an IP address and other configuration
information
Address acquisition process
As mentioned before, a device sets the first up interface as the DHCP client during startup. The DHCP
client broadcasts a DHCP request, where the Option 55 field specifies the information that the client
wants to obtain from the DHCP server such as the configuration file name, domain name and IP address
of the TFTP server, and DNS server IP address.
After receiving the DHCP response from the DHCP server, the device obtains the IP address and resolves
the following fields in the DHCP response:
Option 67 or the file fieldObtains the configuration file name. The device resolves Option 67 first.
If Option 67 contains the configuration file name, the device does not resolve the file field. If not, the
device resolves the file field.
Option 66Obtains the TFTP server domain name
Option 150Obtains the TFTP server IP address
Option 6Obtains the DNS server IP address.
If no response is received from the DHCP server, the device removes the temporary configuration and
starts up with factory defaults.
