How automatic configuration works Automatic configuration works in the following manner: 1. During startup, the device sets the first up interface (if up Layer 2 Ethernet ports exist, the VLAN interface of the default VLAN of the Ethernet ports is selected as the first up interface.) as the DHCP client to request parameters from the DHCP server, such as an IP address and name of a TFTP server, IP address of a DNS server, and the configuration file name. 2. After getting related parameters, the device sends a TFTP request to obtain the configuration file from the specified TFTP server and executes the configuration file. If the client cannot get such parameters, it uses the factory defaults. To implement automatic configuration, you must configure the DHCP server, DNS server, and TFTP server, but you do not need to perform any configuration on the device that performs automatic configuration. Before starting the device, connect only the interface needed in automatic configuration to the network. Automatic configuration work flow Figure 44 shows the work flow of automatic configuration.

How automatic configuration works
Automatic configuration works in the following manner:
1.
During startup, the device sets the first up interface (if up Layer 2 Ethernet ports exist, the VLAN
interface of the default VLAN of the Ethernet ports is selected as the first up interface.) as the DHCP
client to request parameters from the DHCP server, such as an IP address and name of a TFTP
server, IP address of a DNS server, and the configuration file name.
2.
After getting related parameters, the device sends a TFTP request to obtain the configuration file
from the specified TFTP server and executes the configuration file. If the client cannot get such
parameters, it uses the factory defaults.
To implement automatic configuration, you must configure the DHCP server, DNS server, and TFTP server,
but you do not need to perform any configuration on the device that performs automatic configuration.
Before starting the device, connect only the interface needed in automatic configuration to the network.
