How automatic configuration works
Automatic configuration operates in the following manner:
1.
During startup, the device sets 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. If up Layer 2 Ethernet interfaces exist, the VLAN interface of the
default VLAN of the Ethernet interfaces is selected as the first up interface. Otherwise, the up Layer
3 Ethernet interface with the smallest interface number is selected as the first up interface.
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 factory default configuration.
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.
The configuration of these servers varies with device models and is omitted.
Before starting the device, connect only the interface needed in automatic configuration to the network.
