When DHCP autoconfiguration is Enabled, the Switch becomes a DHCP client autom atically after rebooting. The
DHCP server must have the TFTP server IP address and configurat ion file name, and be c onfigured to deliver this
information in the data field of the DHCP reply packet. The TFTP server must be running and h ave the requested
configuration file in its base directory when the request is received from the Switch. Consult the DHCP server and
TFTP server software instructions for information on loading a configurati on file.
If the Switch is unable to complete the autoconfiguration process the previously saved local configurat ion file present
in Switch memory will be loaded.
