Executing The Configuration File - HP 5830 Series Configuration Manual

If the IP address and the domain name of the TFTP server are not contained in the DHCP response
•
or they are illegitimate, the device broadcasts a TFTP request.
After broadcasting a TFTP request, the device selects the TFTP server that responds first to obtain the
configuration file. If the requested configuration file does not exist on the TFTP server, the request
operation fails, and the device removes the temporary configuration and starts up with null.
If the device and the TFTP server reside in different subnets, configure the UDP Helper function for the
gateway to change the broadcast TFTP request from the device to a unicast packet and forward the
unicast packet to the specified TFTP server. For more information about UDP Helper, see Layer 3—IP
Services Configuration Guide.

Executing the configuration file

After obtaining the configuration file, the device removes the temporary configuration and executes the
configuration file. If no configuration file is obtained, the device removes the temporary configuration
and starts up with null.
The configuration file is deleted after executed. Save the configuration by using the save command.
Otherwise, the device has to perform automatic configuration again after reboot. For more information
about the save command, see Fundamentals Command Reference.
