HP 5800 Series Configuration Guide

178
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 factory defaults.
If the device and the TFTP server reside in different subnets, you must 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 factory defaults.
The configuration file is deleted after executed. Save the configuration by using save. Otherwise, the device
has to perform automatic configuration again after reboot. For more information about save, see
Fundamentals Command Reference.
