HP 10500 Series Configuration Manual page 211

To use the host name file network.cfg, create a configuration file for each device on the TFTP server,
name the file in the format host name.cfg, and add a mapping entry in the format ip host host-name
ip-address for the host name file. For example:
ip host host1 101.101.101.101
ip host host2 101.101.101.102
ip host client1 101.101.101.103
ip host client2 101.101.101.104
If a device resides in a network different than the TFTP server, configure the UDP helper function on the
gateway so the gateway changes the broadcast TFTP request from the device to a unicast packet and
forwards the unicast packet to the TFTP server. For more information about UDP helper, see Layer 3—IP
Services Configuration Guide.
