used for many or any clients. The hm option is a MAC address mask used to determine if the MAC
address of the requestor matches the MAC address of the ha bootptab option.
ha=000000000000:\
hm=000000000000:\
bp=10.2.1.11
Note that care is needed if the system is connected to multiple subnets, since the bootp relay
helper will respond to boot requests detected on any NIC. Make sure the correct server is set and
any network routing is configured as described in “Having the client contact the correct server”
(page 55) and “Install remote clients through a network router” (page 54)
See bootpd(1M) for details of configuration.
Note that this approach works for PA-RISC systems but might not work for Integrity systems. For
Integrity systems, the HP-UX boot loader configures the bootp relay boot helper as a gateway
system for network configuration. If that system does not route packets between subnets, this might
impede successful use of this approach. If the system routes packets, it will be attached to multiple
subnets and therefore respond to boot requests detected on multiple subnets.
Ignite-UX software does not have to be installed on the bootp boot helper.
The following is an example of a local bootp relay boot helper /etc/bootptab content to
respond to any client MAC address:
bootp-relay:\
ht=ether:\
ha=000000000000:\
hm=000000000000:\
bp=15.2.1.11
The following is an example of selective, MAC-specific /etc/bootptab content:
hpfcixa:
ht=ether:\
ha=001083352de5:\
bp=15.2.1.11
A block of MAC addresses may be specified using the ha and hm options. This approach might
be very useful with HP systems supporting HP Virtual Connect technology.
The master Ignite server needs to have entries for the client system boot requests forwarded from
the bootp forward boot helper:
ignite-defaults:\
bf=/opt/ignite/boot/nbp.efi:\
ht=ethernet:\
hn:\
bs=48:\
dn=xyzco.com:\
gw=10.4.1.1:\
sm=255.255.255.0:\
ds=10.2.1.11
hpfcixa:\
ht=ignite-defaults:\
ha=001083352de5:\
ip=10.4.1.100:\
bp=10.2.1.11
To use the bootp relay boot helper with PA-RISC systems, boot using standard ports, such as:
boot lan.10.2.1.11
The installation option to use HP-UX specific network ports might not work:
boot lan.10.2.1.11 install
