HP-UX IP Address and Client Management Administrator's Guide (October 2009)

dhcpv6clientd updates the /etc/dhcpv6client data file with information obtained from
the server.
The dhcpv6db2conf Utility
/usr/sbin/dhcpv6db2conf is a utility that interprets the contents of the
/etc/dhcpv6client.data file into a readable format.
You can use dhcpv6db2conf to complete the following tasks:
• List the contents of the client database to the screen.
• Create a set of configuration-staging files or edit the existing configuration files using the
values that the client database contains.
The dhcpv6config script invokes dhcpv6db2conf when the dhcpv6client.data file has
new or updated information.
Alternatively, run the following command on the command line to invoke dhcpv6db2conf
and to specify a list of interfaces:
# dhcpv6db2conf [-a | -c | -p] [-d] [-i] [-n] [-s] [-v]
[lan_interfaces]
where,
-a
Using the results of the specified filter, directly apply the variable
definitions to the existing configuration files (for example,
/etc/rc.config.d/netconf-ipv6).
—c
Create a set of staging files using the results of the selected filters.
—d
Process the DNS variable set: [domain, nameserver].
—i Process the INTERFACE variable set:
[IPV6_SECONDARY_INTERFACE_NAME, IPV6_ADDRESS,
IPV6_PREFIXLEN, DHCPV6_ENABLE].
—p Print results to the screen (stdout), this is the default action if neither -c
nor -a are specified.
—n
Process the SIP server address and SIP domain name information.
—s Process the NIS variable set [NIS_DOMAIN, YPSET_ADDR].
—v
Process the vendor-specific information.
lan_interfaces Specifies LAN interfaces such as lan0, lan1, whose data must be
translated to a readable format. If you do not specify the LAN interface,
dhcpv6db2conf processes the entries of all interfaces which are UP.
When you invoke dhcpv6db2conf with the -a option, dhcpv6db2conf updates the
/etc/resolv.conf, /etc/rc.config.d/netdaemons/,
/etc/rc.config.d/netconf-ipv6, and /etc/rc.config.d/namesvrsfiles.
For more information, type man 1 dhcpv6db2conf at the HP-UX prompt.
Configuring a Relay
This section describes how to configure a host as a DHCPv6 relay. To configure a host on the
DHCPv6 network to function as a relay, set the following tags in the /etc/dhcpv6tab file:
• DHCP_RELAY_SETTINGS;
This tag indicates the start of the DHCPv6 relay settings.
• subnet-prefix
This tag specifies the IPv6 subnet prefix in hexadecimal notation in the form
address/prefix-length.
