It is possible to create subsets of boxes and use different metadata channels (as well as boot loader image, boot image channels etc.) for the different subsets. This is achieved by delivering different DHCP option option-128 values from the DHCP to the different subsets. This allows the subsets to be configured differently concerning for instance portal URLs or the channel table.
N/A
host <name> {
hardware ethernet 00:02:9B:00:05:09;
option option-128 "224.2.2.17:21327";
}
or
subnet 222.222.5.0 netmask 255.255.255.0 {
option option-128 "224.2.2.17:21327";
option routers 222.222.5.1;
}
Note! The example is only valid if a
standard Linux DHCP-server is used
Note! The MAC address of the KreaTV IP-STB units in the subset can be obtained from the DHCP server log file when the KreaTV IP-STB requests an IP address. The MAC address can also be found on the label under the KreaTV IP-STB.
service infocastserverd restart
Note! Keep the notes under Managing an environment with redundant KreaTV Infocast Servers in mind if you have several active KreaTV Infocast Servers in your network.
The KreaTV IP-STB units in the new subsets use an alternative metadata channel, and optionally alternative object definitions after reboot.
