Created page with " In order to provide option 150 (or other custom options) two configuration entries are required, first, in the top level of the configuration file located at /etc/dhcp/dhcpd..."

New page

In order to provide option 150 (or other custom options) two configuration entries are required, first, in the top level of the configuration file located at /etc/dhcp/dhcpd.conf you need to define your custom option:

option voip-tftp-server code 150 = { ip-address };

Then, in the subnet stanza for where you need to provide the information you'll configure the option with the appropriate value.

subnet 192.168.0.0 netmask 255.255.255.0 {
[...]
option voip-tftp-server 10.101.0.10;
}

If you place the option definition in the subnet stanza then dhcpd will not work.

It can be:

option tftp-servers code 150 = array of ip-address;

option tftp-servers 10.20.10.1, 10.20.11.1;
