To choose an IP addressing scheme
Carefully plan your addressing scheme to avoid duplicate IP addresses.
If there is a DHCP server on the network, and, if you have a single controller or multiple controllers that exist
on the SAME subnet, use DHCP addressing. Skip to the section
To obtain an IP address using DHCP
(page
If you have multiple controllers that reside on different subnets, you cannot use DHCP addressing. Instead,
give each controller an assigned IP address. Skip to the section
To assign a custom IP address
(page 10).
NOTE
This network configuration also requires that you configure IP Broadcast Management Devices
(BBMDs). See To set up BACnet Broadcast Management Devices.
