Configuring the IP Forwarding Service
Original instructions
About us
Introduction
The BMENOP0300 module includes an IP forwarding service. The IP forwarding service provides transparency between networks in a PlantStruxure system and can route packets among a maximum of two subnetworks that each has its own distinct broadcast domain.
The IP forwarding service is supported by the following versions:
NOTE: The recommended maximum throughput for the BMENOP0300 module that uses the IP forwarding service is 1,350 packets per second.
NOTE: Only one of the following functions can be enabled at any time: the IPsec protocol, the Ethernet backplane port, or the IP Forwarding service.
Use the configuration tool to configure the IP forwarding service by assigning unique IP address parameters (including the IP address and subnetwork mask) for the BMENOP0300 module to facilitate communications.
You can also identify the default gateway for the BMENOP0300 module. (Refer to the description of the role of the default gateway.)
NOTE: The default gateway is the IP address of the control network router. Usually this router is a device that connects the control network to other networks higher up in the Ethernet infrastructure.
