New features and bug fixes

Improvements

Network Essentials

IE3400 HSR-PRP Support

This feature, also called Dual RedBox mode, is used to bridge HSR and PRP networks.

IE3x00 and IE31xx Delayless IPDT

This feature allows faster processing of ARP packets in a network with IP Device Tracking (IPDT) enabled.

Industrial Asset Discovery (IAD)

IAD uses discovery messages included in industrial protocols such as CIP and Profinet to discover directly connected end devices.

IE3x00 L3NAT for IOx Applications

This feature allows an IE3x00 switch with a single public routable IP address to support an IOx application that can use a private IP address. L3NAT is only applicable to IOx applications as defined in the guide listed to the right, not for general use.

gRPC mTLS Stream Telemetry support for IE Switches

gRPC is a remote procedure call developed by Google for low-latency, scalable distributions with mobile clients communicating to a cloud server. The gRPC plugin is enabled on Model Driven Telemetry (MDT).
