Hi, i've in a plant 4 IE-2000 switches where I need to connect a Siemens Simatic 400 H redundant system with remote I/O using Profinet.
Siemens stated that I need to use MRP for ring redundancy.
I've configured MRP with a switch as MRP Manager and the others as client.
The problem is that MRP ask for two ports on every switch but i need to connect Simatic CPU to two different switches: the cpus act in a strange mode because from every cpu i can contact MAC addresses of the two CPU so PVST+ and MRP try to fight for the control of the ports.
Searching over internet I only found a problem similar to mine here https://community.cisco.com/t5/switching/cisco-mrp-and-spanning-tree/td-p/2824667 with no solution!
