Hi,

I trying to found information if could be any problem to enable multicast filter ( filter 01:0E:CF:00:00:00 ) on ports 9 and 10to filterprofinet protocolon X308-2 ring structure, I should have only TCP protocol on this ring ! The redundancy manager (RM) will continue work without problem ? We'll use the web diagnostics funtionality on this ring too!

Thanks in advance

"The ring ports send multicast frames at cyclic intervals to detect line breaks. For port blocks

that contain ring ports, you should therefore not limit the receipt of multicast frames to ensure

that the redundancy manager functions correctly."

Perhaps the manual "SIMATIC NET Industrial Ethernet Switches SCALANCE X-300 SCALANCE X-400 Configuration Manual" helps you to configure the SCALANCE X308-2. You can find it here:
