Hello - I'm new to this, and I’m trying to conduct a simple test on a Summit X670 switch running EXOS 15.5. I want to use the UFTP program to send files from one Windows sender to multiple Ubuntu receivers. The program uses multicast for sending files. All computers are on the same switch, and since all ports are on the Default VLAN together, my understanding is that no configuration with PIM or MVR is needed. However, the multicast traffic isn't reaching the destinations, according to Wireshark.
Is there anything I might need to do on the switch to get it to forward the traffic? Are there any monitoring commands I can employ to debug this?
