Hi!
I have problem to get multicast working on my CBS350-24FP-4X. I made it according Cisco`s youtube video CBS Switch Multicast Forwarding Using IGMP Snooping. Only thing that differs is that I changed interface default settings (ports and VLAN) to v2 and default query interval to 60 seconds. I monitored traffic with Wireshark and when I made videos configuration, everything seemed to work fine. When I changed interface settings to v2 and query interval, Multicast (that should not be stopped) seemed to stop flowing.
To explain it little bit more, I have AoIP devices connected to switch and they do discovery via mDNS 224.0. 0.251. I also added address to IPv4 Multicast Group Addresses and it did not have any effect. My controller does not see devices. I can ping those, so they are present, but not visible. Wireshark does not show any IGMP messages.
Devices:
Cisco CBS-24FP-4X
Firmware 3.3.0.16
Dell Latitude 5530 with Win 10 build 19045.
Any ideas what might be the issue? I have done same stuff on Cisco SG350 and those work just fine. I know that there is similar post on this forum, but it does not have had any answers and seems to be little different. I also tried what that post tried, not to filter unregistered multicast, but it did not help.
