very basic setup. two servers on the SAME vlan 11 on the SAME switch (C6500-sup720 IOS 12.2(18)SXF13)
it's a layer 2 vlan. switch doesn't have a layer 3 SVI "int vlan11" on this vlan
Both hosts are publishing to a multicast address (verified by wireshark) but they're not receiving data. I suspect IGMP join is not set up correctly on the application itself...
but is there any way on Cat6500 to display multicast groups and show that "your host is not igmp joining the multicast group at all!"
"sh ip igmp groups" would only display multicast groups layer 3-routed. nothing from vlan 11
