I've had a working IGMP config in place for some time but multicast now seems to be flooding out every switchport (switches are all L3 cisco 4948E).
on each switch the config was:
and on the querier switch:
With this config, I found that running the command "sh ip igmp snooping groups" showed nothing, so I tweaked the config on each switch for vlan 1
I can now see switchports joining and leaving the groups when I start/stop streams on my machine, but multicast continues to flood out every port as though snooping is not working at all. If I switch off promiscuous mode in wireshark, I don't see multicast traffic captured.
Any recommendations?
