hi, i have trouble with a stack of 5548p.
i'm running 7 schools with multicast announcement. with one of them, setup exactly as the others (same firmware, same config appart from vlan and igmp group address).
it looses igmp registration (as in, no more listed in show ip igmp snooping groups, except from one port)
and there is absolutly nothing in the debug logs. i even replaced the switchs thinking it was a faulty master switch (behaved weirdly...)
core is a stack of 8164f, pim-SM and igmp.
stack is two 5548p, latest firmware, igmp snooping and bridge multicast filtering.
dont know what to check. only way to restore the groups is to reload the stack. resetting a phone does nothing.
anyone have a hint, i'm losing hair over this... thanks a lot.
