I configured a VLAN with 2 ports on a Cisco 2960 48TT switch and connected a host to one port which is sending a number of unicast, multicast and broadcast UDP messages.
Next I connected an analyzer to the other port and observed the unicast and broadcast messages, but not the multicast messages.
Since the end host is not IGMP capable, I disabled IGMP snooping.
The VLAN was mirrored (span session) to another port on the switch and connected to an analyzer and the multicast messages were observed, so I am assured that the multicast messages are arriving at the VLAN but are not being flooded.
I ensured that unicast and multicast flooding was enabled and I disabled security for the ports on the VLAN.
From all the documentation that I have read on this switch, the multicast messages should flood if IGMP snooping is disabled.
Do I need to perform any other steps?
