Re: Can the Catalyst 3560 be configured to switch off MAC multi
>>C3560 supports IPv4 multicast routing or do you mean your traffic is encrypted in a way that the switch cannot understand upper layer protocols in the frame?
Correct, this is precisely what I mean.
However, I though that non-IP multicast traffic can be pruned using MAC addresses if CGMP or GMRP is used. So the alternative solution to IGMP snooping and IP Mulitcast routing is to use CGMP (client) or GMRP. This would pass the IGMP messages using a layer 2 protocol such as GARP.
However, I don't think these protocols are supported on the 3560 as the statement below shows that the 3560 uses IP multicast group based bridging rather than MAC address based bridging.

We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
