I could do with some help. I have two 4500 on separate networks, about 700 machines per network. They are both identical? hardware with supervisor IV engines and latest, April this year software. The config files match line for line. I have enabled ip igmp snooping on both, but only one populates the mac table. The other only has two batches of system macs listed. The network clients are identical - all run RedHat Enterprise 32bit.
I know I have said they are both the same but obviously they are not otherwise they would both route multicast.
Multicast is not the greatest topic, but can anyone give me an idea where to look for the problem. I thought I could flatten the duff switch but none of the commands appear to work. The bios proms are the same but very early revisions.
