We have a problem with 3com 4300 switches and mulicast in Zen 6.5.
We ahve just upgraded from Zen 3.2 to Zen 6.5
When doing a multicast from 1 pc to another our cisco switches work in
both pxe 3.2 and 6.5.
The 3com have now stoped working. When the session should start it does
not. It just sits there most of the time 95%. It does work 5% of the time.
Any suggestions please?
