Good morning/afternoon,

I'm having an issue with an ICX 7750 configured for PIM 
Multicast.

Multicast streams are stopping after timeouts due to the 
7750 not sending out regular IGMP join packets for all of 
the streams in use.  It appears to only include 
approximately 20 or so when it should be sending out for 
150-100  different streams.

We've rebooted.  We're tried firmware 8.0.90k and 8.0.95k 
versions.  We've tried igmpv2 and v3.

Running debug statements, it appears that it thinks that it 
is sending it out for the various testing streams that we've 
worked with, but wireshark captures do not show the expected 
Join/Prune traffic.

The interface is a virtual interface that is connects to a 
single trunked interface with multiple VLANs.

Haven't found anything else yet.  Looking for any ideas.

Todd
