Description (partial)

A multicast source feed is received on a Nexus 3000 from a directly connected server does not get flooded out the mrouter port to the PIM-DR. It gets silently dropped.

Issue occurs when the mrouter port is a port channel with "hardware multicast hw-hash" added under the interface config and the switch is then upgraded to 6.0(2)U2(2).  After the upgrade that line will be missing from the running config.
