Hello,

I have some multicasting issues with the HP switch we are using. When one of the 2 sunray server in the failover load-balanced group is sending a multicast message, then the switch is dropping unicast packets to that host for 10/20 seconds L Disabling IGMP solves the problem but it is not really ideal.

When we are using wireshark or snoop on the solaris 10 05/08 (with SRS4) sunray server, we can observe that Solaris is duplicating the sunray multicast messages on the primary public interface!! Is this normal ? This strange behavior could be triggering a bug on our HP switch.

The Sun Ray server software sends multicast heartbeat packets on all of the real interfaces on the host. It's how it discovers the connectivity of the servers.
