LMS2.2 recognises CSS's with WebNS v7.3 but not v7.4.I've noticed that the OUID changes with v7.4.Is there a simple answer/fix for this?Thanks

Hope someone can help...I've set up 2 3750's with common vlans and trunks back to a pair of 6506's acting as a backbone. Unicast/Broadcast traffic between servers on the same lans on both 3750's is ok.Set up igmp snooping on all devices. No multicast...
