An important point to keep in mind is that by default, the multicast collision detection packets have a TTL of 1; i.e. they won't span subnets.
For LDoms automated MAC address collision to work across subnets, your network switches & routers need to be configured to forward multicast, and the TTL needs to be adjusted as mentioned in the Admin Guide, to wit: By default, these multicast messages are sent only to other managers on the same subnet; the default time-to-live (TTL) is 1. The TTL can be configured using the Service Management Facilities (SMF) propertyldmd/hops. -Eric On Aug 13, 2009, at 1:15 PM, Octave Orgeron wrote: > > > When MAC addresses are assigned, LDM will attempt to prob the > network to make sure there isn't a MAC conflict.
