Hi Peter, We have two 4 port EA's in our 8730 with all eight paths active. That is to a mainframe though with all devices mapped to all ports. What is your current RDF infrastructure? dark-fibre, managed service etc? Have you considered ISLing your RDF traffic using a FA port (configured as RA) instead? We've been runing that configuration very successfully for the past couple of years. Like I mentioned earlier, depending on your link. Any more questions just ask. Brian.
