Forgive me if this belongs somewhere else, but I could not find a Force10 forum. We have a 4820T pair configured as a VLT domain. Our "leaves" are Dell 5548s and 6224s connected via LAGs to the 4820T "spines". It seems in a failure scenario we cannot get our paths back up in less than about 7-8 seconds. In one of the white papers they were showing 1.5 sec path recoveries. What is the determining factor in getting a fast recovery? We have RSTP hello times etc dialed as low as they can go on the PowerConnects FWIW. Is there something else in say LACP etc that we have missed causing the path recovery to be slow?
