Hi All,   I wonder if anyone can pass on some advice on the follow topology please?   We are looking at a Core switch design as shown below, using MS425’s and MS225’s The plan now is to use Flexible stacking QSFP between the two MS425’s and also have the MS225 connected as a physical stack with a single 10Gb uplink each of the two MS225’s back the MS425’s.     My question is can/should we create a Link Aggregate as well using the two 10Gb uplinks, knowing that we have the MS425’s Flexible stacked and all the MS225’s configured as a stack as well?   Our original approach was to have the Link Aggregate between MS425’s and MS225’s, but not have the MS425’s Flexible Stacked via QSFP.   Any thoughts on this please. Thanks in advance.   BB ... View more
