Hi This is a good way to connect the two stacks together as you can configure the link as a 4 X 10gig link aggregate. You should use LACP rather than static, so that any failing link is quickly identified, and so will be dropped out of the aggregate.
[IMAGE] I have an M1000e with 2  x M8024-k switches (stacked) in B1 and B2 slots, I have connected them to the rack switches via 10gbe ports to the 2 x N3048 (Stacked)   Is this the best way to connect?  And how should I add or number the LAG connections as none of them are attached to the same switch?    Many thanks                                                                                                                                               Stack   
Best cabling for blade M8024-k switch stack to ToR N3048 using 10GBe modules?
