What is the maximum hop count of fabric switching?

The maximum hop count on fabric switching is a total of 3 hops. When a host transmits, it will enter a Leaf switch; the Leaf switch will then forward traffic to the Spine switch. The Spine switch will in turn forward traffic to the corresponding Leaf switch and to the destination host. Of course, traffic could be 1 hop away, if both hosts are on the same Leaf switch. However, the maximum hop count is 3 hops.
