SummitStack nodes should be connected to each other in a ring topology. In a ring topology, one link is used to connect to a node and the other link is used to connect to another node. The result forms a physical ring connection. This topology is highly recommended for normal operation.
Graphical Representation of a Ring Topology represents a maximal ring topology of eight active nodes.
Each switch in a rack is connected to the switch above it and the switch below it. To complete a ring, a longer cable might be needed to connect the top switch to the bottom switch.
Note that, while a physical ring connection may be present, a ring active topology exists only when all nodes in the stack are active.
