Figure 12. Stack of Four Switches in the Linear Topology

The second topology is called the ring topology. It is similar to the linear topology, except that the unused stacking ports on the end switches of the stack are connected to form a physical loop. This topology is more resilient than the linear topology because there are two pathways through the stack. If one pathway fails, the switches can maintain communications through the alternate pathway. The example in Figure 13 on page 46 shows a ring topology of two switches.
