Figure 17. 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 slots 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 18 on page 52
shows a ring topology of two switches.
