Figure 3. Duplex-ring Topology
Both topologies offer the same in terms of network speed and
performance. But the duplex-ring topology adds redundancy by providing
a secondary path through the stacking modules. This can protect a stack
against the failure of a stacking port or cable. A disruption in the primary
path automatically activates the secondary path.
