28.5.2 Operation in multi-ring

The following figure shows an example of a multi-ring configuration that includes stacked nodes.

Figure 28-23: Multi-ring configuration without shared links including stacked nodes

Figure 28-24: Multi-ring configuration with shared links including stacked nodes

In a multi-ring configuration that includes stacked nodes, the following operations are the same as in a multi-ring configuration that does not include stacked nodes. For details, see 28.4 Overview of Multi-ring Operation.

• Normal ring operation

• Behavior when a fault is detected, except for a fault in the member switches that comprise the stack.

• Behavior when recovery is detected, except for a member switch failure that constitutes a stack.
