Isolating Specific Hub Connections

You can interconnect or isolate the hubs in a stack using a multi-segment configuration. In a stacked system, some hubs may be connected to a segment while others are isolated (not attached to any segment). In this example, hubs 1 and 2 are attached to segment 1, while hubs 3 and 4 are attached to segment 2. However, hubs 5 and 6 are not connected to any segment. These hubs form isolated segments. With careful planning, you can restrict access for specific user groups to required connections only.
