Connecting devices in a mixed stack
FIGURE 40 Topology 3: Linear and ring
Topology 4: Ring with one backbone device
In the following figure, one ICX 6610 device forms the backbone, and there are six ICX 6450 peripheral devices in a ring topology. One
substack that contains all six peripheral devices.
Topology 4 shows that you can have a mixed stack with only one ICX 6610 device, although this configuration does not provide high
availability or resiliency for the stack because there is no standby controller.

Topology recommendations
Consider these factors when you implement a topology:
• Limit the number of VLANs with peripheral devices to reduce broadcast and multicast packets flooding to the peripheral
devices.
