Brocade ICX 6610 Stackable Switch Hardware Installation Guide - Manual (Page 52)

For example, substacks 1 and 2 have ports in VLAN 10, 11, 12, and 13. In this case, you should
arrange the VLAN port association so that substack 1 ports are in VLAN 10, 11, and 12, and
substack 2 ports are in VLAN 12 and 13. Such an arrangement avoids flooding packets in VLAN
13 to substack 1, and also avoids flooding packets in VLAN 10 and 11 to substack 2.
• A ring is a more resilient topology than a linear topology.
• If there are two backbone devices, link substacks to both backbone devices.
• To prevent traffic congestion and avoid potential latency issues, keep substacks small, especially
in linear topologies.
Connecting ICX 6610 devices in the backbone
The following figure shows how to connect ICX 6610 devices in a mixed stack backbone using both
ports (ports 1 and 2) in trunk 0 of each ICX 6610 device. Ports 1 and 2 in the top device connect to
ports 1 and 2 in the bottom device, respectively.

Connecting a peripheral device to an ICX 6610 and to another
peripheral device
The following figure shows how to connect an ICX 6610 device in the backbone to an ICX 6450
peripheral device. It also shows how to connect two ICX 6450 peripheral devices to each other. Both
ports in each ICX 6450 trunk are used.
One trunk (ports 1 and 2) in the middle ICX 6450 device is used for the upstream link to the ICX 6610
device. The other trunk (ports 3 and 4) in the middle ICX 6450 device is used for the downstream link
to the second ICX 6450 device.
The ports or trunk on an ICX 6610 device that connect to a peripheral device are called peripheral
ports or a peripheral trunk, because they link to ICX 6450 peripheral devices. The first port in a
