Connecting Icx 6610 Devices In The Backbone; Connecting A Peripheral Device To An Icx 6610 And To Another Peripheral Device - Brocade Communications Systems ICX 6430 Hardware Installation Manual

Topology recommendations
Consider these factors when you implement a topology:
• Limit the number of VLANs of peripheral devices to reduce broadcast and multicast packets flooding to the peripheral devices.
• Broadcast and multicast packets of a VLAN are flooded to a substack if the substack has any ports in the VLAN. For this
reason, you should limit (localize) VLAN association of substack ports.
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 topology is more resilient 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 peripheral trunk on a backbone device and the first port in a stack trunk on a
peripheral device must be an odd-numbered port, for example, 1/3/1 or 3/2/1.
