Ports used to connect ICX 6610 devices in the backbone
The ICX 6610 device contains four ports in slot 2 on the rear panel that are dedicated stacking
ports. They cannot be used as data ports, even when stacking is not enabled. There are two
40 Gbps ports and two 4 x 10 Gbps ports arranged in two rows.
The stacking ports can be grouped into two trunks. Ports 1 and 2 on the top row can form trunk 0;
ports 6 and 7 on the bottom row can form trunk 1.
You can trunk stacking ports by connecting one port of each type (40 Gbps or 4 x 10 Gbps) to ports
of the same type on another ICX 6610 device in the stack.

Dedicated stacking ports and trunks on the rear panel of an ICX 6610 device
Port 1, 40 Gbps
Trunk 0
Port 2, 4 x 10 Gbps
You can connect one or both ports in a trunk. Connecting both ports in a trunk increases
stacking bandwidth and provides resiliency.
You must connect each port type (40 Gbps or 4x10 Gbps) to the same type of port on another
device, as shown in Table
Port connections for trunking between ICX 6610 devices
Valid port connections

Port 1 to Port 1
Port 1 to Port 6
Port 2 to Port 2
If you connect both ports in a trunk, both ports must connect to both ports of one trunk on
another device.
