Trunking requirements
• 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 the table below.

• If you connect both ports in a trunk, both ports must connect to both ports of one trunk on another
device.
NOTE
If you use the Secure Setup utility to set up a mixed stack, the stacking units (ICX 6610 devices and
ICX 6450 devices) are automatically trunked.
Ports used to connect ICX 6610 devices to ICX 6450 devices
There are eight SFP+ ports in slot 3 on the front panel of an ICX 6610 device that are used to connect
ICX 6610 devices to ICX 6450 devices in a mixed stack. The first figure below shows the 10 Gbps SFP+
ports in slot 3 of a 24-port device. The second figure below shows the 10 Gbps SFP+ ports in slot 3 of a
48-port device.
Without a license at bootup, the SFP+ ports come up in 10 Gbps port speed in an error-disabled state.
To enable the SFP+ ports to 10 Gbps port speed, you must purchase the ICX6610-10G-LIC-POD
license for each ICX 6610 SFP+ port that connects to an ICX 6450 device.
Maximum number of ports you can use on an ICX 6610 device to connect to ICX 6450 devices
Any one ICX 6610 device supports a maximum of:
