Creating Stacking Trunks on ICX 7450 Devices
The ICX 7450 supports two stacking trunks per stack unit when the 4X10GF module in
slot 2 is used for stacking.
You can configure one or two stacking trunks on an ICX 7450 stand-alone as shown in the following example. Each stacking trunk can have two ports. Potential stacking trunks contain the stacking port and the next sequential port (1/2/1 through 1/2/2 and 1/2/3 through 1/2/4).
Note: Valid-stack-ports 1/3/1 and 1/4/1, which are 40-Gbps ports on the rear panel of the
ICX 7450, do not support stacking trunks.
Note: ICX 7450-24P devices support linear-topology trunks in a two-unit stack. In an ICX
7450-24P linear-topology trunk, you can configure ports 1/2/1 to 1/2/4 or ports 1/3/1
and 1/4/1 in one trunk. Refer to
Support for two-unit stack linear-topology trunks for more information.
The following example configures two stacking trunks.

Creating Stacking Trunks on Live Stacks
Use the
multi-stack trunk or
multi-stack port
command to add or remove a stacking trunk on a live ICX 7450 stack. The following
example creates two stacking trunks.
