Creating Stacking Trunks On The Icx 7450 - Arris Ruckus ICX 7850 Series Configuration Manual

The following error message is displayed if stacking is configured on these ports and you enter the enable-mka ethernet
command for any of the ports.
Error: MACsec is not allowed when 4x10GF module is used for stacking.
Please configure "stack-port" or "stack-trunk" to change stacking ports.
The following example reconfigures stacking ports on slot 2 for use as MACsec ports.

Creating stacking trunks on the ICX 7450

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).
