Configuring 10-Gbps Stacking Ports on ICX 7450 Devices

By default, the ICX 7450 uses 40-Gbps ports in slots 3 and 4 as stacking ports. When a 4X10GF module is installed in slot 2 on the front panel of an ICX 7450, 10-Gbps stacking can be configured.
Note: Stacking and MACsec cannot be configured on these 10-Gbps ports at the same time. Refer to Converting ICX 7450 slot 2 ports for MACsec or stacking for more information.

To configure stacking on 10-Gbps ports in a 4X10GF module installed in slot 2, configure use the stack-port or stack-trunk command to configure stacking ports or trunks as shown in the following example.

Once the stack-ports are configured, enter the write memory and then the reload command, after which the unit is ready to join an existing stack or to be configured for stacking using stack interactive-setup or manual stack construction.

Note: You must enable stacking with the stack enable command before you can initiate stack interactive-setup or construct a stack.

Note: Changing the stack-port configuration and entering the reload command are not required for a unit to be discovered by stack interactive-setup or stack zero-touch provisioning. However, you must reload the prospective active controller after its stacking ports are changed before you initiate stack interactive-setup or stack zero-touch provisioning from that unit. The units to be discovered do not need to configure anything or reload. The active controller reloads them as members after they are discovered.

Note: If you use the manual construction method, you must reload every unit if you have changed stacking ports 1/3/1 and 1/4/1 to ports on slot 2.
