Changing a live two-unit stack to a linear-topology trunk

The ICX system performs numerous checks to block commands that could break a live stack. However, the checks have
limitations and may not catch all potential breaks. Therefore, you should verify the physical connections on the stack before
using the multi-stack-port or multi-stack-trunk command.
You can use the show stack connection command to check the physical connections of stacking ports (data port connections
are not shown).
In a live system, you can configure the desired trunk on both units simultaneously using the multi-stack-trunk command.
In the following procedure, an ICX 7250 two-unit linear-topology stack is created as an example. Each ICX 7250 device has two
potential linear-topology trunks, (x/2/1 to x/2/4) and (x/2/5 to x/2/8). When you configure either trunk, the system creates the
specified trunk on each unit and removes the other stacking direction.
1. Enter global configuration mode on the active controller.
