NOTE
If you receive a 'FICON not supported on switch' error, refer to FICON troubleshooting for a list of
possible causes.
If you want to join two cascaded FICON fabrics, they must be merged. If the distance between
fabrics is 10 km or more, an Extended Fabrics license is required, and an extra step is required to
