. FICON configurations There are two types of FICON configurations that are supported using Brocade Fabric OS: switched point-to-point and cascaded topologies. Switched point-to-point A single-switch configuration is called switched point-to-point and requires that the channel is configured to use - HP 1606 | FICON Administrator's Guide v6.4.0 (53-1001771-01, June 2010) - Page 19

For Brocade M-Series directors or switches, this is known as SANtegrity Binding, and it requires M-EOS firmware version 4.0 or later.
