A policy must be set that limits connectivity to only the switches within the same fabric. Fabric
binding is a security method for restricting switches that may join a fabric. For Fabric OS
switches, fabric binding is implemented by defining a switch connection control (SCC) policy
that prevents unauthorized switches from joining a fabric.
•
Dynamic Load Sharing (DLS) should be disabled. If DLS is not disabled, DLS automatically
adjusts routes when a new ISL is added, and when an ISL is taken offline and brought online
again. This process may result in dropped frames.
NOTE
Port binding is a security method for restricting devices that connect to particular switch ports. Port
binding should never be used in FICON environments. The FICON channel cannot be added to the
port binding list.
