Well-known addresses allow devices to reliably access switch services:
All services are addressed in the same way as an N_Port and
communicate using Fibre Channel frames.
Well-known addresses are the highest 16 addresses in the 24-bit fabric
address space.
The Common Transport protocol FC-CT (FC Level 3) is used when
accessing the Name Server, Time Server, Management Server, Alias
Server, and Key Distribution Server.
