The FC8-16, FC8-32, FC8-48, and FC8-64 supports these
port types:
F_Port, E_Port, FL_Port, M_Port, and EX_Port
Port types
The FC10-6 supports thiese port types:
E_Port and M_Port
The FR4-18i supports these port types:
FL_Port, F_Port, E_Ports, M_Port, VE_Port, EX_Port, and
VEX_Port
The FS8-18 supports these port types:
FL_Port, F_Port, E_Port, EX_Port, and M_Port
NOTE: Self-discovery is based on switch type (U_Port)
with an optional port type control.
See the Fabric OS Administrator's Guide for details on any
limitations of port type based on configuration.
FX8-24, FX8-24E support E_Port, EX_Port, and F_Port on
FC; and VE_Port on GbE
