Configuring System Default Port Mode F
The system default switchport mode F command sets the administrative mode of all Fibre Channel
ports to mode F, while avoiding traffic disruption caused by the formation of unwanted Inter-Switch
Links (ISLs). This command is part of the setup utility that runs during bootup after a write erase or
reload. It can also be executed from the command line in configuration mode. This command changes
the configuration of the following ports to administrative mode F:

Command Line
Purpose
Enters configuration mode.
Selects a Fibre Channel interface and enters interface
configuration submode.
Configures the administrative mode of the port. You
can set the operational state to auto, E, F, FL, Fx, TL,
NP, or SD port mode.
Note Fx ports refers to an F port or an FL port (host
connection only), but not E ports.
Configures the interface mode to auto-negotiate an E,
F, FL, or TE port mode (not TL or SD port modes) of
operation.

configured.
You cannot configure Fibre Channel interfaces
