Configuring Interface Modes
To configure the interface mode, follow these steps:
switch# config t
switch(config)# interface fc1/1
switch(config-if)# switchport mode F
switch(config-if)# switchport mode auto
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:
This command does not affect the configuration of the following ports:

All ports that are down and that are not out-of-servicel.
All F ports that are up, whose operational mode is F, and whose administrative mode is not F.
All user-configured ports, even if they are down.
All non-F ports that are up; however, if non-F ports are down, this command changes the
administrative mode of those ports.
