To ensure that ports that are part of ISLs do not get changed to port mode F, configure the ports in port

mode E, rather than in Auto mode.
When the command is executed from the command line, switch operation remains graceful. No ports are
Note
flapped.
To set the administrative mode of Fibre Channel ports to mode F in the CLI, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# system default
switchport mode F
switch(config)# no system default
switchport mode F
For detailed information about the switch setup utility see the Cisco MDS 9000 Family NX-OS

Fundamentals Configuration Guide.

Configuring Port Speeds

By default, the port administrative speed for an interface is automatically calculated by the switch.
Changing the port administrative speed is a disruptive operation.
Caution
To configure the port speed of the interface, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc 1/1
Step 3
switch(config-if)# switchport speed 1000
switch(config-if)# no switchport speed

Purpose
Enters configuration mode.
Sets the administrative mode of Fibre Channel ports to
mode F (if applicable).
Sets the administrative mode of Fibre Channel ports to
the default (unless user configured).
Purpose
Enters configuration mode.
Selects the mgmt0 interface and enters interface
configuration mode.
Configures the port speed of the interface to 1000
Mbps.
The number indicates the speed in megabits per
second (Mbps). You can set the speed to 1000 (for
1-Gbps interfaces), 2000 (for 2-Gbps interfaces),
4000 (for 4-Gbps interfaces), 8000 (for 8-Gbps
interfaces), or auto (default).
Reverts the factory default (auto) administrative
speed of the interface.
