Swapping Ports

If there are no duplicate port numbers on the switch, you can swap physical Fibre Channel ports, except
the port numbers, by following these steps:
Issue the ficon swap portnumber old-port-number new-port-number command in EXEC mode.
Step 1
Note
The specified ports are operationally shut down.
Physically swap the front panel port cables between the two ports.
Step 2
Issue the no shutdown command on each port to enable traffic flow.
Step 3
Note
If there are duplicate port numbers on the switch, you can swap physical Fibre Channel ports, including
the port numbers, by following these steps:
Issue the ficon swap interface old-interface new-interface command in EXEC mode.
Step 1
The specified interfaces are operationally shut down.
Physically swap the front panel port cables between the two ports.
Step 2

Port swapping is not supported for logical ports (PortChannels, FCIP links). Neither the
old-port-number nor the new-port-number can be a logical port.
Port swapping is not supported between physical ports that are part of a PortChannel. Neither the
old-port-number nor the new-port-number can be a physical port that is part of a PortChannel.
Before performing a port swap, the Cisco NX-OS software performs a compatibility check. If the
two ports have incompatible configurations, the port swap is rejected with an appropriate reason
code. For example, if a port with BB_credits as 25 is being swapped with an OSM port for which a
maximum of 12 BB_credits is allowed (not a configurable parameter), the port swapping operation
is rejected.
Before performing a port swap, the Cisco NX-OS software performs a compatibility check to verify
the extended BB_credits configuration.
If ports have default values (for some incompatible parameters), then a port swap operation is
allowed and the ports retain their default values.
Port tracking information is not included in port swapping. This information must be configured
separately (see Chapter 57, "Configuring Port
13-1).
The ficon swap portnumber command might fail if more than one interface on the MDS switch
has the same port number as the old-port-number or new-port-number specified in the command.
If you specify the ficon swap portnumber old-port-number new-port-number after swap
noshut command, the ports are automatically initialized.
