If you attempt to bring the port up by specifying the ficon swap portnumber old-port-number
new-port-number after swap noshut command, you must explicitly issue the no shutdown command
to resume traffic.
To swap physical Fibre Channel ports, follow these steps:
Issue the ficon swap portnumber old-port-number new-port-number command in EXEC mode.
Step 1
The specified ports are operationally shut down.
Step 2 Physically swap the front panel port cables between the two ports.
Issue the no shutdown command on each port to enable traffic flow.
Step 3

Port Swapping Guidelines

Be sure to follow these guidelines when using the FICON port swap feature:
•
•
•
•
•
•
Note The 32-port module guidelines also apply for port swapping configurations (see the
Configuration Guidelines" section on page
Cisco MDS 9000 Family Configuration Guide
24-26
If you specify the ficon swap portnumber old-port-number new-port-number after swap
noshut command, the ports are automatically initialized.
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 SAN-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 SAN-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 48, "Configuring Port Tracking").
11-8).
