Once you swap ports, the switch automatically performs the following actions:

If you attempt to bring the port up, you must explicitly shut down the port to resume traffic.

If you swap a port in a module that has unlimited oversubscription ratios enabled with a port in a
module that has limited oversubscription ratios, then you may experience a degradation in
bandwidth.

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 65, "Configuring Port
