Forcing an Interface Addition

You can force the port configuration to be overwritten by the SAN port channel. In this case, the interface is
added to a SAN port channel.
• If you use the default On mode to avoid inconsistent states across switches and to maintain consistency
• If you use the Active mode, then the port channel ports automatically recover from the addition.
When SAN port channels are created from within an interface, the force option cannot be used.
Note
After the members are forcefully added, regardless of the mode (Active and On) used, the ports at either end
are gracefully brought down, indicating that no frames are lost when the interface is going down.
To force the addition of a port to a SAN port channel, perform this task:
