Usage Guidelines

Usage Scenario

A physical interface cannot be created. You can run the interface command to enter the interface view directly.

A logical interface can be created. You can run the interface command to create a logical interface and enter the view of the logical interface.

Precautions

After a logical interface is deleted using the undo interface command, all the configurations on the interface are automatically deleted. These configurations cannot be restored even if you create an interface same as the one deleted.
