To continue creating a port mirroring session, select sources and traffic direction for the new port mirroring session.

You can create a port mirroring session without setting the source and destinations. When a source and destination are not set, a port mirroring session is created without the mirroring path. This allows you to create a port mirroring session with the correct properties set. Once the properties are set, you can edit the port mirroring session to add the source and destination information.
