Hello,

´switchport mode dynamic desirable´ means that the switchport actively tries to convert the link to a trunk link, when the other side is a trunk link. This in contrast with e.g. ´switchport mode dynamic auto´, which means that the link gets converted to a trunk link only when the other side requests it...

Regards,

Georg
