Hello Aarón, Thank you for your reply. OK, now I got the new linecard in my inventory. But there is still the old one in the system. I think I need a command, to delete the linecard(ports) Cheers Mathias From: Aarón Fuentes Öhnell <cctired@ull.edu.es> Sent: Freitag, 2.

Is it possible to refresh the inventory of that device so that I can see the new ports? Cheers Mathias
