Switch inventory isn't updated

At http://nav.setic.ufsc.br/report/swport, I can view my interfaces with VLANs assignments. The problem is: the information for a given netbox isn't updated. All of the jobs are running fine for that netbox (green lights in jobs list). For example: I've a set of tagged VLANs in a trunk port on that switch that isn't reported by NAV. I'll sent to Morten DEBUG logs from ipdevpolld inventory job. -- Att. Bruno Galindro da Costa
