We use Mitel/Aastra SIP Handsets, they are SNMP enabled and have previously been displaying data. Since changing to VLANS we can now only view the data under IP Location view.
If I view a Switch Asset, and look at a port I know a device is connected too, all I see is a MAC address and an unclickable Networking Device Icon.
Does anybody have any idea how to rectify this?
EDIT: I should add that Lansweeper scanning detects that the port is using VLans, it just doesn't recognise the device attached.
