With D-Link DGS-1510-52XMP, the Switch Port Mapper is not able to return MAC addresses of devices connected on access ports with VLAN other than 1 assigned. Their DGS-1210-52MP is working fine with SPM.
D-Link support provided me with this:
QuoteFor MIB Obj dot1dTpFdbTable(1.3.6.1.2.1.17.4.3):
There is no VLAN ID used as index, so use VLAN ID 1 as default setting, only can get MAC of VLAN ID 1.
For MIB Obj dot1qTpFdbTable(1.3.6.1.2.1.17.7.1.2.2):
It can get all VLAN ID's MACs
Please access MIB Obj dot1qTpFdbTable(1.3.6.1.2.1.17.7.1.2.2)

Could you please update SPM, so it can read MAC table correctly? Thank you.
