D-Link DGS switches (some) - IPv6 addresses discovery

I see that there is a new definition feature:
'ip-address'

Great!

I add IPv6 addresses discovery for
DGS-3120-24SC (tested, works)
DGS3627G (tested, works)
DGS-3420-26SC (not fully tested, I haven't accces to switch with IPv6 address configured)
DGS-3420-28SC (not fully tested, I haven't accces to switch with IPv6 address configured)

I use entity_match in definition, but in used table there is an oid with ifIndex.
