Map display - link mastering and snmp v3

Hello,

I am trying to set up snmp utilisation on my Dude 3.6 map on a link connected to an snmp v3 node. The link mastering setup cannot retrieve the interface info - there is only one thing on the available interfaces, and it flips between (unknown) and (some_large_number) e.g. (4927864528).

snmpwalk and snmpget however works fine on the device.

Same thing happens in the 4.0beta version.

Anyone come across this and got around it ? I think same thing used to happen if you tried to access Cisco PIX with snmp v2.

Regards,
IShall.
