Environment:Ubuntu 16.04.3 LTS + postgresql 10
Equipment: Datacom DM4008/DM4004
Mibs: IF-MIB, Datacom MIB (attached)
I use a LLD discovery rule to retrieve only up ports into host for monitoring (see rd_dmswitch_interfaces script).
The Dmswitch mib contain diagnostic informations for transceivers that support this feature (RX/TX power, VCC, etc) at .1.3.6.1.4.1.3709.3.5.201.1.28. The equipment generate information ONLY for transceivers that support DD (digital diagnostic) and I think that is the start of issue.
snmpwalk examples:

LLD rule works OK for all interfaces itens but all discovered items from Datacom mib (transceivers information) are gerenate as unsupported.
As an example, I attach interface "89" information retrieved from discovery rule. All seen to be OK but zabbix don't retrieve the information. On snmpwalk I can retrieve information without any problem.
