HKLM\SYSTEM\CurrentControlSet\Services\SNMP\
The SNMP subkey stores configuration data for the SNMP service.
The SNMP service implements Simple Network Management Protocol standards for TCP/IP and IPX networks. This service enables you to manage and monitor servers, workstations, routers, and hubs remotely from a centrally-located computer.
The SNMP\Parameters subkey contains subkeys that function like traditional registry entries. These subkeys store lists of items identified to the SNMP service. Each item in the list is represented by a numbered entry. The name of the item is the value of the entry.
