Hi Jörg,
The agent code provides the interface protocol between the external
SNMP managers and the MIB. The MIB defines a data base of managed
information relative to a device, software module, or any other
entity to be managed. A MIB implementation defines the rules or
procedures necessary to obtain or modify the entries (objects) in
the data base.
You need to use the SNMP agent already installed in Windows and
integrate the printer MIB into that code. The details of this
integration are very specific to the design of the agent.
The value of hrDeviceIndex for the printer MIB instance corresponding
to your plotter can be any value desired, as long as it is unique
(i.e. does not conflict with any of the existing assignments).
Hope this information helps.

yes, the HR MIB is supportet from the Windows SNMP Service about the
windows agent hostmib.dll. This agent/dll create the mib tree, for example:
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.1 = 1
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.2 = 2
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.3 = 3
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.4 = 4
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.5 = 5
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.6 = 6
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.7 = 7
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.8 = 8
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.9 = 9
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.10 = 10
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceType.1 = OID:
host.hrDevice.hrDeviceTypes.hrDevicePrinter
...

no there is no other printer MIB in the system (i think that can exist
only one!) we want to develop our own printer mib dll.
> and using the existing SNMP agent?
yes we want to use the existing SNMP HOSTMIB agent dll.

this ist exactly the problem! we need a unique hrDeviceIndex in the
Printer MIB. And this unique Index comming from the Host Mib, isn´t it?
i think we must install our "printer" IN A WAY(?) that the SNMP HOSTMIB
agent dll identify this as a printer. and create for us the unique
hrDeviceIndex. in our example case:
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceIndex.11 = 11
...
host.hrDevice.hrDeviceTable.hrDeviceEntry.hrDeviceType.11 = OID:
host.hrDevice.hrDeviceTypes.hrDevicePrinter
:-)
how can we do that the SNMP HOSTMIB agent dll work for us? :-)
i am very interested in your answer!
all the best
