We have applied for a Private Enterprise Number to "reserve" a space in the SNMP MIB "tree" to store some monitoring values. We will, eventually, be assigned a number like:
iso.org.dod.internet.private.enterprise.XXX (1.3.6.1.4.1.XXX)
We haven't received our allotted PEN yet, but I was hoping to get my project started by simply taking a (temporary, only on my workstation) OID and writing a value to it using SNMP#Net . I have followed the set example which works fine (the sysLocation
, OID 1.3.6.1.2.1.1.6.0
, is set fine).
So, next I tried setting a "faked" OID ( 1.3.6.1.4.1.99999.1.0
, where 99999
would, eventually, become our allotted PEN). This, however, fails with ErrorStatus 17
, which, according to this source , should be "The variable cannot be written or created."
I have checked my SNMP Agent service and the private
community which I'm using is set to READ/CREATE
. I am using C# on Windows 7.
Is there something I need to do before I can set my desired value? Do I need to import some kind of "MIB definition" before windows allows me to set a value? What would I need to do in order to (for now test) set values? Maybe I need to "declare" or "register" my desired OID first with the SNMP agent?
You need to register the variable in the SNMP Agent provider service as part of a binding list, using the WinSNMP API .
Essentially you use SnmpCreateVbl
to bind an OID to a variable.
