PRB: SnmpMgrStrToOid Assumes Oid Is in Mgmt Subtree (129063)
The information in this article applies to:
- Microsoft Win32 Software Development Kit (SDK) for Windows NT
This article was previously published under Q129063 SYMPTOMS
When using the SNMP Manager API SnmpMgrStrToOid() and passing it a valid
Oid, the application is unable to get the requested variables.
CAUSE
The SNMP Manager API SnmpMgrStrToOid assumes that the Oid that is supplied
to it is under the internet MIB of the mgmt subtree (1.3.6.1.2.1.x).
RESOLUTION
To get variables that are not under the mgmt subtree, the Oid must be
preceeded by a period (.). For example, say an application is trying to get
the system group and the Oid passed to SnmpMgrStrToOid is this:
1.3.6.1.2.1.1
Then the application will try to get the following, which does not exist:
iso.org.dod.internet.mgmt.1.1.3.6.1.2.1.1
The correct way to get the system group is to pass this:
.1.3.6.1.2.1.1
STATUS
This behavior is by design.
