PRB: SnmpMgrStrToOid Assumes Oid Is in Mgmt Subtree

The information in this article applies to:

Microsoft Win32 Software Development Kit (SDK) for Windows NT versions 3.1 and 3.5

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.
