Issue:

After compiling and adding a vendor mib into Spectrum MIB Tools, the mib is placed in the Unknown folder and not in the expected vendor folder. For example, the IB-SMI-MIB as seen below:

Cause:

During import of any mib in MIB Tools, Spectrum finds the common OID between the MODULE-IDENTITY and the Root Node of the mib. If the common OID has vendor, it places the MIB in the vendor folder.

The Root Node of the IB-SMI-MIB.mib is "enterprises" (1.3.6.1.4.1), children of the root node are "infoblox (1.3.6.1.4.1.7779), ibDNSServ ( 1.3.6.1.4.1.32) and ibDHCPServ (1.3.6.1.4.1.9999)". The common OID in between all children of the root node is 1.3.6.1.4.1. As vendor is empty in the common OID, Spectrum placed the IB-SMI-MIB.mib in "Unknown" folder. 

 

As multiple vendors defined in the IB-SMI-MIB.mib, the common OID is "1.3.6.1.4.1

1.3.6.1.4.1.7779 ( 7779 - infoblox ) 

1.3.6.1.4.1.32 ( 32 - Santa Cruz Operation ) 

1.3.6.1.4.1.9999 ( 9999 - Zerna, Koepper & Partner )

Resolution:
None as this needs to be addressed by the vendor of the mib.
