MIB Browser Reference

The "MIB Browser" scripting interface provides access to compiled MIB objects, and their definitions. You can also compile MIBs from the command line using the methods of this interface.

MIBBrowser (top level object)

The top level object used to navigate SNMP MIB definitions and to compile raw MIB files in ASN.1 format into Unbrowse SNMP. When you compile SNMP MIBs into Unbrowse SNMP, they are converted into a compact fast loading format called the *.VOSMI. This allows Unbrowse SNMP to load and search MIB modules rapidly.

Creating the top level object

VBScript

Set Mibbrowser = CreateObject("UnbrowseSNMP.MIBBrowser")

Ruby

browser = WIN32OLE.New("UnbrowseSNMP.MIBBrowser")

Properties and Methods

Name	Parameters	Access	Description
CompileASN	String - full path to the MIB file MIBModule Object - Return value	NA	Compiles the specified MIB file and return a MIBModule object containing all the information about the objects in the MIB
SaveAs	String - file name	NA	Save the compiled file into this file name. Usually this is the file "modulename".vosmi
GetErrorResult	Numeric - Result	NA	0 - if the MIB compilation was a success 1 - if failure due to errors 2 - if warnings present, but success
GetErrorSummary	Numeric - Return number of errors Numeric - Return number of warnings	NA	Returns the number of errors and warnings that resulted from a CompileASN method
SetPath	String - path	NA	Add a semicolon separated list of paths to search from IMPORTED MIBs while compiling
GetModule	MIBModule object - return	NA	Returns the MIB module object
GetModuleIndex	Collection of Nodes	NA	All the SNMP objects defined in this module
ErrorText	String	Read	Error text that resulted from a CompileASN or Compile operation
ErrorMessageSeverity	Numeric	Read Write	A number from 0 to 9. This controls the granularity of the error messages
Strictness	Numeric	Read Write	A number from 0 to 9. This controls how strict the MIB compiler is
AddPath	String - path to add	NA	Adds a path to the list of paths to search for IMPORTed MIB definition files
EnableDeepSearch	Bool	Read	Deep Searching is an advanced feature of Unbrowse SNMP. When set to true: Unbrowse SNMP does not assume any naming convention for MIB files. So, as while searching for IMPORTed modules, it scans the the module definition ASN.1 block looking for a match.
Open	String - path of compiled file MIB Module object - Return value	NA	Open a pre-compiled MIB Module stored in the given VOSMI file.

MIBModule

Corresponds to a single SNMP MIB module.

Events

None

Properties and Methods

Name	Parameters	Access	Description
Name	String	Read Write	The name of the MIB module
DatabasePath	String	Read	The full path of the compiled MIB module file. The compiled MIB module files are typically stored in the Unbrowse MIB repository with the extension *.VOSMI
Path	String	Read Write	The full path of the plain MIB file. Plain MIB files are the normal ASN.1 MIB definition files.
Organization	String	Read Write	Organization name
ContactInfo	String	Read Write	Contact information
Description	String	Read Write	Description section from the MIB definition
Reference	String	Read Write	Reference
FindNodeByName	String - Node name MIBNode object - Return value	NA	This method searches the MIB module for a given node by name (eg, sysUpTime).
FindBestOIDMatch	String - OID MIB Node object - Return value	NA	Search the MIB module for a node with an OID with the longest match of the input OID. If an exact match is found, that node is returned.
ChildNodes	Collection of MIBNode objects	NA	A collection of all the node defined in this MIB module

MIBNode

Corresponds to a single node defined in the MIB module

Events

None

Properties and Methods

Name	Parameters	Access	Description
Name	String	Read Write	The name of the node. Example : "sysUpTime"
OID	String	Read Write	The OID of the node.
Description	String	Read Write	The description of the node as specified in the MIB definition.
NodeType	Numeric - see NodeTypeEnum	Read	The node type. See the NodeTypeEnum for a list of valid NodeTypes.
OIDName	String	Read	The full name of the node Example: ".iso.dod.internet.mgmt"
ShortOID	Numeric	Read Write	The last digit of the OID
FindNodeByName	String - node name MIBNode object - return value	NA	Search all the children of this node for a given name
Type	MIBNodeType object - return value	Read	You can use the MIBNodeType object for more information about the type of the node.
Children	Collection of MIBNode objects	Read	All the immediate children of this node

MIBNodeType

An SNMP Type object.

Events

None

Properties and Methods

Name	Parameters	Access	Description
Name	String	Read Write	Name of the type
Description	String	Read Write	Description
FindNameForNumber	Numeric - a numeric enum value String - the name for the enum	NA	This method is used to lookup enumerated name value pairs in the type definition. Example : Set MyType = Mod.FindNodeByName("ifType").Type TypeStr = MyType.FindNameForNumber (6) Will return "Ethernet/CSMA-CD"
BaseType	Numeric - see the BaseType enumeration	NA	The base type. See the basetype enum for a list of all valid basetypes.
