Trap Config Manager

Trap Configuration Reference

The trap configuration comprises the user defined trap profiles, severity definitions, trap speak dictionary, and trap filter definitions. All these can be scripted using the "UnbrowseSNMP.TrapConfiguration" object. These objects allows you to manage hundreds of carefully defined trap profiles and severity levels.

TrapConfigManager (top level object)

Allows high level access to maintain user defined trap profiles, severity levels, trap filters, and trap speak dictionary.

Creating the top level object

VBScript

Set TrapConfig = CreateObject("UnbrowseSNMP.TrapConfigManager")

Ruby 

myTrapConfigObject = WIN32OLE.New("UnbrowseSNMP.TrapConfigManager")

Properties and Methods

Name	Parameters	Access	Description
Profiles	Collection of TrapProfile objects - Return	Read	All the trap profiles defined in Unbrowse SNMP. Eg. For Each Prof In TrapMgr.Profiles - - - Next
Groups	Collection of TrapGroup objects	Read	All the trap groups defined in Unbrowse SNMP.
Filters	Collection of TrapFilter objects	Read	All the trap filters defined in Unbrowse SNMP.
SpeakDictionary	Trap Speak Dictionary object	Read	The Trap Speak Dictionary is an advanced feature of Unbrowse SNMP. It allows you to convert text like "Fast Ethernet 0" into speech such as "NJ T1 4 circuit".
Load		NA	Load the Trap Configuration. This method must be called before any accessing other information.
Open		NA	Same as load
Save		NA	Save the changes made to the trap configuration.
NewTrapProfile	String - OID TrapProfile object- Return value	NA	Create a new trap profile object. Each trap profile is associated with a single OID corresponding to the trap.
RemoveTrapProfile	String - Trap OID	NA	Removes the trap profile for the specified OID. No harm is done if a trap profile with the OID does not exist. See Also: IsTrapProfilePresent method to check if a particular trap OID has a profile associated with it.
NewTrapFilter	Trap Filter object - return value	NA	Creates a new trap filter object.
RemoveTrapFilter	String - name	NA	Remove the trap filter object with the given name.
NewTrapGroup	Trap Group object - return value	NA	Creates a new trap group.
RemoveTrapGroup	Trap Group object	NA	Removes the specified trap group object.
IsTrapProfilePresent	String - Trap OID Bool - Return	NA	Return "True" if a trap profile exists for the specified Trap OID.
AddVarbindEnum	String - Varbind OID Numeric - Enum Number String - Enum Name	NA	This is an advanced feature of the Unbrowse SNMP trap receiver. Allows you to assign user friendly strings to varbind values.
LookupVarbindEnum	String - Varbind OID Numeric - Enum Number String - Return value	NA	Converts a varbind enum number to a user friendly name.

TrapProfile

Trap Profiles allow you to control how a particular SNMP trap is handled by the trap receiver.
You can:

Assign a severity level to a trap
Control how a trap is formatted and displayed
Assign a trap speak message (for the text to speech engine)
Assign a correlation expression (when you get a trap, you can perform a SNMP GET to obtain more information automatically)

Events

None

Properties and Methods

Name	Parameters	Access	Description
OID	String		The trap OID of the trap. A trap profile is associated with a specific trap object.
Severity	TrapSeverity	Read Write	The default trap severity level assigned to this trap
DisplayFormat	String	Read Write	Trap Display format string. Controls how a trap is displayed. See online help for all available formatting expressions.
SpeakFormat	String	Read Write	For the TrapSpeak feature. Controls what phrases are spoken when a particular trap is received. See online help for available options.
TrapGroups	Collection of TrapGroup objects	Read	Collection of trap group objects
AddToTrapGroup	Trap Group object		Add this trap to a trap group.
RemoveFromTrapGroup	Trap Group object		Remove this trap from the specified trap group
	String	Read	The Trap OID
HasSeverityExpression	Bool	Read	Does this trap profile have a severity expression ? A severity expression is used to assign a severity level to a trap based on the value of certain varbinds..
TrapSeverityExpressionCount	Numeric	Read	The number of trap severity expressions.
GetTrapSeverityExpressionByIndex	Numeric - Index of trap sev expression Numeric Ref - Varbind Index String Ref - Operator string Numeric - Varbind value Trap Severity -	NA	Get the trap severity expression by index.
SeverityControlVariable	Numeric	Read Write	Unbrowse SNMP can assign a custom severity to a trap based on many values of a single varbind. This varbind is called a control variable. This property returns the control variable from among the varbinds.
AddTrapSeverityExpression	String - Operator Numeric - Value of varbind Trap Severity - Severity i	NA	Adds a trap severity expression.
DefaultCustomSeverity	Trap Severity	NA	If none of the trap severity expressions match. This is the severity attached to the trap.
CorrelationExpression	String	Read	Trap correlation is an advanced feature of Unbrowse SNMP. The correlation expression is used to retrieve additonal information from SNMP agets via a GET, in response to certain traps.

TrapFilter

TrapSpeakDictionary

Advanced feature of Unbrowse SNMP. The Trap Speak feature allows you to put Unbrowse SNMP in a corner and speak out traps information as they are received. This allows you to monitor traps in a hands off manner in a lab environment. The Trap Dictionary allows you to convert specific text strings to speech friendly phrases. For example : You can convert "10.17.20.4-FastEthernet/0" to "East Wing Link to second floor"
