SNMP Passive Monitor instance

How to get here

Enter the appropriate information into the following fields.

• Name. The name of the monitor as it appears in the Passive Monitor Library.
• Description. The description of the monitor as it appears in the Passive Monitor Library.
• Enterprise/OID. Use the browse button to select the desired object identifier (OID) from the Enterprise section of the MIB. This is the SNMP enterprise identifier in the trap, which is used for unique identification of traps for a particular application. If you specify the OID in this field, then an incoming trap will match this rule only if the trap enterprise field begins with the OID that you have specified. If you are unsure of the OID to use, or don't care to be specific, you can leave this field blank and it will be ignored.

  Note: This option is only available if Generic Type is set to 6-EnterpriseSpecific.

• Generic Type (Major). Each trap has a generic type number. This number is part of the rule that determines the matching criteria for an incoming trap.  

  Note: The definitions of 0 through 6 are not WhatsUp Gold definitions, but come from the SNMP specifications.

• Specific Type (Minor).  This can have an integer value from 0 to 4294967296. To use this option, Generic Type must be always enterprise specific. If you want to ignore this field, select "Any".

Click the Add button to view the Expression Editor where you can create an expression, test it, and compare it against potential payloads you can receive. After creating the expression, click OK to insert that string into the Match on box.

Note: If you have multiple payload "match on" expressions, they are linked by "OR" logic - not "AND" logic. If you have two expressions, one set to "AB" and the other to "BA", it will match against a trap containing any of the following: "AB" or "BA" or "ABBA".

Click OK to add the monitor to the Passive Monitor Library.
