MG-SOFT Net Inspector — Reference Manual
Server Settings Dialog Box
When you create a trap-to-alarm rule from a received specific SNMP notification, the
Specific OID value is automatically set to match the SNMP notification specific OID.
Note: Specific OID value is the key condition that is checked first in received SNMP notification
message. Only if the specific OID value of a received notification matches the one specified in the
trap-to-alarm rule, the remaining conditions of the given rule (trap filter) are evaluated (compared
to notification attributes).
Edit (button)
Opens the Specific OID dialog box that lets you edit or select the notification’s
enterprise specific OID from the MIB tree.
Name
Displays the name of the specific OID as it resolves through loaded MIB modules. For
user-friendlier SNMP notification viewing and handling, you should load the private MIB
module(s) that define relevant enterprise specific SNMP notifications into Net Inspector.
New condition (toolbar)
The New condition toolbar lets you create conditions and add them to the trap filter oneby-one, while the central section of the dialog box (Conditions panel) displays existing
filter conditions and relations between them. The Conditions panel displays a trap filter in
form of a hierarchical tree, where individual conditions are connected with logical
operators (AND, OR).
