A delta table also exists within the trigger tables. This table stores information about any
delta values based on any Boolean and threshold triggers. The delta table stores a MIB
object that indicates whether any discontinuities occurred for any delta trigger (for
example, a router reset).
NOTE: When determining discontinuity, the MIB object must be a time-based
counter or number. When a polling interval expires and the event agent
(router) needs to perform a delta calculation, it first checks the discontinuity
MIB object for that trigger. If a discontinuity occurs, the agent does not perform
the test for that trigger until the next polling interval.

Objects Table

The objects table (mteObjectsTable) defines objects that you want to add to event
messages. In other words, you can create a list of user-specified objects and bind them
to a trigger event. This can provide a snapshot of other values on a router when the trigger
occurs. You can bind objects to a specific trigger, a type of test (for example, existence
or Boolean tests), or a type of event (for example, rising or falling events).
NOTE: This release does not support the objects table.

Event Table

The event table (mteEventTable) defines what action you want the device to take when
a trigger occurs. This action can be in the form of a notification, setting a specified MIB
object, or both. The results of these actions are controlled within two subordinate MIB
tables—notification and set.
Notifications (mteNotifications), or traps, define what the router sends when an event
occurs. These traps include the following:
When a Boolean or existence trigger occurs, the router sends an mteTriggerFired trap.
When a rising threshold trigger occurs, the router sends an mteTriggerRising trap.
When a falling threshold trigger occurs, the router sends an mteTriggerFalling trap.
If a trigger fails to complete a test for any reason, the router sends a global
mteTriggerFailure trap.
If an event fails to set, the router sends an mteEventSetFailure trap.
Sets define certain modifications to other MIB objects based on a particular event.
To configure the SNMP server event manager:
Access the SNMP server management event application.
