Boolean trigger test configuration example

As shown in Figure 54, the device acts as the agent. The NMS uses SNMPv3 to monitor and manage the device. Configure a trigger and configure a Boolean trigger test for the trigger. When the trigger condition is met, the device sends an mteTriggerFired notification to the NMS.

1. Configure the device:

   # Add the user owner1 to the SNMPv3 group g3. Assign g3 the right to access the MIB view a.

   <Sysname> system-view
   [Sysname] snmp-agent usm-user v3 owner1 g3
   [Sysname] snmp-agent group v3 g3 read-view a write-view a notify-view a
   [Sysname] snmp-agent mib-view included a iso
   

   # Configure the device to use the username owner1 to send SNMPv3 notifications to the NMS at 192.168.1.26.

   [Sysname] snmp-agent target-host trap address udp-domain 192.168.1.26 params securityname owner1 v3
   

   # Enable SNMP notifications for Event MIB.

   [Sysname] snmp-agent trap enable event-mib
   

2. Set the Event MIB minimum sampling interval to 50 seconds and set the maximum number to 100 for object instances that can be concurrently sampled.

   [Sysname] snmp mib event sample minimum 50
   [Sysname] snmp mib event sample instance maximum 100
   

3. Configure the Event MIB object lists. When a notification action is triggered, the system adds the objects in the specified object list to the notification.

   [Sysname] snmp mib event object list owner owner1 name objectA 1 oid 1.3.6.1.4.1.25506.2.6.1.1.1.1.6.11
   [Sysname] snmp mib event object list owner owner1 name objectB 1 oid 1.3.6.1.4.1.25506.2.6.1.1.1.1.7.11
   [Sysname] snmp mib event object list owner owner1 name objectC 1 oid 1.3.6.1.4.1.25506.2.6.1.1.1.1.8.11
   

4. Configure an event:

   # Create an event. Specify its owner as owner1 and its name as EventA.

   [Sysname] snmp mib event owner owner1 name EventA
   

   # Specify the notification action for the event.

   [Sysname-event-owner1-EventA] action notification
   

   # Specify the notification object hh3cEntityExtMemUsageThresholdNotification by its OID 1.3.6.1.4.1.25506.2.6.2.0.5 for the notification.

   [Sysname-event-owner1-EventA-notification] oid 1.3.6.1.4.1.25506.2.6.2.0.5 
   

   # Specify the object list to be added to the notification when the notification action is triggered

   [Sysname-event-owner1-EventA-notification] object list owner owner1 name objectC
   [Sysname-event-owner1-EventA-notification] quit
   

   # Enable the event.

   [Sysname-event-owner1-EventA] event enable
   [Sysname-event-owner1-EventA] quit
   

5. Configure a trigger:

   # Create a trigger. Specify its owner as owner1 and its name as triggerA.

   [Sysname] snmp mib event trigger owner owner1 name triggerA
   

   # Set the sampling interval to 60 seconds. Make sure the interval is greater than or equal to the global minimum sampling interval.

   [Sysname-trigger-owner1-triggerA] frequency 60
   

   # Specify the monitored object by its OID.

   [Sysname-trigger-owner1-triggerA] oid 1.3.6.1.4.1.25506.2.6.1.1.1.1.9.11
   

   # Specify the object list to be added to the notification when the notification action is triggered.

   [Sysname-trigger-owner1-triggerA] object list owner owner1 name objectA
   

   # Enable the Boolean trigger test. Specify the comparison type, reference value, event, and object list for the test.

   [Sysname-trigger-owner1-triggerA] test existence
   [Sysname-trigger-owner1-triggerA-existence] quit
   [Sysname-trigger-owner1-triggerA-boolean] comparison greater
   [Sysname-trigger-owner1-triggerA-boolean] value 10
   [Sysname-trigger-owner1-triggerA-boolean] event owner owner1 name EventA
   [Sysname-trigger-owner1-triggerA-boolean] object list owner owner1 name objectB
   [Sysname-trigger-owner1-triggerA-boolean] quit
   

   # Enable the trigger.

   [Sysname-trigger-owner1-triggerA] trigger enable
   [Sysname-trigger-owner1-triggerA] quit
