Threshold 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 threshold trigger test for the trigger. When the trigger conditions are met, the agent sent an mteTriggerFired notification to the NMS.

1. Configure the device:

   # Add the user named 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 agent 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
   [Sysname] snmp-agent trap enable
   

2. Set the Event MIB minimum sampling interval to 50 seconds and set the maximum number to 10 for object instances that can be concurrently sampled.

   <Sysname> system-view
   [Sysname] snmp mib event sample minimum 50
   [Sysname] snmp mib event sample instance maximum 10
   

3. 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 Event MIB minimum sampling interval.

   [Sysname-trigger-owner1-triggerA] frequency 60
   

   # Specify the monitored object.

   [Sysname-trigger-owner1-triggerA] oid 1.3.6.1.4.1.25506.2.6.1.1.1.1.7.11
   

   # Enable the threshold trigger test. Specify the rising threshold, falling threshold, delta rising threshold, and delta falling threshold for the test.

   [Sysname-trigger-owner1-triggerA] test threshold
   [Sysname-trigger-owner1-triggerA-threshold] rising value 3
   [Sysname-trigger-owner1-triggerA-threshold] falling value 1
   [Sysname-trigger-owner1-triggerA-threshold] delta rising value 80
   [Sysname-trigger-owner1-triggerA-threshold] delta falling value 10
   [Sysname-trigger-owner1-triggerA-threshold] quit
   

   # Enable the trigger.

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

# Display Event MIB configuration and statistics.

[Sysname] display snmp mib event summary

# When the rising threshold of the monitored object 1.3.6.1.4.1.25506.2.6.1.1.1.1.7.11 is greater than 80, the NMS receives an mteTriggerFired notification.
