SNMP operation configuration example

As shown in Figure 14, configure an SNMP operation to test the time the NQA client uses to get a response from the SNMP agent.

1. Assign IP addresses to interfaces, as shown in Figure 14. (Details not shown.)

2. Configure static routes or a routing protocol to make sure the devices can reach each other. (Details not shown.)

3. Configure the SNMP agent (Device B):

   # Set the SNMP version to all.

   <DeviceB> system-view
   [DeviceB] snmp-agent sys-info version all
   

   # Set the read community to public.

   [DeviceB] snmp-agent community read public
   

   # Set the write community to private.

   [DeviceB] snmp-agent community write private
   

4. Configure Device A:

   # Create an SNMP operation.

   <DeviceA> system-view
   [DeviceA] nqa entry admin test1
   [DeviceA-nqa-admin-test1] type snmp 
   

   # Specify 10.2.2.2 as the destination IP address of the SNMP operation.

   [DeviceA-nqa-admin-test1-snmp] destination ip 10.2.2.2
   

   # Enable the saving of history records.

   [DeviceA-nqa-admin-test1-snmp] history-record enable
   [DeviceA-nqa-admin-test1-snmp] quit
   

   # Start the SNMP operation.

   [DeviceA] nqa schedule admin test1 start-time now lifetime forever
   

   # After the SNMP operation runs for a period of time, stop the operation.

   [DeviceA] undo nqa schedule admin test1
   

   # Display the most recent result of the SNMP operation.

   [DeviceA] display nqa result admin test1
   NQA entry (admin admin, tag test1) test results:
       Send operation times: 1              Receive response times: 1
       Min/Max/Average round trip time: 50/50/50
       Square-Sum of round trip time: 2500
       Last succeeded probe time: 2011-11-22 10:24:41.1
     Extended results:
       Packet loss ratio: 0%
       Failures due to timeout: 0
       Failures due to internal error: 0
       Failures due to other errors: 0
   

   # Display the history records of the SNMP operation.

   [DeviceA] display nqa history admin test1
   NQA entry (admin admin, tag test1) history records:
     Index      Response     Status           Time
     1          50           Succeeded        2011-11-22 10:24:41.1
   

   The output shows that it took Device A 50 milliseconds to receive a response from the SNMP agent.
