Voice operation configuration example

As shown in Figure 18, configure a voice operation to test jitters, delay, MOS, and ICPIF between Device A and Device B.

1. Assign IP addresses to interfaces, as shown in Figure 18. (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 Device B:

   # Enable the NQA server.

   <DeviceB> system-view
   [DeviceB] nqa server enable
   

   # Configure a listening service to listen on IP address 10.2.2.2 and UDP port 9000.

   [DeviceB] nqa server udp-echo 10.2.2.2 9000
   

4. Configure Device A:

   # Create a voice operation.

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

   # Specify 10.2.2.2 as the destination IP address.

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

   # Set the destination port number to 9000.

   [DeviceA-nqa-admin-test1-voice] destination port 9000
   [DeviceA-nqa-admin-test1-voice] quit
   

   # Start the voice operation.

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

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

   [DeviceA] undo nqa schedule admin test1
   

   # Display the most recent result of the voice operation.

   [DeviceA] display nqa result admin test1
