Example for Configuring an NQA LSP Ping Test to Monitor MPLS Network Connectivity

This section provides an example for configuring an NQA LSP ping test to monitor MPLS network connectivity.

Networking Requirements

On the MPLS network shown in Figure 1, Device A and Device C are PEs. An NQA LSP ping test can be configured to periodically monitor the connectivity between these two PEs.

Figure 1 Networking diagram for an NQA LSP ping test to monitor MPLS network connectivity

Interfaces 1 through 2 in this example are GE0/1/0, and GE0/1/8, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Create an LSP ping test instance on Device A.
Start the test instance.

Data Preparation

To complete the configuration, you need the IP addresses of Device A and Device C.

Procedure

Create an LSP ping test instance.

<DeviceA> system-view
[~DeviceA] nqa test-instance admin lspping
[*DeviceA-nqa-admin-lspping] test-type lspping
[*DeviceA-nqa-admin-lspping] lsp-type ipv4
[*DeviceA-nqa-admin-lspping] destination-address ipv4 3.3.3.9 lsp-masklen 32

Start the test instance.

[*DeviceA-nqa-admin-lspping] start now
[*DeviceA-nqa-admin-lspping] commit

Verify the test result.

Run the display nqa results test-instance admin lspping command on Device A. The command output shows that the ping is successful.

[~DeviceA-nqa-admin-lspping] display nqa results test-instance admin lspping
 NQA entry(admin, lspping) :testFlag is inactive ,testtype is  lspping

   Sum/Square-Sum  Completion Time: 3/3
   Last Good Probe Time: 2007-1-30 15:32:56.1
   Lost packet ratio:0%

Configure the test instance to start at 10:00 o'clock every day.

[*DeviceA-nqa-admin-lspping] stop
[*DeviceA-nqa-admin-lspping] start daily 10:00:00 to 10:30:00  
[*DeviceA-nqa-admin-lspping] commit
