To create and run a MPLS P2MP LSP ping OAM diagnostic test from the STM

Steps
 
1 

Choose Tools→Service Test Manager (STM) from the NFM-P main menu. The Service Test Manager form opens.

2 

Click Create and choose MPLS→P2MP LSP Ping. The P2MP LSP Ping (Create) form opens.

3 

Configure the required parameters.

4 

Perform one of the following:

  1. If you selected P2MP RSVP as your Target Type:

    1. Select a P2MP dynamic LSP in the P2MP Dynamic LSP panel.

    2. Select a P2MP Instance in the P2MP Instance panel.

    3. Configure the Select All S2L Paths parameter.

      If you enabled the parameter, go to Step 5 .

    4. Click on the S2L Paths tab.

    5. Click Add and select one or more S2L paths (up to a maximum of five).

  2. If you selected P2MP mLDP as your Target Type:

    Note: For the test to execute successfully, ensure the following:

    • The LDP protocol must be enabled on all NEs between the source and destination, including any intermediate NEs.

    • LDP interfaces must be in place between the source and destination NEs.

    • LDP interfaces must be up, and the Multicast Forwarding parameter must be enabled on each interface. This also applies to all intermediate NEs. See To configure an LDP interface for information about configuring LDP interfaces.

    Perform the following:

    1. Configure the required parameters.

    2. Select the P2MP ID you want to test in the P2MP LDP panel.

    3. Click on the LDP Leaf Addresses tab.

    4. Click Add and select up to five leaf NEs.

  3. If you selected P2MP mLDP-SSM as your Target Type:

    Note: For the test to execute successfully, ensure the following:

    • The LDP protocol must be enabled on all NEs between the source and destination, including any intermediate NEs.

    • LDP interfaces must be in place between the source and destination NEs.

    • LDP interfaces must be up, and the Multicast Forwarding parameter must be enabled on each interface. This also applies to all intermediate NEs. See To configure an LDP interface for information about configuring LDP interfaces.

    Perform the following:

    1. Select the System ID (Loopback IP Address) in the P2MP LDP SSM panel.

    2. Configure the Router Instance type (either a base router or a VPRN service). If you select Service, then you must also select the required VPRN Instance.

    3. Select the Source Address. The Group Address field will be automatically populated, depending on your choice of Source Address. However, you can also manually enter a multicast address in the Group Address field, as required.

    4. If you selected Service as the Router Instance type, then go to Step 5 .

    5. Select a Sender Address.

    6. Click on the LDP Leaf Addresses tab.

    7. Click Add and select up to five leaf NEs.

  4. If you selected P2MP Policy as your Target Type, perform the following:

    1. Select a System ID (Loopback IP Address).

    2. Select the Root Address, Root Tree Id, and Root Tree Instance Id.

    3. Click on the Leaf Addresses tab.

    4. Click Add and select up to five leaf addresses.

5 

Click on the Test Parameters tab and configure the required parameters.

The Time To Live parameter is only displayed if you selected P2MP RSVP as your Target Type.

6 

Click on the Results Configuration tab and configure the required parameters.

7 

As required, click on the NM Thresholds tab to configure threshold-crossing alarms. See To configure threshold-crossing alarms or NM threshold-crossing alarms for an OAM diagnostic test or STM test policy for more information.

8 

Click OK to save the changes. The Service Test Manager form opens.

9 

Choose the created test from the list of OAM diagnostics and click Properties.

The P2MP LSP Ping (Edit) form opens.

10 

Click Execute to start the P2MP LSP ping. A deployed test is created and run. Open the deployed test to view its current state. When the test is complete, the deployed test is removed, and you can view the results.

Note: When this test is performed on an existing Point-to-Multipoint LSP, up to five S2L paths (for a P2MP RSVP target type) or five LDP leaf addresses (for a P2MP mLDP or P2MP mLDP-SSM target type) can be selected. If none are selected, all available paths or addresses up to the limit of five will be pinged.

11 

Click on the Results tab in the P2MP LSP Ping (Edit) form.

The Results tab will show an entry for each S2L path (RSVP) or leaf address (mLDP or mLDP-SSM) tested.

12 

Select the test from the list and click on Properties. The P2MP LSP Ping Packet Result form opens.

The General tab displays the test parameters you configured, along with time the test was executed, its status, and the following test information:

  • Number of Packets Sent

  • Packet Timeouts

  • Number of Responses Received

  • Number of Packets Lost

  • Loss Percentage

  • Last Good Packet Time

Note: The test results depend on the type of test you run. See To view and compare OAM diagnostic test results on the STM for more information.

13 

Click on the Details tab.

14 

View the test results for the:

  • Round Trip Time

  • Outbound One Way Time

  • Inbound One Way Time

15 

Click on the Response Packets tab.

16 

Select a response packet from the list and click on Properties. The P2MP LSP Ping Packet Result form opens.

Note: The test results depend on the type of test you run. See To view and compare OAM diagnostic test results on the STM for more information.

17 

View details on the response packet, including:

  • Status

  • Round-Trip Time

  • Response sequence

18 

Repeat Step 12 to Step 17 for all tested S2L paths (RSVP) or leaf addresses (mLDP).
