Using the J-Web Ping MPLS Tool

Before using the ping MPLS feature, make sure that the receiving interface on the VPN or LSP remote endpoint has MPLS enabled, and that the loopback interface on the outbound node is configured as 127.0.0.1. The source address for MPLS probes must be a valid address on the J Series device.

To use the ping MPLS tool:

  1. Select Troubleshoot > Ping MPLS from the task bar.

    After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

  2. Click the expand icon next to the ping MPLS option you want to use (see Figure 22).
  3. Enter information into the Ping MPLS page, as described in Table 69.
  4. Click Start.

    Table 69 summarizes the output fields of the display.

  5. To stop the ping operation before it is complete, click OK.
