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 Services Router.

To use the ping MPLS tool:

  1. Select Diagnose>Ping MPLS from the task bar.
  2. Next to the ping MPLS option you want to use, click the expand icon (see Figure 136).
  3. Enter information into the Ping MPLS page, as described in Table 173.
  4. Click Start.

    Table 174 summarizes the output fields of the display.

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