Configuring On-Demand Loss and Delay Measurement


You can configure an on-demand loss and delay measurement for point-to-point ultimate hop popping (UHP) label-switched paths (LSPs) in MPLS networks to monitor network performance. The monitor mpls loss rsvp, monitor mpls delay rsvp, and monitor mpls loss-delay rsvp CLI commands provide an on-demand summary of performance metrics for direct mode packet loss, two-way packet delay, and related metrics, such as inter-packet delay variation and channel throughput measurement.

This functionality provides real-time visibility into network performance, thereby facilitating network performance planning, troubleshooting, and evaluation.

Before you begin:

  1. Configure the device interfaces.

  2. Configure the device router ID.

  3. Configure the following protocols:

    • RSVP

    • OSPF

      Enable traffic engineering capabilities.

    • MPLS

To configure the PE device:

  1. Enable the chassis with tunnel services and enhanced IP network services configuration.
  2. Configure an associated bidirectional LSP to the remote router.
  3. Create traffic classes for maintaining data traffic statistics per traffic class.

    This enables traffic class scoped loss measurement.
