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:
Configure the device interfaces.
Configure the device router ID.
Configure the following protocols:
Enable traffic engineering capabilities.
To configure the PE device:
- Enable the chassis with tunnel services and enhanced IP

- Configure an associated bidirectional LSP to the remote

- Create traffic classes for maintaining data traffic statistics
per traffic class.
This enables traffic class scoped loss measurement.[edit protocols]user@R1# set mpls statistics traffic-class-statistics
