Configuring MPLS-TP OAM for a PW

This section describes how to configure Multiprotocol Label Switching Transport Profile (MPLS-TP) operation, administration and maintenance (OAM) for a pseudo wire (PW). The NetEngine 8000 F can monitor PWs using MPLS-TP OAM.

Usage Scenario

MPLS-TP has been widely used on transport networks. Since traditional transport networks (such as SDH and OTN networks) set high benchmarks for reliability and maintenance, MPLS-TP must provide powerful OAM capabilities.

MPLS-TP OAM can detect faults in a PW and collect performance statistics. On the PW shown in Figure 1, T-PEs are the maintenance entity group end points (MEPs), and S-PEs are the maintenance entity group intermediate points (MIPs). MPLS-TP OAM runs on the MEPs and provides connectivity check, frame loss measurement, and frame delay measurement.

Pre-configuration Tasks

Before configuring MPLS-TP OAM for a PW, complete the following tasks:

Configure a PW over a bidirectional LSP.
Enable performance statistics collection for the attachment circuit (AC) interface of the PW.

Creating an ME Instance and Binding It to a PW: This section describes how to create an ME instance and bind it to a PW.

(Optional) Configuring CC and CV for an LSPa TE-LSP: This section describes how to configure continuity check (CC) and connectivity verification (CV) for an LSP.

(Optional) Configuring LB for an LSP: This section describes how to configure loopback (LB) to monitor the connectivity of MPLS-TP links.

(Optional) Configuring Frame LM: This section describes how to configure frame loss measurement (LM) for MPLS-TP services.

(Optional) Configuring Frame DM: This section describes how to configure one- and two-way frame delay measurement (DM) to collect reliability statistics for MPLS-TP services.

Verifying the Configuration of MPLS-TP OAM for a PW: After configuring Multiprotocol Label Switching Transport Profile (MPLS-TP) operation, administration and maintenance (OAM) for a pseudo wire (PW), verify the configurations by querying performance statistics and fault detection information.
