Using MPLS-TP Commands

---

MPLS-TP is a carrier-grade packet transport technology that enables the move from SONET and SDH time-division multiplexing (TDM) to packet switching. MPLS-TP enables MPLS to be deployed in a transport network and to operate similarly to existing transport technologies. MPLS-TP enables MPLS to support packet transport services with a degree of predictability that is similar to the existing transport networks.

The goal of MPLS-TP is to provide connection-oriented transport for packet and TDM services over networks leveraging the widely deployed MPLS technology. Operations, administration, and maintenance (OAM) and resiliency features are defined and implemented in MPLS-TP to ensure:

•Scalable operations

•High availability

•Performance monitoring

•Multidomain support

•Carrier-grade packet transport networks

An MPLS-TP tunnel has:

•Two endpoints where the tunnel is configure as a tunnel interface

•One or two bidirectional label switched path (LSP) pairs between the endpoints. If there are two pairs, then one is a working path, the second a protection path.

•Pair of bidirectional LSPs that are congruent.

•Where there is no control plane, the LSPs are configured at all the midpoints.

•The MPLS-TP tunnel is used to carry pseudowires.

Supported Network Elements

You can run the MPLS-TP commands on the following network elements:

•Cisco 7600 Series Routers

•Cisco CPT Devices.

Configuring MPLS-TP Components

The following commands facilitate the configuration of MPLS-TP components:

•MPLS-TP Tunnel Ping

•MPLS-TP Tunnel Trace

•LSP Path Lockout

MPLS-TP Tunnel Ping

Use the MPLS-TP Tunnel Ping command to ping the MPLS-TP tunnel.

---

Step 1 In the inventory window, expand the Logical Inventory tree and MPLS-TP node.

Step 2 Right-click and choose MPLS-TP Global > Commands > Configuration > MPLSTP Tunnel Ping.

Step 3 Enter values for the following parameters

.

Input Parameter	Description
TunnelId	The unique identifier of the MPLS-TP tunnel. The range of the tunnel is from 1 to 65535
LSP Path	The LSP path information- path, working.

Step 4 To see the commands that will be applied on the device, click Preview.

You can view the commands in the Result tab. You can go back and make any required changes to the input parameters.

Step 5 To schedule the command, click the Scheduling tab. For more details on scheduling, see Scheduling a Command.

Step 6 To run the commands, click Execute Now.

Any errors are displayed in the Result tab.

Step 7 To close the dialog box, click Close.
