Managing MPLS Tunnels

Managing MPLS Tunnels

MPLS tunnels are used to transmit PWE3 services and their quality determines transmission stability of PWE3 services. Therefore, it is crucial to properly manage MPLS tunnels. Managing MPLS tunnels involves checking the MPLS tunnel topology, deploying MPLS tunnels, deleting MPLS tunnels, and managing discrete MPLS tunnels.

Searching for MPLS Tunnels

A complete MPLS tunnel has its source and sink NEs. An MPLS tunnel that is created on a per-NE basis, however, is displayed as a discrete tunnel on the NMS. The tunnel search function on the NMS helps convert a discrete MPLS tunnel to a complete tunnel, therefore facilitating tunnel management. This section describes how to search for MPLS tunnels on the NMS.

Prerequisites

  • MPLS tunnels have been created on a per-NE basis. For details on how to create an MPLS tunnel on a per-NE basis, see Configuring an MPLS Tunnel on a Per-NE Basis.
  • You are an NM user with Administrators rights or higher.

Procedure

  1. Choose Service > Search for IP Service from the main menu.
  2. In the dialog box that is displayed, set the tunnel discovery policy.



  3. Click Start.
  4. Click Close.

Checking the MPLS Tunnel Topology

MPLS tunnels are used to transmit PWE3 services and their quality determines transmission stability of PWE3 services. This section describes how to check the MPLS tunnel topology to learn configuration information about MPLS tunnels, facilitating tunnel management.

Prerequisites

  • MPLS tunnels have been created. For details on how to create an MPLS tunnel, see Configuring an MPLS Tunnel.
    NOTE:
    Before managing an MPLS tunnel that is created on a per-NE basis, you need to search for the MPLS tunnel. For details on how to search for an MPLS tunnel, see Searching for MPLS Tunnels.
  • You are an NM user with Administrators rights or higher.

Procedure

  1. Choose Service > Tunnel > Manage Tunnel from the main menu.
  2. In the dialog box that is displayed, set filter conditions; for example, set Protocol Type to MPLS and set Signaling Type to Static CR. Then, click Filter. Query all MPLS tunnels that meet the filter conditions.
  3. Select the MPLS tunnel whose topology information you need to check and click the Topology tab.
  4. In the MPLS tunnel topology view, right-click the NE and choose View Real-Time Performance from the shortcut menu to check the real-time running status of the MPLS tunnel.

Deploying MPLS Tunnels

After being created on the NMS, MPLS tunnels are stored on the NMS but not immediately deployed to the corresponding NEs. This section describes how to deploy MPLS tunnels from the NMS to the corresponding NEs.

Prerequisites

  • MPLS tunnels have been created. For details on how to create an MPLS tunnel, see Configuring an MPLS Tunnel.
    NOTE:
    Before managing an MPLS tunnel that is created on a per-NE basis, you need to search for the MPLS tunnel. For details on how to search for an MPLS tunnel, see Searching for MPLS Tunnels.
  • You are an NM user with Administrators rights or higher.

Procedure

  1. Choose Service > Tunnel > Manage Tunnel from the main menu.
  2. In the dialog box that is displayed, set Deployment Status to Undeployed. Click Filter to check all undeployed MSPLS tunnels.
  3. Select one or more MPLS tunnels to be deployed, right-click the MPLS tunnels, and choose Deploy and Enable > Deploy from the shortcut menu.



    NOTE:
    After an MPLS tunnel is successfully deployed, its Deployment Status is Deployed.

Modifying MPLS Tunnels

This section describes how to modify MPLS tunnels in end-to-end mode and on a per-NE basis.

Prerequisite
  • MPLS tunnels have been created. For details on how to create an MPLS tunnel, see Configuring an MPLS Tunnel.
    NOTE:
    Before managing an MPLS tunnel that is created on a per-NE basis, you need to search for the MPLS tunnel. For details on how to search for an MPLS tunnel, see Searching for MPLS Tunnels.
  • You are an NM user with Administrators rights or higher.
Background Information

Modifying an MPLS tunnel may interrupt services.

Modifying an MPLS Tunnel in End-to-End Mode
  1. Choose Service > Tunnel > Manage Tunnel from the main menu.
  2. In the dialog box that is displayed, set filter conditions; for example, set Protocol Type to MPLS and set Signaling Type to Static CR. Then, click Filter. Query all MPLS tunnels that meet the filter conditions.
  3. Select the desired tunnel information and click the Hop Information tab. Then, modify the tunnel parameters.



  4. Optional: If only the basic attributes of a tunnel need to be modified, select the desired tunnel and choose Details from the shortcut menu. Then, modify the basic attributes of the tunnel.
  5. Click Apply.
Modifying an MPLS Tunnel on a Per-NE Basis
  1. Select the source NE of the tunnel from the NE Explorer. Choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management from the Function Tree. Then, click the Static Tunnel tab.
  2. Select the tunnel information and click Modify. Then, modify the tunnel parameters.

  3. Click OK. The Warning dialog box is displayed, prompting a possibility of service interruption.
  4. Click OK. The Result dialog box is displayed.
  5. Click OK.
  6. Repeat steps 1-5 to modify the tunnels on intermediate NEs and sink NE.

Deleting MPLS Tunnels

After being deployed, MPLS tunnels are stored on the NMS and the corresponding NEs. This section describes how to delete MPLS tunnels from the NMS and corresponding NEs.
