How to Configure PW-Based E-Line Services in an end-to-end Mode

• You must be an NM user with NE administrator authority or higher.
• Parameters related to UNI ports have been configured correctly.

Procedure

1. Choose Service > PWE3 Service > Create PWE3 Service from the Main Menu.
2. Set the basic attributes of a PW-based E-Line service.

• Service template: If no service template has been specified, set this parameter to DEFAULT_PWE3_ETH_PTN/ATN.
• Service Type: ETH
• Protection Type: Protection-Free
• Service ID and Service Name: Unless otherwise specified, these two parameters take their default values. The U2000 automatically generates the parameter values according to the service naming rules.

3. Configure the NEs and service ports on the NEs that are involved in the PW-carried E-Line service.

a.  Double-click the source NE in the Physical Topology tab page.

b.  Select the service port on the source NE, configure its VLAN ID, and click OK.

§  Set VLAN ID to the VLAN ID planned for the Ethernet services over the UNI port.

§  If you do not configure VLAN ID, Ethernet services exclusively occupy the UNI port.

c.  Repeat 3.a and 3.b to configure the service port on the sink NE.

The information about the source and sink NEs is displayed in Node List.

d.  Optional: In the Physical Topology tab page, right-click the S-PE and choose Set As Switching Node > Working from the shortcut menu.

NOTE:

To create an unterminated PWE3 service, of which the PE at one end is unreachable on the U2000, right-click the service in the physical topology and choose corresponding options from the shortcut menu to create the service source or sink (a virtual node).

      Set the basic attributes of PWs.

o    Forward Tunnel and Reverse Tunnel: If there are end-to-end working MPLS tunnels between PEs, the U2000 automatically generates the parameter values. If the tunnels generated by the U2000 are different from the planned tunnels, select correct tunnels if the tunnels have already been created or create the desired tunnels.

o    PW ID, Forward Label, and Reverse Label: Set these parameters according to the service planning information. If the parameter values are not specified in the service planning information and the entire network is managed by the U2000, the U2000 automatically allocates values for these parameters.

      Optional: Set the advanced attributes of PWs.

 .  Click Detail.

a.  In the PW QoS tab, configure QoS of the PWs.

Unless otherwise specified, it is recommended that all parameters in the tab take their default values.

b.  In the Advanced PW Attribute tab, set advanced attributes of the PWs.

§  PW Type: This parameter specifies whether a P-TAG is added to the Ethernet frames that are encapsulated to a PW. If a P-TAG does not need to be added to Ethernet frames that are encapsulated to a PW, set this parameter to Ethernet. If a P-TAG needs to be added to Ethernet frames that are encapsulated to a PW, set this parameter to Ethernet Tagged Mode and set the desired Request VLAN.

§  Control Word: Not in use

§  Control Channel Type: This parameter specifies the PW connectivity detection mode. Alert Label indicates that VCCV packets in Alert Label encapsulation mode are used for PW connectivity detection. None indicates that VCCV is not used.

      At the lower left corner, select Deploy and Enable.

If you select Deploy, the service configuration data is saved on the U2000 side and deployed to the NE side. If you do not select Deploy, the service configuration data is saved on the U2000 side but is not deployed to the NE side.

      Click OK.

      In the Operation Result dialog box that is displayed, select Browse Trail.

The new Ethernet PWE3 service is displayed in the PWE3 service list.
