Two OptiX PTN equipment are interconnected through an Ethernet built with switches. Each OptiX PTN equipment is connected to a switch by the FE electrical port.

A static E-Line service carried by an IP tunnel is created between the two NEs. The E-Line service, however, is unavailable.

Please explain and help me, Thank you.

Hello raf_han,

Please note that the causes of this problem are:

  • The IP tunnel is incorrectly configured.

  • The PW that carries the service is faulty.

  • The Ethernet interface is incorrectly configured.

Below the solution of the proposed problem

  1. Query the configuration of the IP tunnel. It is detected that the IP address configurations at both the local interface and opposite interface are correct, and thus the static route is correctly configured.

  2. Check the working status of the PW that carries the E-Line service, and the PW is UP.

  3. Query the basic attributes of the Ethernet interface. It is detected that Port Mode is Layer 2, and Encapsulation Type is 802.1Q. Change Encapsulation Type to NULL, and re-configure the E-Line service. Then, the service is normal.


Thanks

Hello @raf_han

The possible causes are:
Cause 1: The IP tunnel is incorrectly configured.
Cause 2: The PW that carries the service is faulty.
Cause 3: The Ethernet interface is incorrectly configured.

Apply the Procedure as follows:
1. Query the configuration of the IP tunnel. It is detected that the IP address configurations at both the local interface and opposite interface are correct, and thus the static route is correctly configured.
2. Check the working status of the PW that carries the E-Line service, and the PW is UP.
3. Query the basic attributes of the Ethernet interface. It is detected that Port Mode is Layer 2, and Encapsulation Type is 802.1Q. Change Encapsulation Type to NULL, and re-configure the E-Line service. Then, the service is normal.

If Encapsulation Type of an Ethernet interface of the OptiX PTN equipment is set to NULL, the interface transparently transmits the accessed packets and does not process the link-layer encapsulation. In the case of an Ethernet service carried by an IP tunnel, Encapsulation Type of the UNI interface must be set to NULL.
For details on how to query the PW working status, see 2.2.7 Browsing the PW Working Status.
For details on how to configure the Ethernet interface, see Configuring Ethernet Interfaces in the Configuration Guide.


Thanks
