Testing EoS Services

Testing EoS Services

After configuring an EoS service, you need to check whether the EoS service is available.

Testing EoS Service Availability Using ETH OAM

The ETH OAM function allows you to test availability of an EoS channel without the need for test instruments.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • EoS services have been configured between two sites. For details on how to configure EoS services, see Configuring Ethernet Services.
  • OAM maintenance points have been configured at the two sites.
Tools, Equipment, and Materials

U2000

Background Information

For the OptiX OSN equipment, you can refer to the Availability about the ETH OAM function in the Feature Description for details about the boards that support the ETH OAM function.

Procedure

  1. In the Main Topology, right-click the NE icon and choose NE Explorer from the shortcut menu.
  2. Select the Ethernet board in the Object Tree and choose Configuration > Ethernet Maintenance > Ethernet Service OAM from the Function Tree.
  3. In the right pane, click OAM Configuration. The OAM Configuration dialog box is displayed.
  4. Click New. Then, select New Maintenance Domain from the drop-down menu.
  5. In the New Maintenance Domain dialog box, set Maintenance Domain Name and select Maintenance Domain Level.
  6. Click OK. Operation Successed is displayed in the Result dialog box. Click Close.
  7. In the OAM Configuration dialog box, click New and choose New Maintenance Association from the drop-down menu.
  8. In the New Maintenance Association dialog box, set Maintenance Domain Name and Maintenance Association Name.
  9. Click OK. Operation Successed is displayed in the Result dialog box. Click Close.
  10. Close the OAM Configuration dialog box.
  11. Navigate to the Ethernet Service OAM interface. Click New. In the Create MP dialog box that is displayed, set related parameters.



  12. Click OK. Operation Successed is displayed in the Result dialog box. Click Close.
  13. In Ethernet Service OAM, right-click the created Ethernet service maintenance point, and choose Performance Detect from the shortcut menu.
  14. The Performance Detect dialog box is displayed. In Send Mode, select the specific mode. In Maintenance Point, set Source MP ID and Destination MP ID.

  15. Click Start Detect. The statistics of the performance is displayed in the Details. View the results of the statistics. Then, determine the performance of the service between the local equipment and the opposite equipment through Loss Ratio and Delay.
  16. Change the length of the frame in Send Mode. Then, test and record the loss ratio and delay of the packets with the length of 128, 256, 512, 1024, 1280, and 1518 bytes.

Testing EoS Service Performance by Using SmartBits

You can check whether the performance of an EoS service by looping back the service at one end and testing packet loss with a SmartBits at the other end.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • EoS services have been configured. For details on how to configure EoS services, see Configuring Ethernet Services in the Configuration Guide.
Tools, Equipment, and Materials
  • Data network performance analyzer
  • U2000
Connection Diagram for the Test

Figure 1-17 shows a connection diagram for testing EoS services.

Figure 1-17  Connection diagram for testing EoS services

NOTE:
The connection diagram is only an example. In this example, a MAC-layer inloop is performed on an Ethernet port on NE1, and the SmarBits is connected to an Ethernet port on NE2.
Precautions
  • Keep irrelevant personnel away from the testing environment during a test.
  • Do not touch fibers, electrical wires, or cables unless necessary.

Procedure

  1. According to the test connection diagram, connect the SmartBits to the Ethernet port on NE2.
  2. Log in to the U2000. Follow instructions in Enabling NE Performance Monitoring to enable 15-minute and 24-hour performance monitoring for NE1 and NE2.

    NOTE:
    Performance monitoring needs to be enabled in case that a fault detected in the test can be located.

  3. Log in to the U2000 and set a MAC-layer inloop for the Ethernet port on NE1.
    1. In the Workbench view, double-click Main Topology to display the main topology.
    2. Right-click the NE to be looped back on the Main Topology of the U2000, and choose NE Explorer from the shortcut menu.
    3. Select the Ethernet board to be looped back, and choose Configuration > Interface Management > Ethernet Interface from the Function Tree.
    4. Select Advanced Attributes.
    5. In the list, select an Ethernet interface, and then double-click PHY Loopback or MAC Loopback to select a loopback mode.
    6. Click Query. After the Prompt dialog box is displayed, click OK.
    7. After the Operation Result dialog box is displayed, click Close.
  4. Use the SmartBits to perform tests on packet receiving and transmission.

    NOTE:
    • Packets with all 0s are regarded as special packets. Therefore, do not use packets of all 0s for testing transmitted and received packets.
    • When the SmartBits transmits and receives packets for the first time, packet loss occurs due to MAC address learning. Therefore, it is normal that the number of transmitted packets is different from the number of received packets.
    • In the tests after the first time, if the number of transmitted packets is the same as the number of received packets, the cross-domain service channels are normal.
    • If packet loss occurs during the tests, troubleshoot the fault and then perform 24-hour tests until the channels pass the tests.
