You can perform a link trace (LT) check on Ethernet services to check the MIP information in the link for locating and handling faults.
Prerequisites
- The source and sink MEPs, and MIPs in the same maintenance domain must be created.
- Only MEPs can initiate the LT test and work as the termination point in the test.
- The Ethernet board must be created.
Background Information
- During the LT check, the source MEP constructs and transmits LTM frames and starts the timer. All the MPs that receive the LTM frames send the LTR frame response. According to the LTR frame response, you can verify all the MIPs that pass from the
source MEP to the destination MEP.
- Performing an LT check does not affect the service.
Procedure
- In the NE Explorer, select an Ethernet board and choose from the Function Tree.
- Select the node that you want to monitor, click OAM Operation and select . The LT Test dialog box is displayed.
- Enter the LT test source maintenance point ID and sink maintenance point ID.
NOTE: Before you perform the check, set an appropriate LT Timeout (ms) as required.
- Click Start LT and the check result is displayed.
