Chapter 25 Diagnostic
• Loopback test - checks if the MEP port receives its Loop Back Response (LBR)
from its target after it sends the Loop Back Message (LBM). If no response is
received, there might be a connectivity fault between them.
• Link trace test - provides additional connectivity fault analysis to get more
information on where the fault is. If an MEP port does not respond to the source
MEP, this may indicate a fault. Administrators can take further action to check
and resume services from the fault according to the line connectivity status
report.
