Usage Guidelines

Usage Scenario

MPLS-TP OAM is configured for a maintenance entity (ME). An ME consists of two maintenance entity group end points (MEPs) on both ends of a transport path. MPLS-TP OAM detects faults in the MEP. The mpls-tp meg command must be run to create a MEG before MPLS-TP OAM is used.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display information about a MEG named abc.
