Command Usage
• Use this command to test the connectivity between maintenance points. If the continuity check
database does not have an entry for the specified maintenance point, an error message will be
displayed.
• The point from which the loopback message is transmitted (i.e., the DSAP) and the target
maintenance point specified in this command must be within the same MA.
• Loop back messages can be used for fault verification and isolation after automatic detection
of a fault or receipt of some other error report. Loopback messages can also used to confirm
the successful restoration or initiation of connectivity. The receiving maintenance point should
respond to the loop back message with a loopback reply.
• When using the command line or web interface, the source MEP used by to send a loopback
message is chosen by the CFM protocol. However, when using SNMP, the source MEP can be
specified by the user.
