•
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.
