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.
Example
This example sends a loopback message to the specified remote MEP.
Console#ethernet cfm loopback dest-mep 1 md voip ma rd
