Configuring and Initiating OAM Loopbacks
342 Avidia System Configuration and Management User Manual
CONFIGURING AND INITIATING OAM LOOPBACKS
OAM loopbacks enable the testing of PVCs by sending cells from one connection point of a
PVC to another, where they are looped back to the originating point. Before beginning any
OAM loopbacks, ensure that the OAM Source Location ID is set for the Avidia system as
described in the following paragraph.
Setting the System OAM Source Location ID
It is important to set the OAM Source Location ID for the Avidia system, as it enables the
system to determine whether or not it is the originator of received loopback cells. The Source
Location ID default is ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff. Set a unique Location ID prior to
initiating a loopback, as other devices involved in the loopback could default to the same
Location ID. It is recommended that theOAM Source Location ID address for the Avidia
system is set up with:
•a unique address that is meaningful to you for the first 13 octets
•all zeros for the last three octets
Configure the OAM Source Location ID from the ::oam=> prompt.

::oam=> prompt.
