Object
column
r/w
OctetString
Identifies the MEP Linktrace Initiator that is originating,
or the Linktrace Responder that is forwarding, this LTM.
The low-order six octets contain a 48-bit IEEE MAC address
unique to the system in which the MEP Linktrace Initiator
or Linktrace Responder resides. The high-order two octets
contain a value sufficient to uniquely identify the MEP
Linktrace Initiator or Linktrace Responder within that system.
For most Bridges, the address of any MAC attached to the
Bridge will suffice for the low-order six octets, and 0 for
the high-order octets. In some situations, e.g., if multiple
virtual Bridges utilizing emulated LANs are implemented in a
single physical system, the high-order two octets can be used
to differentiate among the transmitting entities.
The value returned is undefined if
dot1agCfmMepTransmitLtmResult is false.
