The Target or Destination MAC Address Field to be transmitted. If osSoamPmDmPrflType is 'dmDmm', the destination address is to be the unicast address of the destination MEP. An error is returned if this object is set to a multicast address. If osSoamPmDmPrflType is 'dm1DmTx', the destination address is normally the unicast address of the destination MEP, but can be a multicast address indicating the level of the MEG: 01-80-c2-00-00-3y, where y is the level of the MEG. An error is returned if this object is set to any other multicast address. If osSoamPmDmPrflType is 'dm1DmRx', this object is ignored. This address will be used if the value of the object osSoamDmDestIsMepId is 'false'. This object is only valid for the entity transmitting the SOAM DM frames and is ignored by the entity receiving SOAM DM frames. This object can only be written at row creation time and cannot be modified once it has been created.
