Desired EFMCu port 'net' (as seen across MII) Data Rate in Kbps, to be achieved during initialization, under spectral restrictions placed on each PME via efmCuAdminProfile or efmCuPmeAdminProfile, with the desired SNR Margin specified by efmCuTargetWorstCaseSnrMgn and efmCuTargetCurrentConditionSnrMgn depending on the values of efmCuTargetWorstCaseMode and efmCuTargetCurrentConditionMode. In case of PAF, this object represents a sum of individual PME data rates, modified to compensate for fragmentation and 64/65B framing overhead (e.g. target data rate of 10Mbps shall allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). The value is limited above by 100Mbps as this is the max burst rate across MII for EFMCu ports. The value between 1 and 100000 indicates that the total data rate (ifSpeed) of the EFMCu port after initialization should be equal to the target data rate or less, if the target data rate cannot be achieved under spectral restrictions specified by efmCuAdminProfile/efmCuPmeAdminProfile and with desired SNR margin. In case the copper environment allows to achieve higher total data rate than specified by the target, the excess capability SHALL be converted to additional SNR margin and spread evenly across all active PMEs assigned to the (PCS) port. The value of 999999 means that the target data rate is not fixed and should be set to the maximum attainable rate during initialization (Best Effort), under specified spectral restrictions and with desired SNR Margin. This object is read-write for the -O subtype EFMCu ports (2BaseTL-O/10PassTS-O) and not available for the -R subtypes. Changing of the Target Data Rate MUST be performed when the link is Down. Attempts to change this object MUST be rejected with the error inconsistentValue, if the link is Up or Initializing. Note that current Data Rate of the EFMCu port is represented by ifSpeed object of IF-MIB. This object MUST be maintained in a persistent manner.
