       "This notification indicates that the EFMCu port's data rate

       has reached/dropped below or exceeded the low rate threshold,

       specified by efmCuThreshLowRate.

       This notification MAY be sent for the -O subtype ports

       (2BaseTL-O/10PassTS-O) while the port is Up, on the crossing

       event in both directions: from normal (rate is above the

       threshold) to low (rate equals the threshold or below it) and

       from low to normal.  This notification is not applicable to

       the -R subtypes.

       It is RECOMMENDED that a small debouncing period of 2.5 sec,

       between the detection of the condition and the notification,

       is implemented to prevent simultaneous LinkUp/LinkDown and

       efmCuLowRateCrossing notifications to be sent.

       The adaptive nature of the EFMCu technology allows the port to

       adapt itself to the changes in the copper environment, e.g.,

       an impulse noise, alien crosstalk, or a micro-interruption may

       temporarily drop one or more PMEs in the aggregation group,

       causing a rate degradation of the aggregated EFMCu link.

       The dropped PMEs would then try to re-initialize, possibly at

       a lower rate than before, adjusting the rate to provide

       required target SNR margin.

       Generation of this notification is controlled by the

       When 'enabled', PAF will be performed by the PCS when the link

       PCS ports incapable of supporting PAF SHALL return a value of

       A PAF 'enabled' port with multiple PMEs assigned cannot be

       'disabled'.  Attempts to 'disable' such port SHALL be

       rejected, until at most one PME is left assigned.

       Changing PAFAdminState is a traffic-disruptive operation and

       efmCuPmeAdminProfile, with the desired SNR margin specified by

       efmCuTargetSnrMgn.

       In case of PAF, this object represents a sum of individual PME

       data rates, modified to compensate for fragmentation and

       64/65-octet encapsulation overhead (e.g., target data rate of

       10 Mbps SHALL allow lossless transmission of a full-duplex

       10 Mbps Ethernet frame stream with minimal inter-frame gap).

       The value is limited above by 100 Mbps 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 SHALL 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 the desired

       SNR margin.  In case the copper environment allows a higher

       total data rate to be achieved than that specified by the

       target, the excess capability SHALL be either converted to

       additional SNR margin or reclaimed by minimizing transmit

       power as controlled by efmCuAdaptiveSpectra.

       The value of 999999 means that the target data rate is not

       fixed and SHALL be set to the maximum attainable rate during

       initialization (Best Effort), under specified spectral

       restrictions and with the desired SNR margin.

       This object is read-write for the -O subtype EFMCu ports
