| Description | 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
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
(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
(in case of SNMP with the error inconsistentValue), if the
link is Up or Initializing.
Note that the current Data Rate of the EFMCu port is
represented by the ifSpeed object of IF-MIB.
This object MUST be maintained in a persistent manner. |
