| Description | This 18 bit field is used to indicate the result
of training. It contains two bits which indicate
if error-free training frames have been received,
and it also contains the 16 bits of the allowed
configuration field from the most recent
error-free training response frame on the port.

+-+-+-+-+-+-+-+-+-----------------------------+
V: Valid: set when at least one error-free
training frame has been received.
Indicates the 16 training configuration
bits in vgRptrPortLastTrainConfig and
vgRptrPortTrainingResult contain valid
information. This bit is cleared when
vgRptrPortStatus transitions to the
'inactive' or 'training' state.
G: LinkGood: indicates the link hardware is
OK. Set if 24 consecutive error-free
training packets have been exchanged.
Cleared when a training packet with
errors is received, or when
vgRptrPortStatus transitions to the
'inactive' or 'training' state.
The format of the current version of the allowed
configuration field is described in section 3.2.
Please refer to the most recent version of the
IEEE 802.12 standard for the most up-to-date
definition of the format of this field.
If the port is in training, a management station
can examine this object to see if any training
packets have been passed successfully. If there
have been any good training packets, the Valid
bit will be set and the management station can
examine the allowed configuration field to see if
there is a duplicate address, configuration, or
security problem.
Note that on a repeater local port, this repeater
generates the training response bits, while on
a cascade port, the device at the upper end of
the link originated the training response bits. |
