RFC 2020               IEEE 802.12 Interface MIB            October 1996


       D:   0  = No duplicate address has been detected.
            1  = Duplicate address has been detected
       C:   0  = The requested configuration is compatible with the
                 network.
            1  = The requested configuration is not compatible with
                 the network.  In this case, the FF, PP, and R bits
                 indicate the configuration that would be allowed.
       N:   0  = Access will be allowed, providing the configuration
                 is compatible (C = 0).
            1  = Access is not granted because of security
                 restrictions
       r:   Reserved bits (set to zero)
       FF:  00 = frameType88023 will be used
            01 = frameType88025 will be used
            10 = reserved
            11 = reserved
       PP:  00 = singleAddressMode
            01 = promiscuousMode
            10 = reserved
            11 = reserved
       R:   0  = Requested access as an end node is allowed
            1  = Requested access as a repeater is allowed

   Again, note that the most recent version of the IEEE 802.12 standard
   should be consulted for the most up to date definition of the
   requested configuration and allowed configuration fields.

   The data field contains between 594 and 675 octets and is filled in
   by the training initiator.  The first 55 octets may be used for
   vendor specific protocol information.  The remaining octets are all
   zeros.  The length of the training frame combined with the
   requirement that 24 consecutive training frames be received without
   error to complete training ensures that marginal links will not
   complete training.

3.9.  Mapping of IEEE 802.12 Managed Objects

   The following table lists all the managed objects defined for
   oEndNode in the IEEE 802.12 Standard, and the corresponding SNMP
   objects.
