                  For each packet received, this filter and the
                  accompanying filterPktDataMask and
                  filterPktDataNotMask will be adjusted for the
                  offset.  The only bits relevant to this
                  match algorithm are those that have the corresponding
                  filterPktDataMask bit equal to one.  The following
                  three rules are then applied to every packet:

                  (1) If the packet is too short and does not have data
                      corresponding to part of the filterPktData, the
                      packet will fail this data match.

                  (2) For each relevant bit from the packet with the
                      corresponding filterPktDataNotMask bit set to
                      zero, if the bit from the packet is not equal to
                      the corresponding bit from the filterPktData,
                      then the packet will fail this data match.

                  (3) If for every relevant bit from the packet with the
                      corresponding filterPktDataNotMask bit set to one,
                      the bit from the packet is equal to the
                      corresponding bit from the filterPktData, then
                      the packet will fail this data match.

                  Any packets that have not failed any of the three
                  matches above have passed this data match.

                  This object may not be modified if the associated
                  filterStatus object is equal to valid(1)."

                  The following two rules are then applied to every

                      with the corresponding filterPktStatusNotMask
                      bit set to zero, if the bit from the packet
                      status is not equal to the corresponding bit
                      from the filterPktStatus, then the packet will
ToP   noToC   RFC1271 - Page 60
                      fail this status match.

                  (2) If for every relevant bit from the packet status
                      with the corresponding filterPktStatusNotMask
                      bit set to one, the bit from the packet status
                      is equal to the corresponding bit from the
                      filterPktStatus, then the packet will fail
                      this status match.

                  Any packets that have not failed either of the two
                  matches above have passed this status match.

                  The value of the packet status is a sum.  This sum
                  initially takes the value zero.  Then, for each
                  error, E, that has been discovered in this packet,
                  2 raised to a value representing E is added to the sum.
                  The errors and the bits that represent them are
                  dependent on the media type of the interface that
                  this channel is receiving packets from.

                  The errors defined for a packet captured off of an
                  Ethernet interface are as follows:

                      bit #    Error
                          0    Packet is longer than 1518 octets
                          1    Packet is shorter than 64 octets
                          2    Packet experienced a CRC or Alignment
                               error

                  For example, an Ethernet fragment would have a
                  value of 6 (2^1 + 2^2).

                  As this MIB is expanded to new media types, this
                  object will have other media-specific errors defined.

                  For the purposes of this status matching algorithm, if
                  the packet status is longer than this
                  object, filterPktStatus this object is conceptually
                  extended with '0' bits until it reaches the size of
                  the packet status.

                  This object may not be modified if the associated
                  filterStatus object is equal to valid(1)."
