Object

column mandatory r/w OctetString

The data that is to be matched with the input packet.
              
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).
