filter Packet Data

1.3.6.1.2.1.16.7.1.1.4

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. In particular, a zero length filter will match any packet. This object may not be modified if the associated filterStatus object is equal to valid(1).
