filterPktStatus

RFC1271-MIB · .1.3.6.1.2.1.16.7.1.1.7

Object

column mandatory r/w Integer32

The status that is to be matched with the input
packet.  The only bits relevant to this match
algorithm are those that have the corresponding
filterPktStatusMask bit equal to one.
              
The following two rules are then applied to every
packet:
              
(1) For each relevant bit from the packet status
    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
              
    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).
