-- The Host Top "N" Group
-- Implementation of the Host Top N group is optional.
--
-- The Host Top N group requires the implementation of the

--
-- The Host Top N group is used to prepare reports that
-- describe the hosts that top a list ordered by one of

-- of one of their base statistics, over an interval
-- specified by the management station. Thus, these
-- statistics are rate based. The management

-- The hostTopNControlTable is used to initiate the generation

-- which statistic, how many hosts, and the start and stop
-- times of the sampling. When the report is prepared,
-- entries are created in the hostTopNTable associated with
-- the relevant hostTopNControlEntry. These entries are
-- static for each report after it has been prepared.

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

then the packet will fail this data match.
(3) If for every relevant bit from the packet with the

In addition, at least one of those relevant

For the purposes of the matching algorithm, if

filterPktStatus OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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)."
