Supports arbitrary pattern match classification.
Up to 128 bytes of data within the first 128 bytes
of a packet can be identified for pattern matching
purposes. This object and the
ntnSystemClfrPatternPosition object specify byte
patterns and their position in a packet. When a
packet is classified using this data, the appropriate
bytes, or portions thereof, in the packet are compared
against the byte patterns defined by the this
attribute. If the data at the specified packet offset
is the same, the packet is considered a match.
The byte patterns used for comparison purposes
are specified using this attribute. The target
data is placed in the octet string at the
positions specified through the
ntnSystemClfrPatternPosition attribute. All
other bytes should be set to zero
For example, to specify that byte positions 5-8
and the high-order nibble (4 bits) of bytes 13-16
should be examined, the associated
ntnSystemClfrPatternPosition value would be set
as follows:
ntnSystemClfrPatternPosition (size 16):
00:00:00:00:FF:FF:FF:FF:00:00:00:00:0F:0F:0F:0F
The target byte patterns would then be placed
in bytes 5-8 and in portions of bytes 13-16 of
this attribute:
ntnSystemClfrPatternData (size 16):
00:00:00:00:XX:XX:XX:XX:00:00:00:00:0Y:0Y:0Y:0Y
Note that an implementation may not support pattern
matching, also know as offset filtering, for the
maximum number of bytes supported by the pattern
match attributes. The number of bytes that can
contain data for comparison purposes and the position
of those bytes in relation to the start of a packet
are thus implementation dependent.
Use of this object and the associated
ntnSystemClfrPatternPosition object invalidates
the use of any other classification data in
this and related (through the ntnClfrComponentTable)
classifier entries. In other words, providing
an explicit pattern overrides the implicit
patterns defined when classification data is
specified for other fields, such as the IP source
address or EtherType classification attributes.
A zero length string is used to indicate that
explicit pattern matching is not requested.
