Output field:
Field Description
Tree Name
Name of the classifier tree.
Profile Id
Profile Id. It should be unique within a tree
Node Id
Node Id, should be unique within a profile
Exported
This specifies what fields of an exported node are modifiable and can be modified
while the profile is part of a classifier tree.
Node Type
This specifies the type of the Classifier node
Modification Mask
This specifies what fields of this nodes can be modified, if this node is an
exported node.
Action
Action tells what is to be done by a node.
Value Type
Value type tells, the type of value which is to be matched/set. For leaf type nodes
this field is not valid. If ActVal is SetBase and SBaseType is Compute then this
value is used to specify the value type (U8, U16, U32), which shall be used
to compute the new base offset. This field is not valid for other values of
SBaseType.
Offset
OffSet, in the packet with respect to the base offset, from where we have to take
the value, which is to be matched. If ActVal is SetBase and SBaseType is
Compute then this value is used to specify the offset with respect to the base
offset,
which shall be used to specify the field of the packet used to compute the new
base offset. If the valuetype is U8 the offset can be odd or even. If the ValueType
is U16, U32 or U64 then the offset can only be even. This field is not valid for any
other value type.
Mask
Mask, used to select the individual bits to be match in a packet. If ActVal is
SetBase and SBaseTypeis Compute then this value is used to specify the mask,
which shall be used to identify the individual bits of the field of the packet used to
compute the new base offset.This field is valid only if the ValueType is U8, U16,
U32 or U64. This field is also valid if the ActVal is MatchInGenList.
Value
Value, to be matched. For NonLinear node types, this field is not valid. For Linear
node types, this value is used to specify the start of the range. if ActVal is
SetBase and SBaseTypeis Compute then this field is used to specify the value,
which is to be added to base offset to calculate new base offset. If the ActVal is
SetPrio or RetagPrio then this field is used to specify the priority which is to be
assigned to the packet. If the ActVal is MatchInGenList then this field is not valid.
If the ActVal is Count then this field is read only and specifies total number of
octet of the packets hitting this node.
ValueEnd
For Linear nodes this field is used to specify the end of the range. If the ActVal is
InRange then this field is used to specify the end of the range. If the ActVal is
count then this field is used to specify the total number of packet hitting this node.
