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.

Type: Modify -- Optional

Valid values: 0 - 65

Default value: -----

mask mask

Mask, used to select the individual bits to be

matched in a packet. If gsvClfrTreeNodeAction is

SetBase and gsvClfrTreeNodeSetBaseType is

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

gsvClfrTreeNodeValType is U8, U16, U32 or U64.

This field is also valid if the

gsvClfrTreeNodeAction is MatchInGenList.

Type: Modify -- Optional

Default value: -----

value 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

gsvClfrTreeNodeAction is SetBase and

NodeSetBaseType is 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

gsvClfrTreeNodeAction is SetPrio or RetagPrio

then this field is used to specify the priority which

is to be assigned to the packet. If the

gsvClfrTreeNodeAction is MatchInGenList then

this

field is not valid. If the gsvClfrTreeNodeAction is

Count, then this field is read only and specifies

total

number of octets of the packets hitting this node.

Action tells what is to be done by a node. 'Drop'

means drop the packet. 'Fwd' means Forward the

packet. 'FwdToCtl' means Forward the packet to

control plane. 'CpToCtl' means forward the packet

and also send a copy of the packet to control

plane.'Allow' means give the packet to the next

stage. 'GoToNextRule' means go to the next rule

(ruleid) attached on that interface and if no next

rule is attached on that interface then forward the

packet. 'Eq' means check if value specified in the

packet is equal to 'Value'. 'Gt' means check if the

value at the location specified in the packet is

greater than 'Value'. 'Lt' means check if the value

at the location specified in the packet is Less than

'Value'. 'InRange' means check if the value at the

location specified in the packet is in the range

specified by 'Value' and 'ValEnd'. 'TerCmp' means

check if the value at the location specified in the

packet is less than, equals to or greater than the

'Value'. 'MatchInList' means take the branch of the

node whose value is equals to the value at the

location specified in the packet. 'AccDeny' means

check if the value at the location specified in the
