PM2329 ClassiPI Network Classification Processor Datasheet
TTL Equal to 0
This bit is valid only if the OC Type was Header.
This bit is set to
1
to indicate that the Time To Live field within the IP header is
0
. This field is valid
only if no extraction error occurred and it was not a pre-extracted header packet.
Cascade OC Enable
This field contains a copy of the Cascade OC Enable field from the OCC of the packet corresponding to
this result.
Data Result Available
The condition when this bit is set are as follows:
1. OCC controlled sequencing is selected,
2. D-Word Update Enable was set for this OC,
3. ECR defined at least one D-Word, and
4. the OC results in a match condition.
or
1. E-RAM controlled sequencing is selected,
2. D-Word Update Enable was set for this OC,
3. ECR defined at least one D-Word,
4. the OC results in a match condition, and
5. the specified branch opcode was not Terminate.
If this bit is set, then some E-RAM data fields were either read or updated and are present in the Data
Results FIFO. The operation of the Data Results FIFO is linked to the reading out of the OC Results
FIFO. The Data Results, if required, should be read out before the next read access to the OC Results
FIFO.
Match Rule Attribute
This bit is valid only if the OC Match bit is set.
This bit is a copy of the Attribute bit within the rule for the cell which matched.
Match Cell Number
This field is valid only if the OC Match bit is set to
1
.
This field returns the 17-bit cell number of the rule within the partition that resulted in the match. This
cell number corresponds to a relative cell number, i.e., the cell number within the OC partition across
multiple PM2329 devices regardless of the physical partition fragmentation within a device or across
multiple devices.
