1.4 DAG 4.3GE Card Extended Functions
Description
The DAG 4.3GE card is equipped with a coprocessor connector which can
be used with the optional Endace DAG Coprocessor as a data processing
tool.
The IP packet classification specifications are:
•
Packets are classified by TCP/IP header fields and/or payload
content.
•
Up to 16,384 TCP/IP header classification rules. Up to ~2,000
arbitrary payload search strings.
•
Classification rules are assigned a user-defined 16-bit identifier
•
Packets matching classification rules are assigned the matching
rule's identifier.
•
Programmable actions may be associated with each rule identifier.
For example, The packet should either be dropped, retransmitted to
the network, or presented to the host.
•
Packets presented to the host include the rule-match identifier in the
record header.
