Chapter XV. Classification and Filtering
Chelsio T5/T4 Unified Wire For Linux Page 204
1. Introduction
Classification and Filtering feature enhances network security by controlling incoming traffic as
they pass through network interface based on source and destination addresses, protocol,
source and receiving ports, or the value of some status bits in the packet. This feature can be
used in the ingress path to:
 Steer ingress packets that meet ACL (Access Control List) accept criteria to a particular
receive queue.
 Switch (proxy) ingress packets that meet ACL accept criteria to an output port, with
optional header rewrite.
 Drop ingress packets that fail ACL accept criteria.
