Abstract: In one embodiment, a network device is provided that comprises a plurality of ports at which network packets are received at the network device and sent from the network device. At least hardware module includes one or more memories that store entries for one or more networking features to be performed to direct network packets with respect to the plurality of ports. A processor is coupled to the at least one hardware module and configured to communicate with the at least one hardware module to store in the one or more memories attributes for one or more access control lists and associated actions that cause network packets which are received that match the attributes for the one or more access control lists, to be directed in a service chain that includes one or more network processing appliances connected to one or more of the plurality of ports.
