Configuring ACFP
This chapter describes how to configure the Application Control Forwarding Protocol (ACFP).
Only the LST1IPS1A1, LST1IPS2A1, and LST1ACG1A1 line cards support ACFP.
Overview
ACFP is designed based on the OAA architecture and operates in the server/client model (see Figure 1 ).
In this model, an OAP module (the independent service component) operating as the ACFP client to
provide value-added services such as traffic monitoring, control, and process for the ACFP server (the
routing/switching component).
Figure 1 ACFP architecture
As shown in Figure 1 , the ACFP architecture comprises the following components:
• Routing/switching component—Main part of a routers and a switch. It performs complete
router/switch functions and is also the core of user management control. This part is called the
ACFP server.
• Independent service component—Main part open for development by a third party, mainly used to
provide various unique service functions. This part is called the ACFP client.
• Interface-connecting component—Interface between the routing/switching component and the
independent service component, used to enable the switches of two manufacturers to be
interconnected.
ACFP collaboration
ACFP collaboration means that the independent service component can send instructions to the
routing/switching component to change its functions. ACFP collaboration is mainly implemented through
SNMP. Acting as a network management system, the independent service component sends various
SNMP commands to the routing/switching component, which can then execute the instructions received
because it supports SNMP agent. In this process, the cooperating MIB is the key to associating the two
components with each other.
ACFP management
ACFP collaboration provides a mechanism that enables the ACFP client to control the traffic on the ACFP
server by implementing the following functions:
• Mirroring and redirecting the traffic on the ACFP server to the ACFP client.
• Permitting/denying the traffic from the ACFP server.
