ACSEI overview
As a private protocol, ACSEI provides a method for exchanging information between ACFP clients and ACFP server. It supports Application Control Forwarding Protocol (ACFP) collaboration, ensuring valid information interaction between the ACFP clients and the ACFP server, so that the ACFP clients and server can cooperate to run a service.
As a supporting protocol of ACFP, ACSEI also has a server and a client:
· The ACSEI server is integrated into the software system of the switch and is supported by the switch.
· The ACSEI client is integrated into the software system of an open application platform (OAP) module and is supported by the OAP module.

NOTE: · ACFP is designed based on the Open Application Architecture (OAA). · OAP is designed for new services. On OAP module runs the operating system. You can load various service software, such as security, voice, and others needed. For more information about the OAP module, see the chapter “Configuring the OAP card.” · ACSEI is typically used in combination with the QoS policy (traffic redirecting function). With ACSEI enabled, when an IPS, ACG, FW, or ACG card fails, ACSEI sets the QoS policy as ineffective when it detects any abnormality of the ACSEI client, and disables the traffic from being redirected, thus to implement the function like ACFP so that traffic forwarding is not affected. · This manual covers the configuration of the ACSEI server integrated into the software system of the switch. |
ACSEI functions
ACSEI provides the following functions:
· Registration and deregistration of an ACSEI client to the ACSEI server.
· ID assignment. The ACSEI server assigns IDs to ACSEI clients to distinguish between them.
· Mutual monitoring and awareness between an ACSEI client and the ACSEI server.
· Information interaction between the ACSEI server and ACSEI clients, including clock synchronization.
· Control of the ACSEI clients on the ACSEI server. For example, you can restart ACSEI client on the ACSEI server.
ACSEI timers
An ACSEI server uses the clock synchronization timer and the monitoring timer:
· The clock synchronization timer is used to periodically trigger the ACSEI server to send clock synchronization advertisements to ACSEI clients. You can set this timer through command lines.
· The monitoring timer is used to periodically trigger the ACSEI server to send monitoring requests to ACSEI clients. You can set this timer through command lines.
An ACSEI client starts the registration timer and the monitoring timer:
· The registration timer is used to periodically trigger the ACSEI client to multicast registration requests (with the multicast MAC address being 010F-E200-0021). You cannot set this timer.
· The monitoring timer is used to periodically trigger the ACSEI client to send monitoring requests to the ACSEI server. You cannot set this timer.
ACSEI startup and running
ACSEI starts up and runs in the following procedures:
1. Run the ACSEI client application to enable ACSEI client.
2. Start up the switch and enable the ACSEI server function on it.
3. The ACSEI client multicasts registration requests.
4. After the ACSEI server receives a valid registration request, it negotiates parameters with the ACSEI client and establishes connection with the client if the negotiation succeeds.
5. The ACSEI server and the ACSEI client mutually monitor the connection.
6. If detecting the disconnection of the ACSEI client, the ACFP server will remove the configuration and policies associated with the client.
