13Configuring ACSEIThe following matrix shows the ACSEI feature and router compatibility:SR6602 SR6602-X SR6604/SR6608/SR6616 SR6604-X/SR6608-X/SR6616-XNo. No.Yes when RPE-X1 and RSE-X1 MPUsare used and no when MCP MPUsare used.Yes.OverviewH3C ACFP Client and Server Exchange Information (ACSEI) provides a method for exchanginginformation between an ACFP server and its ACFP clients. As a supporting protocol for ACFPcollaboration, ACSEI makes sure an ACFP server can cooperate with its ACFP clients to provide services.Like ACFP, ACSEI uses the server/client model:• The ACSEI server is integrated in the Comware software system of the device as a function.• The ACSEI client is integrated in the Comware software system of the device as a function or in thesoftware system of the OAP module as a function.The ACSEI server and the ACFP server run on the same entity. The ACSEI client and the ACFP client runon the same entities.The hardware and configurations needed for the two ACSEI client implementation modes are different.This chapter introduces them separately.For more information about ACFP, see "configuring ACFP." For more information about the OAP module,see "Configuring OAP modules."ACSEI functionsACSEI provides the following functions:• Enables ACFP clients to register and deregister with the ACFP server.• Enables the ACFP server to assign IDs to ACFP clients to distinguish among them.• Allows the ACFP server and an ACFP client to mutually monitor and detect each other.• Supports information interaction between the ACFP server and ACFP clients, including clocksynchronization.• Allows the ACFP server to manage the ACFP clients. For example, you can close or restart an ACFPclient on the ACFP server.An ACFP server supports multiple ACFP clients. An ACFP server allows up to 10 ACFP clients to registerwith.
