z Control of the ACSEI clients on the ACSEI server. For example, you can close ACSEI client, or
restart ACSEI client on the ACSEI server.
An ACSEI server can register multiple ACSEI clients. The maximum number of ACSEI clients that an
ACSEI server allows to register is 10.
ACSEI Timers
An ACSEI server uses two timers, the clock synchronization timer and the monitoring timer.
z 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.
z 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.
z An ACSEI client starts two timers, the registration timer and the monitoring timer.
z 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.
z 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 device 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.
