Mutual monitoring and between an ACSEI client and the ACSEI server.
■
Allow information interaction between the ACSEI server and ACSEI
■
clients, including clock synchronization.
Control the ACSEI clients on the ACSEI server. For example, you can
■
close or restart an ACSEI client on the ACSEI server.
An ACSEI server can register multiple ACSEI clients. A Switch 5500G unit
allows an ACSEI server to register up to seven ACSEI clients.
An ACSEI server uses two timers, 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 commands.
The monitoring timer is used to periodically trigger the ACSEI server to
■
send monitoring requests to ACSEI clients. You can set this timer
through commands.
An ACSEI client starts two timers, 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 starts up and runs in the following sequence:
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.
