Probe operation

The probe connects to the Nortel EAI as a TCP/IP client. If the connection fails or if the connection is not made within the time specified by the ConnectionTimeout property, the probe waits for the amount of time specified by the PauseTime property before trying the connection again.

Once connected, the probe waits for the first heartbeat message from the interface. It expects to receive the first heartbeat within the time specified by the EAIHeartbeatTimeout property. If the probe does not receive a heartbeat message within this time, it disconnects from the interface, waits for the time specified by the PauseTime property and reconnects to the interface. If the probe receives the first heartbeat message within this time, it then waits to receive subsequent heartbeat messages. If the EAIHeartbeatTimeout property is set to 0, the probe does not wait for the first heartbeat message from the interface.

After receiving the first heartbeat, the probe expects to receive either a new alarm or a heartbeat message within the time specified by the EAIHeartbeatInterval property. If the probe does receive an alarm or a heartbeat message within this time, it restarts the connection to the interface or starts failover processing. You can control the number of times the probe restarts the connection using the RestartOnIdleTimeout property. If this property is set to 0, the probe makes unlimited attempts to reconnect to the interface. If this property is set to 1, the probe disconnects from the interface and does not attempt to reconnect. If this property is set to a value greater than 1, the probe makes this number of reconnection attempts (minus one) to the device before exiting.
