Release: Any
For example, let's say for a device that the poll interval is 5 minutes, the DCM Timeout and DCM Trycount values are 3000ms and 3.
At the 5 minute mark, Spectrum sends an SNMP get-request with a timestamp of 9:43:14 to the device and that SNMP has a request-id of 18846920.
No response is received within 3 seconds, so another SNMP get-request is sent to the device with request-id of 18847047 and a timestamp of 9:43:17.
The device sends a get-response to Spectrum with a request-id of 18846920 and it has a timestamp of 9:43:20. This is 6 seconds after the SNMP get-request was sent with the same request-id. Since this is over the 3000ms mark, Spectrum does not consider this to be acceptable contact.
Spectrum sends another SNMP get-request at 9:43:20 with a request-id of 18847076.
The device sends a get-response at 9:43:23 with a request-id of 18847047. This is 5 seconds after the SNMP get-request was sent with the same request-id so again, Spectrum does not consider this to be acceptable contact.
The device sends a get-response to Spectrum with a request-id of 18847076 and it has a timestamp of 9:43:26. This is 6 seconds after the SNMP get-request was sent with the same request-id so again, Spectrum does not consider this to be acceptable contact and since the TryCount value has now been reached (3) Spectrum generates a Management Agent Lost Alarm.
