Redundant Servers — Only available for Server 1
If the redundant server is configured, whenever a report is sent to server 1, an identical report is sent to any configured
redundant server(s). Transport/SNF configuration settings do not apply to redundant servers. Commands from redundant
servers are ignored. Reports originate from port 17335. The redundant servers can be a local host or a remote server
that is accessed over-the-air or via a VPN tunnel.

Transport / Store and Forward (SNF)
This feature is designed to accommodate periods when the AirLink gateway is outside the area of mobile network
coverage or otherwise unable to reach the report server. Reports are stored and then "forwarded" in a combined packet
when the device is again able to contact the server.
There are four Location servers and five Events Reporting servers. Each server has its own buffer and can store a
maximum of 395 reports. The maximum length of each report is 255 bytes. Note that this is separate from any SNF done
by AAF applications, including the AirLink Vehicle Telemetry Application (AVTA).

Store and Forward causes location reports to be stored if the AirLink gateway goes out of
network coverage. Once the device/vehicle is in coverage the stored location reports are
sent to the server. Options are:
Disable (default)—If there is no mobile network coverage, reports are not stored.
•
Enable—If there is no mobile network coverage, reports are stored until the AirLink
•
gateway can access the server.
Note: You can also use an AT Command to set this value. For more information, see
*PPSNF on page 451.
