Redundant Servers—Only available for Server 1
If the redundant server is configured, anytime 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.
Redundant Server 1
IP Address
IP address or FQDN of the first redundant server
Redundant Server 1
Port Number
Port number of the first redundant server
The port number can be the same as or different from that of other servers.
Redundant Server 2
IP Address
IP address or FQDN of the second redundant server
Redundant Server 2
Port Number
Port number of the second redundant server
The port number can be the same as or different from that of other servers.
Minimum Report Time
(secs)
Specifies the minimum time (in seconds) between partial reports or grouped packets being
sent
You can also use an AT Command to set this value. For more information, see
*PPMINTIME on page 357.
Transport/Store and Forward (SNF)—This feature is designed to accommodate periods when the AirLink
device is outside the area of cellular 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.
Enable SNF for
Unreliable Mode
Store and Forward causes GPS reports to be stored if the AirLink Device goes out of
network coverage. Once the device/vehicle is in coverage the stored GPS reports are sent
to the server. Options are:
• Disable (default)—If there is no cellular network coverage, reports are not stored.
• Enable—If there is no cellular network coverage, reports are stored until the AirLink
device can access the server.
Note: When you are using GPS and Wi-Fi Client mode: If the Wi-Fi client is connected,
reports are sent over the Wi-Fi WAN connection rather than the cellular network. With SNF
for Unreliable Mode enabled, if the Wi-Fi WAN connection is active and the cellular
connection is not (i.e. out of the cellular coverage area) reports continue to be sent over
Wi-Fi. Only if both networks are down are the reports stored and forwarded later when
either network is back up.
Note: You can also use an AT Command to set this value. For more information, see
*PPSNF on page 358.
