Mobile Broadband interfaces can be configured when a mobile broadband modem is available to the device. The Nodegrid SR family (NSR, GSR, BSR, LSR, HSR) support built-in modems available as optional add-ons. For all other units, external modems can be used.
The created interfaces allow the system to establish an Internet connection most used for failover options. Users and remote systems can directly access the device through a mobile connection (if supported by the ISP).
An APN (provided by the carrier) is required for all cellular connections. For more information on APNs, see https://support.zpesystems.com/portal/kb/articles/what-is-the-apn-for-my-nsr-or-bsr-to-connect-to-4g-lte
Go to Network :: Connections.
Click Add (displays dialog).
Enter Name.
On Type drop-down, select Mobile Broadband GSM (dialog changes).
On Interface drop-down, select one.
Enter Description.
If Connect Automatically checkbox is selected, connection is automatically established at startup.
Set as Primary Connection checkbox (defines interface as the primary connection. Only one interface can be the primary.)
If Enable LLDP advertising and reception through this connection checkbox is selected: On Port ID drop-down, select one. On Port Description drop-down, select one.
Select Block Unsolicited Incoming Packets checkbox (automatically blocks all inbound connections on the interface).
Select the Enable Connection Health Monitoring checkbox. When you enable this option:
A modem resets if the IP address is not reachable.
A modem power cycles if the reset fails.
Select Ensure Connection is Up checkbox
Enter IP Address
Enter Interval (hours) (default: 24)
Note:
The Connection Health Monitoring process works as follows:
When Connect Automatically is enabled (under Network :: Connections), the system first checks if the cellular connection is Up.
If the connection is Up, it verifies both the IP address and the health monitoring interval.
If the IP address is unreachable, the interface goes Down and comes Up again.
If the modem successfully obtains an IP address, it means that the modem is functional.
If the modem fails to connect:
The system attempts to reset the modem.
If the reset fails, the modem undergoes a power cycle.
