Monitors are used to detect and try to recover from "high level" communication failures occurring on a healthy connection between a WAN link and the carrier network. For example, when the MG90 is out of range of the carrier network but the connection is not dropped, the link cannot pass traffic.
A monitor accomplishes detection and recovery by periodically checking against its preconfigured parameters for problems such as a minimum number of connection failures, timeouts, etc.
TIP: Sierra Wireless strongly recommends that one or more monitors be created and configured for cellular devices.
Creating or modifying monitors
To create or modify a monitor:
Go to WAN > Monitors.
Click Add New WAN Monitor to create a new monitor, or click Configure in the Actions column to modify an existing monitor.
Modify the monitor settings as required to detect a connection that can no longer pass traffic, and ensure the correct Source Address is selected (Monitored Link IP for link monitoring, or the source LAN segment address for VPN monitoring).
Click Save
Enabling monitors on WAN links
To use monitors on a Cellular or Ethernet link, enable them in the link details:
Go to WAN > Links.
Click Configure in the Actions column for the link.
Select the desired monitor(s) in the Monitors list. (Note—More than one monitor can be selected.)
Click Save.
To use monitors on a Wi-Fi link, enable them in the Wi-Fi networks (AP profiles) selected in the link:
Check which Wi-Fi networks can be used by the Wi-Fi link:
a. Go to WAN > Links.
b. Click Configure in the Actions column for the link.
c. Make note of the Wi-Fi networks that are selected.
2. Go to WAN > Wi-Fi Networks.
3. For each Wi-Fi network that will have monitors added:
a. Click Configure in the Actions column for the desired network.
b. In the Network Settings area, select the desired monitor(s) in the Monitors list.
(Note—You can select more than one monitor.)
c. Click Save.
Deleting monitors
To delete a monitor:
Go to WAN > Monitors.
Click Delete in the Actions column for the monitor to delete.
Click OK when prompted to confirm the deletion.
