CM210Q-W Router User Manual
ICMP Check and Cellular Traffic Check are different.
【
ICMP Check
】
If you enable ICMP, the router will automatically check whether the defined IP
address is reachable every 60s. If the IP address is unreachable and the ICMP
check fails the first time, it will check twice again at a 3s interval. If the ICMP
check fails the third time, the router will implement the “fail action” as
configured.
The Check IP is a public IP or a company server IP address.
【
Cellular Traffic Check
】
【
Check Mode
】
there are three modes, Rx(Receive), Tx(Transmit) and Rx/Tx
check modes.
【
Rx
】
The router will check the 3G/LTE cellular traffic received. If no traffic is
received within the defined check interval time, the router will implement the “fail
action” selected, cellular reconnect or reboot.
【
SIM Mode
】
【
Fail Over
】
When SIM 1 fails, the router will switch to SIM 2. When SIM 2
fails, the router will switch back to SIM 1.
【
SIM1 Only
】
Just SIM1 is available.
【
SIM2 Only
】
Just SIM2 is available.
【
Backup
】
SIM1 is the primary SIM. When SIM 1 fails, the router will switch
to SIM 2 and stays on SIM 2 for a set period at the end of which it will switch
back to SIM 1.
