Note: By default, the advanced console server supports automatic failure-recovery back to the original state prior to failover (ﬁrmware

version 3.1.0 and later). The advanced console server continually pings probe addresses while in original and failover states. The original

state will automatically be set as a priority and reestablished following three successful pings of the probe addresses during failover. The

failover state will be removed once the original state has been re-established.

For earlier ﬁrmware that does not support automatic failure-recovery, restore networking to a recovered state by running the following

command:

rm -f /var/run/*-failed-over && conﬁg -r ipconﬁg

If required, you can run a custom bash script when the device fails over. It is possible to use this script to implement automatic failure

recovery, depending on your network setup. The script to create is:

/etc/conﬁg/scripts/interface-failover-alert

• You can check the connection status by selecting the Cellular panel on the Status: Statistics menu.

o The operational status will change as the cellular modem ﬁnds a channel and connects to the network.

o The Failover & Out-of-Band screen will display information relating to a conﬁgured Failover/OOB interface and the status

of that connection. The IP address of the Failover / OOB interface will be presented in the Failover & Out-of-Band screen

once the Failover/OOB interface has been triggered.

5.7.3 Cellular Routing

Once you have conﬁgured the carrier connection, the cellular modem can be conﬁgured to route trafﬁc through the console

server. This requires setting up forwarding and masquerading (refer to 5.8 Firewall and Forwarding).
