This document describes how to configure link monitoring (sometimes called line polling) for IPoE-based Internet connections.

Info
As of LCOS version 8.80, link monitoring can be setup directly when configuring an IPoE-based Internet connection in the Setup Wizard. With LCOS versions before version 8.80, link monitoring must be set up manually in the configuration.
1) Configuring link monitoring in the Setup Wizard (as of LCOS 8.80):
1.1) In LANconfig, start
the
the Setup Wizardfor setting up Internet access.
1.2) Follow the wizard's instructions until the dialog where you can
configure
configure link monitoring for the Internet connection.
With the option Link monitoring by pinging the DNS server, pings are sent to the public IP address of the DNS serveras specified in the connection parameters of the IPoE connection (i.e. ICMP packets are sent periodically).
With the option Link monitoring by pinging own IP addresses, a subsequent dialog allows you to specify up to four public IP addresses, which can be pinged for line monitoring.

menu Configuration -> Communication ->
menu Communication → Remote sites

In the field Remote site, enter the Internet connection, for which the line monitoring should be performed.
In the fields IP address xyou need to specify at least one public IP address, which should be pinged for line monitoring.
If you fill in the fields Ping intervaland Retrieswith the value 0(default), an interval of 20 seconds for 5 retriesis taken. This default setting is sufficient for most applications.
