The Connect EZ device is now configured to use the cellular modem WWAN,
Modem
, as its highest
priority WAN, and its Ethernet WAN,
ETH1
, as its secondary WAN.
Configure SureLink active recovery to detect WAN failures
Problems can occur beyond the immediate WAN connection that prevent some IP traffic from
reaching its destination. Normally this kind of problem does not cause the Connect EZ device to
detect that the WAN has failed, because the connection continues to work while the core problem
exists somewhere else in the network.
Using Digi SureLink, you can configure the Connect EZ device to regularly probe connections through
the WAN to determine if the WAN has failed.
Required configuration items
n
Enable SureLink. SureLink can be enabled for both IPv4 and IPv6 configurations. By default,
SureLink is enabled for IPv4 for the preconfigured WAN. It is disabled for IPv6.
n
The type of probe test to be performed, one of:
l
Test another interface's status: Used to create a failover or coupled relationship between
two interfaces. Requires the name of the alternate interface, the IP version to be tested,
and the expected status of the alternate interface (either up or down).
l
Ping: Requires the hostname or IP address of the host to be pinged.
l
DNS query: You can perform a DNS query to a named DNS server, or to the DNS servers
configured for the WAN.
l
HTTP test: Requires the URL of the host to be tested.
l
Test DNS servers configured for this interface: Tests communication with this interface's
DNS servers that are either provided by DHCP, or statically configured.
