[FineConnection web site]You can verify whether your map is "EC proof" by enabling EC and after that clicking the 
speedbutton on the Monitor one control panel.
Example 1.
A small company has two offices in different cities connected by internet via ADSL. The Firewall in the main office has a problem and is down. As you can see from the screenshot, EC is enabled (the "ThisStation" object is present on the map) but nevertheless all devices in the remote office have been marked "down" (erroneously)!
In the above case, the problem is caused by not checking the "This device forwards traffic…." checkbox for the Class the device "InternetCloud" belongs to. As a result, Monitor one "thinks" that it cannot reach the remote office devices at the other end of the WAN link. Monitor one "thinks" that there are no network paths available from the "ThisStation" object to the devices in the remote offices and displays the little "network disconnected" symbols at the bottom left of each device in the remote office. The "InternetCloud" device represents the huge internet routing network in one device.
After checking the "This device forwards traffic……" checkbox for the Class the "InternetCloud" device belongs to, the network map shows:
Example 2.
The screenshot above shows another interesting example. For reasons of redundancy, a cluster system has two connections to two different switches. Only the first NIC is active, the second one is "Hot-standby". By mistake, the "Forward" setting of the Class the device "Cluster1" belongs to is checked. Switch4 is actually down! Because of the "forward" setting of Cluster1, Monitor one "thinks" that there is an alternate network path to device Switch3, gets no reply from device Switch3 and marks it accordingly.
After clicking the EC verifier speedbutton on the Monitor one control panel, the map shows:
Only TestServer1 has the "No Error Control information available" indicator (it is not connected).
After resetting the "Forward" control (unchecking the checkbox) of the Class the device Cluster1 belongs to, the map shows:
