Meaning
OK, Return path not tested (green
checkmark)
Displayed for a device which is reachable but which does not support the
feature to test the return path (device sending to this CEA-852 device).
Therefore a potential NAT router configuration error cannot be detected. If
the tested device is an L-IP, it is recommended to upgrade this L-IP to 3.0 or
higher.
Not reachable/not supported
(red exclamation)
This is displayed for the CS if it is not reachable or the CS does not support
this test. To remove this uncertainty it is recommended to upgrade the L-IP to
3.0 or higher.
Local NAT config. Error
(red exclamation)
This is displayed if the CEA-852 device of the L-DALI is located behind a
NAT router or firewall, and the port-forwarding in the NAT-Router (usually
1628) or the filter table of the firewall is incorrect.
Peer not reachable
(red exclamation)
Displayed for a device, if it is not reachable. No RTT is displayed. The device
is either not online, not connected to the network, has no IP address, or is not
reachable behind its NAT router. Execute this test on the suspicious device to
determine any NAT configuration problem.

5.5.7 Global Connections Statistics
The global connections statistics page shows all currently configured communication
groups. For each group the list displays name, address hash, receive, transmit, poll-on-
startup status, the most recently communicated value and its timestamp. An example is
shown in Figure 104. The receive/transmit/poll-on-startup status displays an
if the
direction is configured, but no value was communicated. A green check mark is shown as
soon as a value was received or transmitted, respectively.
