Here is the API trace output from the CORE GUI for a two-node wired scenario.
{{{

# the first two NODE messages have the ADD flag set, instructing cored to create nodes n0 and n1
# the LINK message has the ADD flag set, and instructs cored to link together nodes n0 and n1; it creates interfaces eth0 on both nodes and assigns IPv4 and IPv6 addresses
# the two FILE messages tell cored to copy the _/tmp/core_n0.conf_ file to _/etc/quagga/Quagga.conf_ for node n0 and then for n1
# when the CORE GUI sends the first two NODE messages, it draws a red square around nodes n0 and n1 indicating to the user that the node startup is pending; when cored decides that the nodes have started, it replies back to the CORE GUI with a NODE message containing the emulation ID of the running node; the red square then turns green and disappears. These last two NODE messages perform that function.
Some time later, the user presses the *Stop* button on the CORE GUI. Here is the output from that event:
