Debugging

Link Down Between Two Transit Nodes

This section shows the debugging output when the link between transit node B and transit node C goes down and comes back up again. It shows the debugging output for the complete failure and recovery cycle:

on the master node, and then

on transit node B

Master Node (Node A) Debug Output

The following debugging output starts with the ring established and in a state of Complete.

1.The master node sends Health messages

Each time the Hello timer expires, the master node sends a Health message out its primary port (port 1). As long as the ring is in a state of Complete, it receives each Health message again on its secondary port (port 2).
