Debugging
Transit Node (Node B) Debug Output
The following debugging shows the same events as the previous section, but on the transit
node instead of the master node. It starts with the ring established and in a state of
Complete.
The transit node receives Health messages on port 1, because that port is connected to the
master node’s primary port. Note that the message shows that the ring state is Complete.
This is the packet shown in step 1 on page 47 of the master node debug output.
The transit node receives Health message 328. At this stage, the message does not indicate
that anything is wrong. However, between messages 327 and 328, the link went down. This
means that message 328 will not make it back to the master node.
This is the packet shown in step 2 on page 48 of the master node debug output.
1. The transit node receives Health messages
