Debugging

6.Transit node receives a Ring-Up-Flush-FDB message.

The Health message from the previous step reaches the master node and shows it that all links in the ring are now up. The master node sends a Ring-Up-Flush-FDB message. When it receives the message, the transit node unblocks port 1 for vlan2, flushes its FDB, sends a trap, and changes the state to Link-Up.

This is the packet shown in step 10 on page 40 of the master node debug output.
