Debugging
Now that the ring is back up, the master node blocks its secondary port for the data VLAN,
transmits a Ring-Up-Flush-FDB message, flushes its FDB, sends a trap, and changes the EPSR
state to Complete.
The master node receives the Ring-Up-Flush-FDB message back on its secondary port,
because the packet traversed the whole ring. The master node ignores the message.
8. The master node returns the ring to a state of Complete
