2.Port 1 on the transit node goes down
The transit node detects that port 1 (between the transit node and the master node) has gone down. The transit node flushes its forwarding database, blocks port 1 for the data VLAN (to prevent a loop from forming when the master node comes back up), sends a Link- Down message towards the master node, sends a trap, and changes the EPSR state to Link- Down.
This is the packet shown in step 4 on page 38 of the master node debug output.
