help bug to 6.27

report a bug version 6.27 RB450G create the master port and then hangs I do not know anyone like him how to solve it?

Thanks for reporting, I will check this

I did not find any bug here, the board actually doesn’t hang, the problem was because when you set for example:

ether 1 (mac 00:0C:42:53:14:08) masterport=ether2 (mac 00:0C:42:53:14:09)

while connected to ether1, connection switches from ether1 mac to ether2 mac, and you should simply reconnect board with master port mac.

You should not experience anything similar while connected, for example, ether 3-ether5

please have a look at Ticket#2015010766000601
the issue is happening form v 5.24 but still no solution
even i was so irritated that i assumed you will never be helping me out of this
