I don't get it how this works?
I guess you mine X11 or X13 algo coin with the same miner and pool switch between them. In that case, why we need two different ports?
Maybe when X13 is more profitable then just the 4011 port is active, and when X11 becomes more profitable, the 4011 port switches off, the 4010 port switches on, your miner reports "connection interrupted" and switches to the 4010 port using failover. And back to X13 using the same procedure (when X13 becomes more profitable again).
