There's something odd happenings here, and more than that was the solution of it.
We've a sharing with a Juniper MX80, and there're two 10G ports connect on, the 47 and 48 (Extreme).
After issuing the command:
configure sharing 47 add ports 45,46
The hashings seens to not work properly.
The traffic droped significantly, the two added ports (45,46) seems to be more affected than the 47,48.
Then comes the odd "solution", after disabling the sharing and adding again with the master becoming port 45, the problem was solved.
It's a problem to be checked, because it's the second time that I'm having the same problem.
I'm using the version 22.214.171.124 v1563b1-patch1-5.
