Hello.
I got a problems when configuring LACP with Linux machine now. That is a R515 with Intel Corporation 82599EB 10-Gigabit SFP interfaces. And then connected to 2 stacking 8132F switch respectively. ie. SFP port 1 connected to first 8132F and then port 2 connected to 2nd 8132F.
It strange now is sometimes could not connect those machines but sometimes can. Sometimes bond0 is connect but bond0.20 is cann't. Also, some file transfer test result showing only 10G (I expect is more then 10G) bandwidth can make.
It already changed many different configs but no luck. Please advise about this. The following is those configuration for reference.
Additional what is the relationship between Switch Hash Configuration and xmit_hash_policy under linux? is it they need match it?
