What is the notice matters for S9300 flow control cofiguration?
1）、S9300 flow control is divided to broadcast flow control ， multicast flow control and unknown unicast flow control，their flow control realization is same.
2）、S9300 flow control contains 3 kinds of mode：Flow control base packet rete. Flow control base bit rate.Flow control base percent.
Broadcast flow was flow controlled base 50% packet rete by default, Broadcast flow and unknow unicast do not enable control function defautly.
3）、Control function under ports is corresponded for one kind of packet，Open ports broadcast packet control function，only make broadcast packet control. Open ports multicast packet control function，only make multicast packet control . Open ports unknow unicast packet control function，only make unknow unicast packet control , it can configure 3 kinds of control at the same time.
4）、The same interface cannot configure flow control base packet and bit. For instance, some interface has configured multicast flow control base bit, it cannot configure broadcast flow control base packet rate
5）、It only supports ports lever flow control, and it only supports make flow control on inbound interface.
