由於網絡交換機的每個端口在數據傳輸前都處於分離狀態,即使相連也只發生在發送和接收端口相連接時,因此交換機監控流量的過程較為複雜小.百.姓.网。
網絡交換機如何對網絡流量進行監控
● 端口鏡像(Port Mirroring): 交換機向網絡監控連接發送一組網絡數據包小+百+姓+网。
● SMON: RFC 2613中規定的「交換機監控」,是一種用來控制設施如「端口鏡像」的協議来自www.xbaixing.com。
另外還有些方法,在無需交換機的協作下,支持網絡中另一台計算機上的「Snooping」行為,如偽 ARP MAC 擴散行為小百姓网www.xbaixing.com。

How network switches monitor network traffic
● Port Mirroring: The switch sends a group of network data packets to the network monitoring connection.
● SMON: 'Switch monitoring' specified in RFC 2613 is a protocol used to control facilities such as 'port mirroring'.
There are also some methods that support 'Snooping' behavior on another computer in the network without the cooperation of a switch, such as pseudo ARP MAC diffusion behavior.
