那么,為什么需要分割廣播域呢?那是因為,如果僅有一個廣播域,有可能會影響到網絡整體的傳輸性能。具體原因,請參看附圖加深理解。

交換機1收到廣播幀(ARP請求)后,會將它轉發給除接收端口外的其他所有端口,也就是Flooding了。接著,交換機2收到廣播幀后也會Flooding。交換機3、4、5也還會Flooding。最終ARP請求會被轉發到同一網絡中的所有客戶機上。

                實現VLAN的機制

zailijiele“weishenmexuyaovlan”zhihou,jiexialairangwomenlailejieyixiajiaohuanjishiruheshiyongvlanfengeguangboyude。


首先,在一臺未設置任何VLAN的二層交換機上,任何廣播幀都會被轉發給除接收端口外的所有其他端口(Flooding)。例如,計算機A發送廣播信息后,會被轉發給端口2、3、4。






這時,如果在交換機上生成紅、藍兩個VLAN;同時設置端口1、2屬于紅色VLAN、端口3、4屬于藍色VLAN。再從A發出廣播幀的話,交換機就只會把它轉發給同屬于一個VLAN的其他端口——也就是同屬于紅色VLAN的端口2,不會再轉發給屬于藍色VLAN的端口。

如果要更為直觀地描述VLAN的話,我們可以把它理解為將一臺交換機在邏輯上分割成了數臺交換機。在一臺交換機上生成紅、藍兩個VLAN,也可以看作是將一臺交換機換做一紅一藍兩臺虛擬的交換機。

由于需要一個個端口地指定,因此當網絡中的計算機數目超過一定數字(比如數百臺)后,設定操作就會變得煩雜無比。并且,客戶機每次變更所連端口,都必須同時更改該端口所屬VLAN的設定——這顯然不適合那些需要頻繁改變拓補結構的網絡。

基于MAC地址的VLAN,就是通過查詢并記錄端口所連計算機上網卡的MAC地址來決定端口的所屬。假定有一個MAC地址“A”被交換機設定為屬于VLAN“10”,那么不論MAC地址為“A”的這臺計算機連在交換機哪個端口,該端口都會被劃分到VLAN10中去。計算機連在端口1時,端口1屬于VLAN10;而計算機連在端口2時,則是端口2屬于VLAN10。

基于子網的VLAN,則是通過所連計算機的IP地址,來決定端口所屬VLAN的。不像基于MAC地址的VLAN,即使計算機因為交換了網卡或是其他原因導致MAC地址改變,只要它的IP地址不變,就仍可以加入原先設定的VLAN。

在規劃企業級網絡時,很有可能會遇到隸屬于同一部門的用戶分散在同一座建筑物中的不同樓層的情況,這時可能就需要考慮到如何跨越多臺交換機設置VLAN的問題了。假設有如下圖所示的網絡,且需要將不同樓層的A、C和B、D設置為同一個VLAN。

交換機2收到數據幀后,經過檢查VLAN標識發現這個數據幀是屬于紅色VLAN的,因此去除標記后根據需要將復原的數據幀只轉發給其他屬于紅色VLAN的端口。這時的轉送,是指經過確認目標MAC地址并與MAC地址列表比對后只轉發給目標MAC地址所連的端口。只有當數據幀是一個廣播幀、多播幀或是目標不明的幀時,它才會被轉發到所有屬于紅色VLAN的端口。
