目標是把兩個Port bonding起來使用LACP(802.3ad)，並在Bonding Port上跑多個VLAN。
步驟一：建立bonding port
到System -> Network -> Create -> Linux bond
Name : 第一個bonding port就取名為bond0
Slaves : 輸入要加入的網卡名稱
Mode : 這邊要配合Switch設定，這邊就是配合範例使用LACP
Hash policy : 分流的演算法，Layer2+3通常不錯
這步驟實際上應該先選一個網卡，因為目前連上PVE的網卡是被占用，可以建立好bond0後，確定可以連現在把舊的vmbr0給刪除。
步驟二：建立Linux Bridge
到System -> Network -> Create -> Linux Bridge
這邊取名為vmbr1，避免和原來vmbr0的衝突到，Bridge ports輸入步驟一的bond0，VLAN aware要打勾，意思是要不要帶VLAN Tag。
步驟三：建立Linux VLAN
到System -> Network -> Create -> Linux VLAN，名稱輸入步驟二命名的vmbr1.vlanid，如下我要建立一個Vlan ID是16的Vlan，所以輸入vmbr1.16，MTU如果有Storage網段可以考慮設定9000。
步驟四：點選Apply Configuration
Network都新增完後，點選Apply Configuration。
刪掉vmbr0後，完整的結果會長如下圖的樣子。
步驟五：設定Switch LACP
這邊就看各家Switch如何設定，Switch那邊的LACP要匹配步驟一的模式，也就是Active，然後VLAN要帶入與步驟三設定的Tag ID。
步驟六：驗證LACP是否成功
在PVE Shell輸入下面指令查看bond0狀態。

這邊就是直接用步驟三設定好的Vlan IP去ping同網段的IP就知道有沒有成功。
