配置思路
二層鏈路靜態(tài)聚合(link aggregation)配置
本實驗中，s5130交換機上聯(lián)為DMZ_S5120和NW_S5500交換機
NW側的二層聚合接口為BAG13
要使去往NW的VLAN10與VLAN20的數據流量均能通過二層聚合接口13，須配置二層聚合接口的鏈路類型為Trunk端口，并允許VLAN10和VLAN20的報文通過。
DMZ側的二層聚合接口為BAG26
要使去往DMZ的VLAN110與VLAN120的數據流量均能通過二層聚合接口26，須配置二層聚合接口的鏈路類型為Trunk端口，并允許VLAN110和VLAN120的報文通過。
配置注意事項
先配置二層鏈路聚合接口組，退出配置進入對應端口(所有需要加入的端口)依次加入聚合組，再次進入聚合組進行vlan放行，否則端口無法自動識別聚合組內vlan信息
