要求聚合的端口工作在全双工，速度一致，在同一槽口且连续。
参数：ingress:源MAC,both:源和目的MAC
参数：ingress:源MAC,both:源和目的MAC
对于SwitchA:
[SwitchA]interface ethernet0/1
[SwitchA-Ethernet0/1]duplex full ＃设置以太口全双工状态
[SwitchA-Ethernet0/1]speed 100
[SwitchA-Ethernet0/1]mdi across＃(连接网线为交叉网线）/normal ＃为连接网线类型为平行网线．
[SwitchA-Ethernet0/1]flow_control #开启流量控制
[SwitchA-Ethernet0/1]broadcast_suppression 10 #广播风暴仰制比
[SwitchA-Ethernet0/1]port link_type access ＃端口连接类型
[SwitchA-Ethernet0/1]int e0/2
[SwitchA-Ethernet0/2]duplex full
[SwitchA-Ethernet0/2]speed 100
[SwitchA-Ethernet0/2]duplex full
[SwitchA-Ethernet0/2]speed 100
对于SwitchB:
[SwitchB]interface ethernet0/1
[SwitchB-Ethernet0/1]duplex full
[SwitchB-Ethernet0/1]speed 100
[SwitchB-Ethernet0/1]duplex full
[SwitchB-Ethernet0/1]speed 100
[SwitchB-Ethernet0/1]int e0/2
[SwitchB-Ethernet0/2]duplex full
[SwitchB-Ethernet0/2]speed 100
[SwitchB-Ethernet0/2]duplex full
[SwitchB-Ethernet0/2]speed 100
聚合操作：
[SwitchA]link-aggregation ethernet0/1 to ethernet0/2 both
[SwitchB]link-aggregation ethernet0/1 to ethernet0/2 both
[SwitchB]link-aggregation ethernet0/1 to ethernet0/2 both
[SwitchA]display link-aggregation ethernet0/1 [SwitchA]undo link-aggregation all
