HostA能ping通HostB。
即使关闭了其中一个接口。
实验任务二：配置二层动态聚合
- 建立物理连接
- 基本配置
[SWA-Vlan-interface10]ip ad 192.168.0.1 24
[SWA]int rang ge 1/0/1 to ge 1/0/3
[SWA-if-range]port link-type trunk
[SWA-if-range]port trunk permit vlan 1 10
[SWA-Bridge-Aggregation1]port link-type trunk
[SWA-Bridge-Aggregation1]port trunk permit vlan 1 10
[SWA-Bridge-Aggregation1]link-aggregation mode dynamic//动态聚合模式
[SWA]int rang ge 1/0/1 to ge 1/0/3
[SWA-if-range]port link-aggregation group 1
[SWA-Bridge-Aggregation1]display link-aggregation verbose
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing
Port: A -- Auto
Port Status: S -- Selected, U -- Unselected, I -- Individual
Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,
D -- Synchronization, E -- Collecting, F -- Distributing,
G -- Defaulted, H -- Expired
Aggregate Interface: Bridge-Aggregation1
Aggregation Mode: Dynamic
Loadsharing Type: Shar

GE1/0/3 U 32768 1 {ACG}

Actor Partner Priority Oper-Key SystemID Flag
--------------------------------------------------------------------------------
GE1/0/1 0 32768 0 0x8000, 0000-0000-0000 {DEF}
GE1/0/2 0 32768 0 0x8000, 0000-0000-0000 {DEF}
GE1/0/3 0 32768 0 0x8000, 0000-0000-0000 {DEF}
在对端没有配置任何的情况下，动态聚合只能绑定一个端口。
对端进行和SWA同样的配置

GE1/0/3 4 32768 1 0x8000, ac53-b08d-0300 {ACDEF}
注：聚合端口配置不一致
- 第一类配置，例如MVRP,MSTP等，对链路汇聚没有影响
- 第二类配置，如端口隔离,Qinq配置，VLAN配置，MAC地址学习配置等配置不一样将不能成为Selected端口。
