配置步骤
华为交换机：
在DeviceA和DeviceB上分别创建Eth-Trunk1并配置为手工模式。
# 配置DeviceA。
[HUAWEI] sysname DeviceA
[DeviceA] interface eth-trunk 1
[DeviceA-Eth-Trunk1] portswitch
[DeviceA-Eth-Trunk1] mode manual load-balance
# 配置DeviceB。
[HUAWEI] sysname DeviceB
[DeviceB] interface eth-trunk 1
[DeviceB-Eth-Trunk1] portswitch
[DeviceB-Eth-Trunk1] mode manual load-balance
向DeviceA和DeviceB的Eth-Trunk接口中加入成员接口。
# 配置DeviceA。
[DeviceA-Eth-Trunk1] trunkport 10ge 1/0/1 to 1/0/3
[DeviceA-Eth-Trunk1] quit
# 配置DeviceB。
[DeviceB-Eth-Trunk1] trunkport 10ge 1/0/1 to 1/0/3
[DeviceB-Eth-Trunk1] quit
在任意视图下执行display eth-trunk 1命令，检查Eth-Trunk是否创建成功，及成员接口是否正确加入。
[DeviceA] display eth-trunk 1
Eth-Trunk1's state information is:
Working Mode: Normal Hash Arithmetic: profile default
Least Active-linknumber: 1 Max Bandwidth-affected-linknumber: 128
Operating Status: up Number of Up Ports in Trunk: 3
--------------------------------------------------------------------------------
PortName Status Weight
10GE1/0/1 Up 1
10GE1/0/2 Up 1
10GE1/0/3 Up 1
从以上信息看出Eth-Trunk 1中包含3个成员接口10GE1/0/1、10GE1/0/2、10GE1/0/3，成员接口的状态都为Up。Eth-Trunk 1的“Operating Status”为Up
在DeviceA和DeviceB上分别创建Eth-Trunk1并配置为静态LACP模式。
# 配置DeviceA。
[HUAWEI] sysname DeviceA
[DeviceA] interface eth-trunk 1
[DeviceA-Eth-Trunk1] mode lacp-static
[DeviceA-Eth-Trunk1] quit
# 配置DeviceB。
[HUAWEI] sysname DeviceB
[DeviceB] interface eth-trunk 1
[DeviceB-Eth-Trunk1] mode lacp-static
[DeviceB-Eth-Trunk1] quit
向DeviceA和DeviceB的Eth-Trunk接口中加入成员接口。
# 配置DeviceA。
[DeviceA] interface 10ge 1/0/1
[DeviceA-10GE1/0/1] eth-trunk 1
[DeviceA-10GE1/0/1] quit
[DeviceA] interface 10ge 1/0/2
[DeviceA-10GE1/0/2] eth-trunk 1
[DeviceA-10GE1/0/2] quit
[DeviceA] interface 10ge 1/0/3
[DeviceA-10GE1/0/3] eth-trunk 1
[DeviceA-10GE1/0/3] quit
# 配置DeviceB。
[DeviceB] interface 10ge 1/0/1
[DeviceB-10GE1/0/1] eth-trunk 1
[DeviceB-10GE1/0/1] quit
[DeviceB] interface 10ge 1/0/2
[DeviceB-10GE1/0/2] eth-trunk 1
[DeviceB-10GE1/0/2] quit
[DeviceB] interface 10ge 1/0/3
[DeviceB-10GE1/0/3] eth-trunk 1
[DeviceB-10GE1/0/3] quit
华三交换机：
# 配置DeviceA。
采用静态聚合模式：创建二层聚合接口1
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] quit
采用动态聚合模式：创建二层聚合接口1，并配置动态聚合模式
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] link-aggregation mode dynamic
[DeviceA-Bridge-Aggregation1] quit
# 将端口Ten-GigabitEthernet1/0/1～Ten-GigabitEthernet1/0/3加入到聚合组1中。

[DeviceA-if-range] port link-aggregation group 1
[DeviceA-if-range] quit

# 通过display link-aggregation verbose命令来显示聚合组的相关信息，以验证配置是否成功。
采用静态聚合模式的链路聚合配置信息
[DeviceA] display link-aggregation verbose
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing
Port Status: S -- Selected, U -- Unselected, I -- Individual
Port: A -- Auto port, M -- Management port, R -- Reference port
Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,
D -- Synchronization, E -- Collecting, F -- Distributing,
G -- Defaulted, H -- Expired
Aggregation Interface: Bridge-Aggregation1
Aggregation Mode: Static
Loadsharing Type: Shar
Management VLANs: None
Port Status Priority Oper-Key
XGE1/0/1(R) S 32768 1
XGE1/0/2 S 32768 1
XGE1/0/3 S 32768 1
结果说明：本端加入到静态聚合组内的成员端口都处于Selected状态，与对端对应端口是否是Selected状态无关。

结果说明：本端和对端设备上聚合组内的成员端口都处于Selected状态。原因是在动态链路聚合中通过LACP协议报文交互，可使两端聚合组内的成员端口选中状态达成一致，可顺利实现对用户数据的转发。
