华三&华为链路聚合配置案例

华为：

在DeviceA和DeviceB上分别创建Eth-Trunk1并配置为手工模式。

# 配置DeviceA。

<HUAWEI> system-view

[HUAWEI] sysname DeviceA

[DeviceA] interface eth-trunk 1

[DeviceA-Eth-Trunk1] portswitch

[DeviceA-Eth-Trunk1] mode manual load-balance

# 配置DeviceB。

<HUAWEI> system-view

[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> system-view

[HUAWEI] sysname DeviceA

[DeviceA] interface eth-trunk 1

[DeviceA-Eth-Trunk1] mode lacp-static

[DeviceA-Eth-Trunk1] quit

# 配置DeviceB。

 

<HUAWEI> system-view

[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

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

# 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

  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。
