怎么把两个端口配置成一个聚合口？

1.13.1  二层静态聚合配置举例

1. 组网需求

·     Device A与Device B通过各自的二层以太网接口Ten-GigabitEthernet1/0/1～Ten-GigabitEthernet1/0/3相互连接。

·     在Device A和Device B上分别配置二层静态链路聚合组，并实现设备间VLAN 10和VLAN 20分别互通。

2. 组网图

3. 配置步骤

(1)     配置Device A

# 创建VLAN 10，并将端口Ten-GigabitEthernet1/0/4加入到该VLAN中。

<DeviceA> system-view

[DeviceA] vlan 10

[DeviceA-vlan10] port ten-gigabitethernet 1/0/4

[DeviceA-vlan10] quit

# 创建VLAN 20，并将端口Ten-GigabitEthernet1/0/5加入到该VLAN中。

[DeviceA] vlan 20

[DeviceA-vlan20] port ten-gigabitethernet 1/0/5

[DeviceA-vlan20] quit

# 创建二层聚合接口1。

[DeviceA] interface bridge-aggregation 1

[DeviceA-Bridge-Aggregation1] quit

# 分别将端口Ten-GigabitEthernet1/0/1至Ten-GigabitEthernet1/0/3加入到聚合组1中。

[DeviceA] interface ten-gigabitethernet 1/0/1

[DeviceA-Ten-GigabitEthernet1/0/1] port link-aggregation group 1

[DeviceA-Ten-GigabitEthernet1/0/1] quit

[DeviceA] interface ten-gigabitethernet 1/0/2

[DeviceA-Ten-GigabitEthernet1/0/2] port link-aggregation group 1

[DeviceA-Ten-GigabitEthernet1/0/2] quit

[DeviceA] interface ten-gigabitethernet 1/0/3

[DeviceA-Ten-GigabitEthernet1/0/3] port link-aggregation group 1

[DeviceA-Ten-GigabitEthernet1/0/3] quit

# 配置二层聚合接口1为Trunk端口，并允许VLAN 10和20的报文通过。

[DeviceA] interface bridge-aggregation 1

[DeviceA-Bridge-Aggregation1] port link-type trunk

[DeviceA-Bridge-Aggregation1] port trunk permit vlan 10 20

[DeviceA-Bridge-Aggregation1] quit

(2)     配置Device B

Device B的配置与Device A相似，配置过程略。

4. 验证配置

# 查看Device A上所有聚合组的详细信息。

[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

Aggregate Interface: Bridge-Aggregation1

Aggregation Mode: Static

Loadsharing Type: NonS

Management VLANs: None

  Port             Status  Priority Oper-Key

  XGE1/0/1         S       32768    1

  XGE1/0/2         S       32768    1

  XGE1/0/3         S       32768    1

以上信息表明，聚合组1为非负载分担类型的二层静态聚合组，包含有三个选中端口。
