Eth-Trunk

例：配置三层链路聚合

组网需求

如图所示，DeviceA和DeviceB之间创建Eth-Trunk，将两个三层以太网接口捆绑成一个Eth-Trunk接口，可以增加带宽和提高可靠性。

注意：本例中interface1、interface2分别代表10GE0/0/1、10GE0/0/2。

图1-2 配置三层链路聚合组网图

操作步骤

在DeviceA和DeviceB上分别创建Eth-Trunk1并配置IP地址。

# 配置DeviceA。
```
<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] interface eth-trunk 1
[DeviceA-Eth-Trunk1] undo portswitch
[DeviceA-Eth-Trunk1] ip address 10.1.1.1 24
```
# 配置DeviceB。

<HUAWEI> system-view [HUAWEI] sysname DeviceB [DeviceB] interface eth-trunk 1 [DeviceB-Eth-Trunk1] undo portswitch [DeviceB-Eth-Trunk1] ip address 10.1.1.2 24

向DeviceA和DeviceB的Eth-Trunk接口中加入成员接口。

# 配置DeviceA。

[DeviceB] interface eth-trunk 1
[DeviceA-Eth-Trunk1] port link-type trunk
[DeviceA-Eth-Trunk1] trunkport 10ge 0/0/1 to 0/0/2 
[DeviceA-Eth-Trunk1] quit

# 配置DeviceB。

[DeviceB] interface eth-trunk 1
[DeviceB-Eth-Trunk1] port link-type trunk
[DeviceB-Eth-Trunk1] trunkport 10ge 0/0/1 to 0/0/2 
[DeviceB-Eth-Trunk1] quit

检查配置结果

# 在任意视图下执行display interface eth-trunk命令，检查Eth-Trunk是否创建成功，及成员接口是否正确加入。

VLAN

举例：配置基于接口划分VLAN，实现同一VLAN内的互通（同设备）

组网需求

如图1-2所示，把连接Host1和Host2的接口划分到VLAN2，把连接Host3和Host4的接口划分到VLAN3，实现同一VLAN内的主机可以通信，不同VLAN内的主机不能直接二层通信。

Host1和Host2可以互相通信，Host3和Host4可以互相通信。
Host1和VLAN3内的Host3、Host4不能互相通信，Host2和VLAN3内的Host3、Host4不能互相通信。

图1-2 基于接口划分VLAN组网图（同设备）

注意：本例中interface1、interface2、interface3、interface4分别代表10GE0/0/1、10GE0/0/2、10GE0/0/3、10GE0/0/4。

操作步骤

创建VLAN，并配置设备与主机相连的接口为Access类型接口。

<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] vlan batch 2 3
[DeviceA] interface 10ge 0/0/1
[DeviceA-10GE0/0/1] portswitch
[DeviceA-10GE0/0/1] port link-type access
[DeviceA-10GE0/0/1] quit
[DeviceA] interface 10ge 0/0/2
[DeviceA-10GE0/0/2] portswitch
[DeviceA-10GE0/0/2] port link-type access
[DeviceA-10GE0/0/2] quit
[DeviceA] interface 10ge 0/0/3
[DeviceA-10GE0/0/3] portswitch
[DeviceA-10GE0/0/3] port link-type access
[DeviceA-10GE0/0/3] quit
[DeviceA] interface 10ge 0/0/4
[DeviceA-10GE0/0/4] portswitch
[DeviceA-10GE0/0/4] port link-type access
[DeviceA-10GE0/0/4] quit

配置接口加入VLAN。

# 将10GE0/0/1和10GE0/0/2接口加入VLAN2。

[DeviceA] vlan 2
[DeviceA-vlan2] port 10ge 0/0/1 to 0/0/2
[DeviceA-vlan2] quit

# 将10GE0/0/3和10GE0/0/4接口加入VLAN3。

[DeviceA] vlan 3
[DeviceA-vlan3] port 10ge 0/0/3 to 0/0/4
[DeviceA-vlan3] quit

检查配置结果

# 执行display vlan命令可以查看VLAN状态。

举例：配置三层子接口实现不同VLAN间的互通

组网需求

如图1-3所示，VLAN2内的主机和VLAN3内的主机位于不同的网段。希望在DeviceA上配置三层子接口，实现VLAN2与VLAN3之间的主机互通。

图1-3 通过三层子接口实现不同VLAN间的互通组网图

注意：本例中interface1、interface2、interface3、interface4分别代表10GE0/0/1、10GE0/0/2、10GE0/0/3、10GE0/0/4。

操作步骤

在DeviceB上创建VLAN。

<HUAWEI> system-view
[HUAWEI] sysname DeviceB
[DeviceB] vlan batch 2 3
[DeviceB] interface 10ge 0/0/1
[DeviceB-10GE0/0/1] portswitch
[DeviceB-10GE0/0/1] port link-type access
[DeviceB-10GE0/0/1] port default vlan 2
[DeviceB-10GE0/0/1] quit
[DeviceB] interface 10ge 0/0/2
[DeviceB-10GE0/0/2] portswitch
[DeviceB-10GE0/0/2] port link-type access
[DeviceB-10GE0/0/2] port default vlan 3
[DeviceB-10GE0/0/2] quit

在DeviceB的接口10GE0/0/3上配置允许用户所属的VLAN通过。

[DeviceB] interface 10ge 0/0/3
[DeviceB-10GE0/0/3] portswitch
[DeviceB-10GE0/0/3] port link-type trunk
[DeviceB-10GE0/0/3] port trunk allow-pass vlan 2 3
[DeviceB-10GE0/0/3] quit

在DeviceA上创建子接口并关联VLAN。

<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] interface 10ge 0/0/4
[DeviceA-10GE0/0/4] undo portswitch
[DeviceA-10GE0/0/4] quit
[DeviceA] interface 10ge 0/0/4.1
[DeviceA-10GE0/0/4.1] dot1q termination vid 2 
[DeviceA-10GE0/0/4.1] quit
[DeviceA] interface 10ge 0/0/4.2
[DeviceA-10GE0/0/4.2] dot1q termination vid 3
[DeviceA-10GE0/0/4.2] quit

在DeviceA上配置IP地址。

[DeviceA] interface 10ge 0/0/4.1
[DeviceA-10GE0/0/4.1] ip address 10.10.10.2 24
[DeviceA-10GE0/0/4.1] quit
[DeviceA] interface 10ge 0/0/4.2
[DeviceA-10GE0/0/4.2] ip address 10.10.20.2 24
[DeviceA-10GE0/0/4.2] quit

检查配置结果

在VLAN2的主机上配置缺省网关为接口10GE0/0/4.1的IP地址10.10.10.2/24，在VLAN3的主机上配置缺省网关为接口10GE0/0/4.2的IP地址10.10.20.2/24。配置完成后，VLAN2和VLAN3之间的主机能够相互Ping通。

举例：配置VLANIF接口实现不同VLAN间的互通（同设备）

组网需求

如图1-4所示，DeviceA下的主机被划分到不同的VLAN中，分别是VLAN2和VLAN3，且位于不同的网段。希望实现VLAN2和VLAN3之间相互通信。

图1-4 配置VLANIF接口实现不同VLAN间的互通组网图（同设备）

注意：本例中interface1、interface2分别代表10GE0/0/1、10GE0/0/2。

操作步骤

创建VLAN，并配置接口加入VLAN。

<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] vlan batch 2 3
[DeviceA] interface 10ge 0/0/1
[DeviceA-10GE0/0/1] portswitch
[DeviceA-10GE0/0/1] port link-type access
[DeviceA-10GE0/0/1] port default vlan 2
[DeviceA-10GE0/0/1] quit
[DeviceA] interface 10ge 0/0/2
[DeviceA-10GE0/0/2] portswitch
[DeviceA-10GE0/0/2] port link-type access
[DeviceA-10GE0/0/2] port default vlan 3
[DeviceA-10GE0/0/2] quit

配置VLANIF接口的IP地址。

[DeviceA] interface vlanif 2
[DeviceA-Vlanif2] ip address 10.10.10.2 24
[DeviceA-Vlanif2] quit
[DeviceA] interface vlanif 3
[DeviceA-Vlanif3] ip address 10.10.20.2 24
[DeviceA-Vlanif3] quit

检查配置结果

在VLAN2中的主机上配置IP地址为10.10.10.1/24，缺省网关为接口VLANIF2的IP地址10.10.10.2/24，在VLAN3中的主机上配置IP地址为10.10.20.1/24，缺省网关为接口VLANIF3的IP地址10.10.20.2/24。配置完成后，VLAN2中的主机与VLAN3中的主机能够相互Ping通。
