链路聚合ET-TRUNK配置实例

路由器配置实例

路由器可以对多个以太网接口捆绑形成一个Eth-Trunk逻辑接口，Eth-Trunk接口的主要目的是增大带宽和提高设备之间链路的可靠性。Eth-Trunk接口可以工作在二层模式或三层模式。二层模式的Eth-Trunk接口类似交互机的接口，只负责二层数据包的转发；三层模式的Eth-Trunk 接口则类似路由器的接口，可以配上IP地址实现路由功能。本文为大家介绍如何在华为的路由器里配置二层和三层Eth-Trunk接口。

一、二层Eth-Trunk接口配置实例

1、组网结构和需求

如下图所示，RouterA和RouterB之间通过Eth-Trunk1连接，Eth-Trunk1是二层端口。将Eth-Trunk1配置为Trunk类型接口，允许RouterA和RouterB之间的所有VLAN帧通过。

2、配置思路

采用如下的思路配置二层Eth-Trunk端口允许VLAN通过：

1）创建Eth-Trunk接口。

2）将Eth-Trunk接口转为二层端口。

3）将Eth-Trunk端口配置为Trunk类型的端口，并允许所有VLAN帧通过。

4）将成员口接入Eth-Trunk端口中。

3、配置步骤

1）配置RouterA

# 创建Eth-Trunk接口，并配置允许通过的VLAN。

[RouterA] interface eth-trunk 1

[RouterA-Eth-Trunk1] portswitch

[RouterA-Eth-Trunk1] port link-type trunk

[RouterA-Eth-Trunk1] port trunk allow-pass vlan all

[RouterA-Eth-Trunk1] quit

# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。

[RouterA] interface gigabitethernet 1/0/0

[RouterA-GigabitEthernet1/0/0] undo shutdown

[RouterA-GigabitEthernet1/0/0] eth-trunk 1

[RouterA-GigabitEthernet1/0/0] quit

[RouterA] interface gigabitethernet 2/0/0

[RouterA-GigabitEthernet2/0/0] undo shutdown

[RouterA-GigabitEthernet2/0/0] eth-trunk 1

[RouterA-GigabitEthernet2/0/0] quit

2）配置RouterB

# 创建Eth-Trunk接口，并配置允许通过的VLAN。

[RouterB] interface eth-trunk 1

[RouterB-Eth-Trunk1] portswitch

[RouterB-Eth-Trunk1] port link-type trunk

[RouterB-Eth-Trunk1] port trunk allow-pass vlan all

[RouterB-Eth-Trunk1] quit

# 将接口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。

[RouterB] interface gigabitethernet 1/0/0

[RouterB-GigabitEthernet1/0/0] undo shutdown

[RouterB-GigabitEthernet1/0/0] eth-trunk 1

[RouterB-GigabitEthernet1/0/0] quit

[RouterB] interface gigabitethernet 2/0/0

[RouterB-GigabitEthernet2/0/0] undo shutdown

[RouterB-GigabitEthernet2/0/0] eth-trunk 1

[RouterB-GigabitEthernet2/0/0] quit

4、验证配置结果

查看Eth-Trunk1的状态，以RouterA为例：

display trunkmembership eth-trunk 1

Trunk ID: 1

used status: VALID

TYPE: ethernet

Working Mode : Normal

Working State: Normal

Number Of Ports in Trunk = 2

Number Of UP Ports in Trunk = 2

operate status: up

Interface Ethernet1/0/0, valid, selected, operate up, weight=1,

standby interface NULL

Interface Ethernet2/0/0, valid, selected, operate up, weight=1,

standby interface NULL

用display port vlan命令查看Eth-Trunk端口上可以通过的VLAN信息。以RouterA为例： display port vlan Eth-Trunk 1

Port Link Type PVID Trunk VLAN List

-------------------------------------------------------------------------------

Eth-Trunk1 trunk 0 1-4094

5、配置文件

1）RouterA的配置文件

#

sysname RouterA

#

interface Eth-Trunk1

portswitch

port link-type trunk
