应用环境
Trunk将多个端口聚合在一起形成一个汇聚组，实现出、入负荷在各成员端口中的分担，同时提供更高的连接可靠性。每台路由器上最多可以创建64个Trunk接口（包括Eth-Trunk和IP-Trunk），每个Trunk接口下最多可以包含16条成员物理链路。
Trunk接口分为Eth-Trunk和IP-Trunk两种。
Eth-Trunk只能由以太网链路构成。当需要出、入负荷在多个以太网端口中进行负载分担时，可以配置Eth-Trunk接口。
IP-Trunk只能由POS链路构成。当需要出、入负荷在多个POS接口中进行负载分担时，可以配置IP-Trunk接口。
配置思路
配置Trunk接口时采用如下配置思路：
创建Trunk接口
将需要需要聚合的端口加入Trunk接口。
配置注意事项
配置Eth-Trunk接口时，对于路由器设备，二层以太网端口需要通过执行undo portswitch命令转换为三层端口，才能加入Eth-Trunk。
配置IP-Trunk的POS口链路层协议必须配置为HDLC。

组网需求
路由器RouterA与RouterB之间创建Eth-Trunk，将两个GE捆绑成一个Eth-Trunk。

配置步骤
步骤 1 配置RouterA
<Quidway> system-view
[Quidway] sysname RouterA
# 创建Eth-Trunk接口，并配置IP地址。
[RouterA] interface eth-trunk 1
[RouterA-Eth-Trunk1] ip address 100.1.1.1 24
[RouterA-Eth-Trunk1] quit
# 将端口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] eth-trunk 1
[RouterA-GigabitEthernet1/0/0] quit
[RouterA] interface gigabitethernet 2/0/0
[RouterA-GigabitEthernet2/0/0] eth-trunk 1
[RouterA-GigabitEthernet2/0/0] quit
步骤 2 配置RouterB
<Quidway> system-view
[Quidway] sysname RouterB
# 创建Eth-Trunk接口，并配置IP地址。
[RouterB] interface eth-trunk 1
[RouterB-Eth-Trunk1] ip address 100.1.1.2 24
[RouterB-Eth-Trunk1] quit
# 将端口GE1/0/0、GE2/0/0加入到Eth-Trunk 1中。
[RouterB] interface gigabitethernet 1/0/0
[RouterB-GigabitEthernet1/0/0] eth-trunk 1
[RouterB-GigabitEthernet1/0/0] quit
[RouterB] interface gigabitethernet 2/0/0
[RouterB-GigabitEthernet2/0/0] eth-trunk 1
[RouterB-GigabitEthernet2/0/0] quit
# 启用Eth-Trunk 1接口
[RouterB] interface eth-trunk 1
[RouterB-Eth-Trunk1] undo shutdown
步骤 3 验证结果
在RouterA或RouterB上执行display interface eth-trunk命令，可以看到接口状态为UP。
以RouterA的显示为例。
[RouterA] display interface Eth-Trunk 1
Eth-Trunk1 current state : UP
Line protocol current state : UP

RouterA和RouterB的Eth-Trunk接口能够互相Ping通。
