组网需求

S5720I-10X-PWH-SI-AC和S5720I-6X-PWH-SI-AC不支持此配置。

如图1所示，为了增加设备的容量采用设备堆叠技术，将Switch3和Switch4通过专用的堆叠电缆链接起来，对外呈现为一台逻辑交换机。为了实现设备间的备份、提高可靠性，采用跨堆叠设备Eth-Trunk接口技术，将不同设备上的物理接口加入同一个Eth-Trunk接口。在网络无任何故障情况下，在PE设备上查看成员口信息时，发现VLAN2的数据流量会通过成员口GE1/0/1和GE1/0/2转发，VLAN3的数据流量通过成员口GE1/0/1和GE1/0/2转发。增加了堆叠设备之间的带宽承载能力，也降低了流量转发效率。

为了有效保证VLAN2的数据流量通过成员口GE1/0/1转发，VLAN3的数据流量通过成员口GE1/0/2转发，可在堆叠设备上使能Eth-Trunk接口流量本地优先转发功能。

配置思路

采用如下的思路配置Eth-Trunk接口流量本地优先转发功能：

创建Eth-Trunk接口。
加入Eth-Trunk的成员接口。
使能Eth-Trunk接口流量本地优先转发功能。
配置各接口加入相应VLAN，实现二层互通。

操作步骤

1.创建Eth-Trunk接口，并配置允许通过的VLAN

# 配置Stack。

<HUAWEI> system-view
[HUAWEI] sysname Stack
[Stack] interface eth-trunk 10
[Stack-Eth-Trunk10] port link-type trunk 
[Stack-Eth-Trunk10] port trunk allow-pass vlan all
[Stack-Eth-Trunk10] undo port trunk allow-pass vlan 1
[Stack-Eth-Trunk10] quit

2.配置PE

<HUAWEI> system-view
[HUAWEI] sysname PE
[PE] interface eth-trunk 10
[PE-Eth-Trunk10] port link-type trunk
[PE-Eth-Trunk10] port trunk allow-pass vlan all
[PE-Eth-Trunk10] undo port trunk allow-pass vlan 1
[PE-Eth-Trunk10] quit

2.加入Eth-Trunk的成员接口

# 配置Stack。
