【原创】H3C交换机链路聚合配置

图示
在这里插入图片描述

中间两个交换机,使用两根网线直连,这样本来是10G级联,变成了20G级联。

在默认情况下,这两根线在STP协议下,只有一路是通的,另一路处于备用状态。如果要将这两路都设置为级联,那么还需要一些其它设置。

首先在每个交换机上分别创建一个聚合接口

interface Bridge-Aggregation 1
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic

接下来,将交换机上的这两个接口添加到聚合组就好了

#
interface Ten-GigabitEthernet1/0/50
 port link-type trunk
 port trunk permit vlan all
 port link-aggregation group 1
#
interface Ten-GigabitEthernet1/0/51
 port link-type trunk
 port trunk permit vlan all
 port link-aggregation group 1

查看接口时,会发现有一个叫做BAGG1的接口,20G。

FGE1/0/54            DOWN 40G     A      A    1

OK,配置完成。
