SW1配置
System View: return to User View with Ctrl+Z.
[SW1]interface Bridge-Aggregation 1 (创建聚合端口)
[SW1-Bridge-Aggregation1]quit
[SW1]int e0/4/0
[SW1-Ethernet0/4/0]port link-aggregation group 1 把物理端口加入聚合组
[SW1-Ethernet0/4/0]int e0/4/1
[SW1-Ethernet0/4/1]port link-aggregation group 1
[SW1-Ethernet0/4/1]int e0/4/2
[SW1-Ethernet0/4/2]port link-aggregation group 1
[SW1-Ethernet0/4/2]
SW2配置
System View: return to User View with Ctrl+Z.
[SW2]interface Bridge-Aggregation 1
[SW2-Bridge-Aggregation1]int e0/4/0
[SW2-Ethernet0/4/0]port link-aggregation group 1
[SW2-Ethernet0/4/0]int e0/4/1
[SW2-Ethernet0/4/1]port link-aggregation group 1
[SW2-Ethernet0/4/1]int e0/4/2
[SW2-Ethernet0/4/2]port link-aggregation group 1
[SW2-Ethernet0/4/2]
结果
用命令display link-aggregation summary查看链路聚合的状态
结论
① 链路聚合是以太网交换机实现的高可靠性技术链路聚合将多个物理以太网聚合在一起形
成一个逻辑上的聚合端口组
② 不需要考虑环路
优点
① 增加链路带宽
提高链路可靠性
