3-8 Aruba交换机实用配置-链路聚合 2020

实例拓扑如下：

两台核心双线连接，达到捆绑增加带宽负载均衡效果

链路聚合配置

最好的做法是在两侧都配置了链接聚合之后再连接接口；

1，创建链路聚合接口
Core-1(config)# trunk a19-a20 trk1 trunk
2. You must define the VLAN settings on the trunk interface.
Core-1(config)# vlan 11 tag trk1
Core-1(config)# vlan 12 tag trk1

Core-2
Core-2(config)# trunk a19-a20 trk1
Core-2(config)# vlan 11 tag trk1
Core-2(config)# vlan 12 tag trk1

2，链路聚合状态
Core-2(config)# show trunk
Load Balancing Method: L3-based (default)
Port | Name Type | Group Type
------ + -------------------------------- ---------- + ------ --------
A19 | Core-1 100/1000T | Trk1 Trunk
A20 | 100/1000T | Trk1 Trunk

Core-2(config)# show vlan 11
Status and Counters - VLAN Information - VLAN 11
VLAN ID : 11
Name : VLAN11
<-output omitted->
Port Information Mode Unknown VLAN Status
