VCSA-DVS创建与使用LACP

 2025/06/12 

拓扑

创建新DVS

几台ESXi捆绑就选几个上行链路，一般都是两台

在DVS中创建LACP

为DVS添加与管理主机

将vmnic挂到lag中，而非port group

调整lag优先级

使其作为上行链路

交换机端配置

交换机版本:Cisco IOS switch-15.2

Tinycore数据网络通信验证

创建两台tiny-core，分别在ESXi1和ESXi2上,给他俩分别分配IP地址

sudo ifconfig eth0 192.168.1.10 netmask 255.255.255.0
sudo ifconfig eth0 up
sudo route add default gw 192.168.1.254

sudo ifconfig eth0 192.168.1.20 netmask 255.255.255.0
sudo ifconfig eth0 up
sudo route add default gw 192.168.1.254

ping 192.168.1.254

ping 192.168.1.20

可见已经可以在数据网络中通信了
