juniper QFX5100 用业务口做virtual-chassis 实例

拓扑：2台QFX5100做vc

第一台的配置：

1、set virtual-chassis member 0 mastership-priority 250 #首先将members 0 的优先级调高，默认优先级是128.

2、配置vc口，接vc线的时候尽量接成一个环状，减少故障概率。所以这里使用两条链路

request virtual-chassis vc-port set pic-slot 0 port 46 #将0/0/46口配置成vc口

request virtual-chassis vc-port set pic-slot 0 port 47 #将0/0/47口配置成vc口

第二台：

1、优先级默认就可以了

2、配置vc口

request virtual-chassis vc-port set pic-slot 0 port 46 #将0/0/46口配置成vc口

request virtual-chassis vc-port set pic-slot 0 port 47 #将0/0/47口配置成vc口

root> show virtual-chassis vc-port #查看vc口的状态
