创建vlan
vlan batch 10 20 99
进接口，trunk，放行vlan
int g0/0/1,g0/0/2
stp disable
port link-type trunk
port trunk all-pass vlan 10 20 99
创建smart组
smart-link group 1
设置master/slave端口
port g0/0/1 master
port g0/0/2 slave
配置发送控制vlan
flush send control-vlan 99 password simple 123
开抢占，默认不开，设置等待时间，默认60s

int g0/0/1
smart-link flush receive control-vlan 99 passw sim 123
int g0/0/2

sw3 dis smart-link group 1

shutdown g0/0/1

不知道是bug还是什么其他问题，0/0/2时间没有变动
