sudo cat /etc/network/interfaces
auto em1.12
iface em1.12 inet static
address 120.52.139.9
netmask 255.255.255.240
gateway 120.52.139.1
auto em1.13
iface em1.13 inet static
address 123.58.236.26
netmask 255.255.255.248
auto em1.16
iface em1.16 inet static
address 223.71.150.91
netmask 255.255.255.248
4、激活vlan子接口
