交换机做trunk模式

配置好bond0

HCS: # cd /etc/sysconfig/network/scripts/

检查内核要支持VLAN功能：

HCS:/etc/sysconfig/network/scripts # dmesg | grep -i VLAN

确认802.1q模块加载：

HCS:/etc/sysconfig/network/scripts # lsmod | grep 8021q

使用vconfig命令增加子接口：

HCS:/etc/sysconfig/network/scripts # vconfig add bond0 100

Added VLAN with VID == 100 to IF -:bond0:-

HCS:/etc/sysconfig/network/scripts # vconfig add bond0 200

Added VLAN with VID == 200 to IF -:bond0:-

配置接口IP：（配置在network/目录下）

HCS:/etc/sysconfig/network # cat ifcfg-vlan100

DEVICE='vlan100'

ETHERDEVICE='bond0'

STARTMODE='auto'

IPADDR='172.16.1.21'

NETMASK='255.255.255.0'

HCS:/etc/sysconfig/network # cat ifcfg-bond0.200

DEVICE='vlan200'

ETHERDEVICE='bond0'

STARTMODE='auto'

IPADDR='172.16.1.21'

NETMASK='255.255.255.0'

检查生效
