雙網(wǎng)卡bond1的配置問題

yurenyahe

雙網(wǎng)卡BOND1測試，當(dāng)前活動網(wǎng)卡在ETH2時可以正常，切到ETH3時網(wǎng)絡(luò)不通是什么問題？

環(huán)境描述：

1、VMWARE虛擬機，雙網(wǎng)卡，ifcfg-eth2、ifcfg-eth3、ifcfg-bond0，VMWARE網(wǎng)絡(luò)為“僅主機”

2、配置如下：

網(wǎng)卡ifcfg-eth2配置：

DEVICE=eth2
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
MASTER=bond0
SLAVE=yes

網(wǎng)卡ifcfg-eth3配置：

DEVICE=eth3
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
MASTER=bond0
SLAVE=yes

ifcfg-bond0

DEVICE=bond0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.222.105
BROADCAST=192.168.222.255
NETMASK=255.255.255.0
GATEWAY=192.168.222.101
DNS1=192.168.222.104
USERCTL=no
TYPE=Ethernet
BONDING_OPTS="mode=1 miimon=200"

以下是bond0的狀態(tài)情況，是可以實現(xiàn)自動切換，但切到eth3網(wǎng)絡(luò)就不通了。
