网卡bond 主备模式切换失败 负载模式切换成功 为什么呢？

wushubo

做网卡的bond，配置文件如下：
root@IBM001 network-scripts]# cat ifcfg-bond0
DEVICE=bond0
BOOTPROTO=static
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.163.2
GATEWAY=192.168.163.254
TYPE=Ethernet
[root@IBM001 network-scripts]# cat ifcfg-eth0
# Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:21:5E:11:6E:4A
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
MASTER=bond0
SLAVE=yes
[root@IBM001 network-scripts]# cat ifcfg-eth2
# Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet
DEVICE=eth2
BOOTPROTO=none
HWADDR=00:10:18:8F:FD:60
ONBOOT=no
TYPE=Ethernet
MASTER=bond0
SLAVE=yes
[root@IBM001 network-scripts]# cat /etc/modprobe.conf
alias eth0 bnx2
alias eth1 bnx2
alias eth2 bnx2
alias eth3 bnx2
alias scsi_hostadapter megaraid_sas
alias scsi_hostadapter1 ata_piix
alias scsi_hostadapter2 lpfc
alias usb0 usbnet
alias peth0 bnx2
alias peth1 bnx2
alias bond0 bonding
options bond0 miimon=100 mode=1 primary=eth0

mode=1  主备模式情况下，拔下网线，没有发生切换，把mode改成0，负载模式，把网线可以成功，为什么会出现这种情况呢？

请高手指点。。。。
