bond0配置(bond是我在重装系统的时候做的)

网卡配置

eth0

NAME=bond0 slave 1

MASTER=a25343c6-c96c-4683-ae48-848e3fca704f

HWADDR=

TYPE=Ethernet

ONBOOT=yes

UUID=0a553f1d-85a8-4446-9ee2-88dc085a4e92

eth1

# Generated by parse-kickstart

NAME=bond0 slave 2

MASTER=a25343c6-c96c-4683-ae48-848e3fca704f

HWADDR=

TYPE=Ethernet

ONBOOT=yes

UUID=f0426c72-a3c4-4803-b797-37824fa34c87

出现的问题是：

bond0 (bond0使用的mac地址是eth1的)接口dropped 丢包每一秒丢一个包。

关掉eth0 bond0 dropped 丢包消失

以下是我截取到的http报文

tcpdump -i bond0 dst port 80
