Introducing the configuration and debugging of centos7 bond

The following tutorial column will introduce the configuration and debugging of centos7 bond to you in the centos tutorial column. I hope it will be helpful to friends in need!

First, when doing bond, there are usually more than two network cards. In /etc/sysconfig/network -scripts/, change the content of the network card you need to bond to as follows:

TYPE=Ethernet 
BOOTPROTO=none 
DEVICE=p6p2 
ONBOOT=yes 
MASTER=bond0 
SLAVE=yes

Second, create ifcfg-bond0 in the above directory (this is just a new name, you can also create other names), Add in this file:

DEVICE=bond0 
TYPE=Bond 
NAME=bond0 
BONDING_MASTER=yes 
BOOTPROTO=static 
USERCTL=no 
ONBOOT=yes 
IPADDR=xxx.xxx.xxx.xxx（ip地址） 
NETMASK=xxx.xxx.xxx.xxx(子网掩码) 
GATEWAY=xxx.xxx.xxx.xxx(网关) 
BONDING_OPTS=”mode=4 miimon=100”

3. Restart the network
4. Remarks
Here is a brief introduction to the bond mode. Detailed instructions can be found on Baidu

mode=0 ，（平衡抡循环策略） 
mode=1，（主-备份策略） 
mode=2，（平衡策略） 
mode=4，（ IEEE 802.3ad 动态链路聚合，需要交换机配置） 
mode=5, 
mode=6

miimon: Specify the MII link monitoring frequency in milliseconds (ms). This will determine how often the driver checks the link status of each slave. 0 means disabling MII link monitoring. 100 can be used as a good starting reference value.
