Linux NIC bond configuration under VMware Virtual machine environment

VMware Workstation 12

Normal real-world environment, the network card to do Bond Configure the following (False Set is a bond0 ) :

1, Ifcfg-eth0

Device=eth0

Onboot=yes

Master=bond0

Bootproto=none

Slave=yes

2, Ifcfg-eth1

Device=eth1

Bootproto=none

Master=bond0

Slave=yes

Onboot=yes

3 ,ifcfg-bond0

Device=bond0

Bootproto=static

ipaddr=172.16.3.22

netmask=255.255.248.0

Onboot=yes

broadcast=10.1.7.255

4,/etc/modprobe.conf

After the original file content, append the following configuration:

Alias Bond0 Bonding

Options Bond0 miimon=100 mode=1

Configuration Explanation : miimon=100 , the system every 100ms Monitor the link connection status once, mode=1 , which means the NIC eth0,eth1 using hot Standby mode ( if mode=1, it means that eth0 and eth1 are in load-balanced mode )

5,/etc/rc.local

After the original file content, append the following configuration:

Ifenslave bond0 eth0 eth1

Configuration Explanation : Specify the hot standby mode eth0 and the eth1 working order of network cards

6 , Restart the server

different from the real-world environment, VMware the virtual machine gives Linux system to do bond0 NIC configuration, as done, the test found Down off eth0 after the bond0 Network card Ping does not work, unable to play the network card backup effect.

looked up the information and found it necessary to bond0 Add a parameter configuration to the configuration file, i.e. the modified bond0 The network card configuration file is as follows:

Device=bond0

Bootproto=static

ipaddr=172.16.3.22

netmask=255.255.248.0

Onboot=yes

broadcast=10.1.7.255

Bonding_opts= "Fail_over_mac=1"

Configuration Explanation : default fail_over_mac=0 , when an error occurs, change only slave of the mac Do not change Bond ; fail_over_mac=1 , you only change Bond Do not change slave .

after the change, Service Network Restart Restart The network adapter configuration, Down off eth0 , bond0 it'll make sense.
