SLES Suse Linux 11SP4 dual NIC binding bonding implementation

1. Create the Bond0 file:

#vim/etc/sysconfig/network/ifcfg-Bond0bootproto='Static'Broadcast="'ipaddr='192.168.74.141/24'NETMASK='255.255.255.0'NETWORK="'STARTMODE='Auto'Bonding_master='Yes'Bonding_slave0='eth0'bonding_slave1='eth1'bonding_module_opts='mode=1 miimon=100 fail_over_mac=1'ethtool_options="'MTU="'NAME="'remote_ipaddr="'USERCONTROL='No'

Explanation of Interpretation:
Mode 0 is expressed as load balancing mode, both NICs work (requires switch port aggregation, test failed on SLEs 12SP3 with this mode)
Mode 1 means redundancy, piece of work, piece of redundancy
Miimon indicates the system check interval time, in MS,
Fail_over_mac=1 is used when testing in VMware, otherwise the ping will be disconnected

For example: Every 100ms check once, when found a line is not through, then into another

2. Modify the NIC configuration:

#vim/etc/sysconfig/network/ifcfg-Eth0bootproto='None'#配置bond时必需将static, DHCP changed to Nonebroadcast="'ethtool_options="'ipaddr="'#配置bond时必需将IP置空MTU="'NAME='82545EM Gigabit Ethernet Controller (Copper)'NETWORK="'remote_ipaddr="'STARTMODE='off'#配置bond时必需将auto改为offUSERCONTROL='No'#vim/etc/sysconfig/network/ifcfg-Eth1bootproto='None'#配置bond时必需将static, DHCP changed to Nonebroadcast="'ethtool_options="'ipaddr="'#配置bond时必需将IP置空MTU="'NAME='82545EM Gigabit Ethernet Controller (Copper)'NETWORK="'remote_ipaddr="'STARTMODE='off'#配置bond时必需将auto改为offUSERCONTROL='No'

3. Restart the network service or restart the host operating system
