RedHat 7 Configuration Bonding dual NIC Binding

Redhat 7 Although the new teaming technology supports dual-NIC bindings, bonding technology can still be used, but slightly different from the configuration of Redhat 6.

Configuring bond bindings for load Balancing mode

Create and edit the bond0 configuration file:vi ifcfg-bond0, and fill in the following: where mode=6 represents a different load-balancing mode for MAC addresses

Bootproto=static

Device=bond0

Name=bond0

Type=bond

Bonding_master=yes

Onboot=yes

ipaddr=192.168.10.5

Prefix=24

gateway=

dns=

Bonding_opts= "Miimon=100mode=6"

Edit the Subordinate interface profile:vi ifcfg-eno16777736, and fill in the following:

Type=ethernet

Bootproto=none

device=eno16777736

name=eno16777736

Bonding_master=yes

Onboot=yes

Master=bond0

Slave=yes

To edit the second subordinate interface configuration file: vi ifcfg-eno33554960 , and fill in the following content:

Type=ethernet

Bootproto=none

device=eno33554960

name=eno33554960

Bonding_master=yes

Onboot=yes

Master=bond0

Slave=yes

Restart the network service for BOND0 to take effect

Check the status of the network card:IP Add, the red box can be seen configured to take effect, 4 cards in the first two network cards have been effective as bond0 slave interface, and the MAC address is not the same, so the switch port does not need to do any configuration

To view the status of Bond0:cat/proc/net/bonding/bond0, you can see that the status of Bond0 is normal

Test , first long ping, then Disconnect one of the network card connection, no packet loss occurred

also see that the current active slave NIC automatically switches to eno33554960

Configuring Bond bindings for the main standby mode

Similarly, create a binding for the main standby mode for the remaining two NICs bond1,mode=1 is the primary standby mode

test: First length Ping , and then disconnect one of the network cards, no drop packets occur

both sets of bindings can simultaneously Ping Pass
