Linux - Network Bonding

Just as its name indicates, network bonding is a technique to bond a plurality of network interface together for load balance and a wider bandwidth.

The configuration of network bonding is simple. Taking ArchLinux for instance, the network bonding of 2 network interfaces (e.g., eth0 and eth1) can be configured as follows.

• /etc/systemd/network/10-bond0-eth0.network

    [Match]
    Name=eth0
  
    [Network]
    Bond=bond0

• /etc/systemd/network/10-bond0-eth1.network

    [Match]
    Name=eth1
  
    [Network]
    Bond=bond0

• /etc/systemd/network/10-bond0.netdev

    [NetDev]
    Name=bond0
    Kind=bond
  
    [Bond]
    Mode=802.3ad
    LACPTransmitRate=fast
    MIIMonitorSec=100ms

• /etc/systemd/network/10-bond0.network

    [Match]
    Name=bond0
  
    [Network]
    Address=xxx.xxx.xxx.xxx/24
    Gateway=xxx.xxx.xxx.xxx
    DNS=xxx.xxx.xxx.xxx
