Using Commands

Using Commands

This section uses CentOS 7.4 as an example to describe how to configure bonding using commands.

This method takes effect temporarily. After the network service is reset in the OS or the OS is restarted, the configuration is lost.

  1. Log in to the server OS as the root user, right-click the OS desktop, and choose Open Terminal from the shortcut menu.
  2. Run the following command to find the port in the up state:


  3. Run the following commands in sequence to create bond0 (ports enp6s0 and enp7s0 are examples):

    modprobe -first-time bonding

    echo X > /sys/class/net/bond0/bonding/mode #The X value can be 1, 2, or 4.

    • In the preceding command, X specifies the bonding mode.
    • If mode is set to 1, the switch is configured properly. If mode is set to 2, the switch must be configured with a trunk. If mode is set to 4, the trunk of the switch must be configured to the static LACP mode. It is recommended that the rate be set to the same value as that of bonding.
    • If mode is set to 4, you need to configure lacp_rate.

      echo 1 > /sys/class/net/bond0/bonding/lacp_rate

    ifconfig bond0 up

    ifenslave bond0 enp6s0 enp7s0

    echo 100 > /sys/class/net/bond0/bonding/miimon #miimon: interval for checking the network, in milliseconds

  1. Run the following command to create an IP address of bond0:

    ifconfig bond0 IP #IP specifies the IP address of bond0.
