    • # nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=active-backup"
    # nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=active-backup,miimon=1000"
    ipv4配置方式
    # nmcli connection modify bond0 ipv4.addresses '192.0.2.1/24'
    # nmcli connection modify bond0 ipv4.gateway '192.0.2.254'
    # nmcli connection modify bond0 ipv4.dns '192.0.2.253'
    # nmcli connection modify bond0 ipv4.method manual
    ipv6配置方式
    # nmcli connection modify bond0 ipv6.addresses '2001:db8::1/32
    # nmcli connection modify bond0 ipv6.gateway '2001:db8::fffe'
    # nmcli connection modify bond0 ipv6.dns '2001:db8::fffd'
    # nmcli connection modify bond0 ipv6.method manual
    查看可用于绑定的接口
    # nmcli device
    DEVICE  TYPE      STATE         CONNECTION
    enp1s0  ethernet  connected     enp1s0
    enp7s0  ethernet  disconnected  --
    enp8s0  ethernet  disconnected  --
    lo      loopback  unmanaged     --
    把enp7s0和enp8s0两个接口绑定
    # nmcli connection add type ethernet slave-type bond con-name bond0-port1 ifname enp7s0
    master bond0
    # nmcli connection add type ethernet slave-type bond con-name bond0-port2 ifname enp8s0
    master bond0
    激活绑定的接口
    # nmcli connection up bond0
    查看绑定情况
    # nmcli device
    DEVICE   TYPE      STATE      CONNECTION
    ...
    enp7s0   ethernet  connected  bond0-port1
    enp8s0   ethernet  connected  bond0-port2
    启用激活从设备命令
    # nmcli connection modify bond0 connection.autoconnect-slaves 1
    重新激活绑定网卡
    # nmcli connection up bond0
    查看绑定状态信息
    # cat /proc/net/bonding/bond0
