ifenslaveの導入

# apt-get install ifenslave
# modprobe bonding
# lsmod | grep bonding

# vi /etc/modules

bonding

# vi /etc/modprobe.d/bonding.conf

alias bond0 bonding
  options bond0 mode=1
(/etc/modprobe.d/bonding.conf で options bond0 mode=1はなくてもよさそう）

# vi /etc/network/interfaces

iface eth0 inet manual
#iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
#iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
    bond-give-a-chance 10

auto bond0
iface bond0 inet dhcp
  bond-mode 1
  bond-miimon 100
  slaves eth0 wlan0
  bond-primary eth0
 (active-backupを設定)

# vi /etc/dhcpcd.conf

denyinterfaces eth0 wlan0

# /etc/init.d/networking stop
