Ethernet Bonding

taxbagetz

I am trying to bond two interfaces (eth1 and eth2) with mode bonding mode 1 (active-backup). I have successfully set it up but when I try to test it by pulling the cable on eth1, it switched to eth2 but bond0 IP is no loger reacheable.

# bond0 #

DEVICE=bond0

USERCTL=no

BOOTPROTO=dhcp

ONBOOT=yes

# eth1 #

DEVICE=eth1

USERCTL=no

ONBOOT=yes

MASTER=bond0

SLAVE=yes

BOOTPROTO=none

# eth2 #

DEVICE=eth2

USERCTL=no

ONBOOT=yes

MASTER=bond0

SLAVE=yes

BOOTPROTO=none

# modprobe.conf #

alias bond0 bonding

options bond0 mode=1 miimon=100 primary=eth1

Done issuing modprobe -r bonding and below is the /proc result for bond0 after I pulled the cable on eth1. It switched to eth2 but bond0 IP is no longer reacheable.

# /proc/net/bonding/bond0 #
