Setting up bonding aka nic teaming on Linux Systems

setup

look for options on how to setup the module

modinfo bonding | grep mode
modinfo bonding | grep xmit

see bonding-rr for raw load-balance

see bonding-lacp (preferred) for high-availability done right

additional notes

load-balance algorightm

note default xmit is 0 aka layer2

slackware-specific

    ls -lF /etc/rc.d/rc.modules
    ls -lF /etc/rc.d/rc.modules.local # nothing about bonding
    ls -lF /etc/modprobe.conf         # noexist and DEPRECATED unless forced with -C
    ls -lF /etc/modprobe.d/           # nothing about bonding
    vi /etc/rc.d/rc.inet1

proceed with network setup as usual or as a bridge but against the bond0 interface instead

rhel7-specific

systemctl stop NetworkManager
systemctl disable NetworkManager

cd /etc/sysconfig/network-scripts/
vi ifcfg-bond0

NAME=bond0
DEVICE=bond0
IPADDR=IP_ADDRESS
PREFIX=24
ONBOOT=yes

vi ifcfg-eth0

NAME=eth0
DEVICE=eth0
MASTER=bond0
SLAVE=yes
ONBOOT=yes

same for eth…

tail -F /var/log/messages
systemctl restart network

systems from the past

obsolete way to do things

ifenslave -a
ifenslave bond0 eth0
ifenslave bond0 eth2
ifenslave bond0 eth3
