You simply configure the slaves in /etc/sysconfig/network-scripts:
/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
SLAVE=yes
MASTER=bond0
/etc/sysconfig/network-scripts/ifcfg-eth1:
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
SLAVE=yes
MASTER=bond0
And set up your bond device:
/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=static
BONDING_MASTER=yes
BONDING_SLAVE0=eth0
BONDING_SLAVE1=eth1
IPADDR=www.xxx.yyy.zzz
NETMASK=aaa.bbb.ccc.ddd
Edit /etc/modprobe.conf and add these lines if they're not already
there:
alias bond0 bonding
options bond0 mode=mode-string miimon=100
"mode-string" is one of the available mode strings:
balance-rr ("0"): Balanced round-robin (default)
active-backup ("1"): Active-passive failover
balance-xor ("2"): Use transmit hash algorithm
broadcast ("3"): Broadcast (transmit on all slaves)
802.3ad ("4"): Use dynamic link aggregation
balance-tlb ("5"): Transmit load balance based on NIC load
balance-alb ("6"): Adaptive load balance
(you can use the number in the parenthesis instead of the string, e.g.
"mode=2").
Then "service network restart" and it should be alive and kicking in
whatever mode you specified.
This is all described in the
/usr/share/doc/kernel-doc*/Documentation/networking/bonding.txt
file if you installed the kernel-doc RPM.
