Bonding NICs
This worked in RHEL4 for swamp.

The example assumes you have two network interfaces, eth0 and eth1.

First make sure these entries appear in /etc/modprobe.conf
alias bond0 bonding
options bonding mode=1 miimon=100 primary=eth0


Now setup the ifcfg files...

/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
IPADDR=192.168.1.1 #adjust
NETMASK=255.255.255.0 #adjust
ONBOOT=yes
TYPE=Ethernet


/etc/sysconfig/network-scripts/ifcfg-ethX (where ethX=eth0 or ethX=eth1)
DEVICE=ethX #adjust
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
ONBOOT=yes

View running bonded nic:
cat /proc/net/bonding/bond0
