Boost Reliability with Ethernet Bonding and Linux - Page 2
Best of ENP: The Linux kernel comes with what you need to do Ethernet bonding. It takes a few steps to implement, but the payoff comes in the form of boosted bandwidth and improved reliability.
Starting Everything At Boot
To load the module with the options you want at boot, edit /etc/modprobe.d/arch/i386and add these lines. Ignore any documentation that tells you to use a different file because that is wrong:
alias bond0 bonding
options bond0 mode=balance-alb miimon=100
Then enshrine your settings in /etc/network/interfaces, using your own addresses of course:
auto bond0
iface bond0 inet static
address
netmask 255.255.255.0
network
192.168.1.0
broadcast
192.168.1.255
gateway
192.168.1.50
up /sbin/ifenslave bond0 eth0 eth1
down ifenslave -d bond0 eth0 eth1
bond0 Status
Take a look at the contents of /proc/net/bonding/bond0to see how your new interface is faring:
$ /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.1.1 (September 26, 2006)
Bonding Mode: adaptive load balancing
Primary Slave: eth0
Currently Active Slave: eth1
MII Status: up

Now what? In the second partyou'll learn some additional configuration options for different roles such as round-robin or failure-only, how to configure bonding on Fedora, some tips on network topology, and how to troubleshoot problems.
