Interface bonding / Link aggregation (Multiple)
Hello,
I've been using mode 4 with four slaves, however looking at ifconfig showed that the traffic was not balanced correctly between the interfaces, the outgoing traffic has been alot higher on the last slave.
Example:
eth0 RX 123.2 GiB TX 22.5 GiB
eth1 RX 84.8 GiB TX 8.3 GiB
eth2 RX 198.7 GiB TX 11.1 GiB
eth3 RX 78.2 GiB TX 1.7 TiB
A) What could possibly be the source of such an issue?
B) Is it possible to make two bond interfaces in mode 4 and then have them round-robin?
Something like this:
bond0 (mode 4)
*eth0
*eht1
bond1 (mode 4)
*eth2
*eth3
and then have both round-robin, so:
bond2 (mode 0)
*bond0
*bond1
Any help is highly appreciated and thanks in advance guys

IFCFG-BONDING(5) Network configuration IFCFG-BONDING(5) NAME
ifcfg-bonding - interface bonding configuration SYNOPSIS
/etc/sysconfig/network/ifcfg-bond* Bonding Interfaces To setup a bonding interface you need a configuration file ifcfg-bond<X> with the usual network settings. But you must add additional vari- ables BONDING_MASTER must be set to 'yes' to identify this interface as a bonding interface BONDING_SLAVE_<X> here you specify the interface name representing the slave network interfaces. BONDING_MODULE_OPTS contains bonding options. Here you can set interface timeouts or working modes ('mode=active-backup' for backup mode). For addi- tional information take a look into the documentation mentioned at the bottom. Note, that this options are not passed as parameters to the bonding kernel module any more, but set via sysfs interface. This variable will be renamed in the feature. BONDING_SKIP_REMOVE_WORKAROUND When set to "yes", a bonding interface will be not removed while ifdown any more to avoid problems, e.g. when some third party ker- nel module, such as Veritas 'llt' module, does not react correctly to the UNREGISTER event and does not remove its references to the bonding interface causing all network related operation to stuck. Note: the bonding options are not reverted when this option is enabled and it is required to either explicitly keep the old options and set them to their default setting on bonding configuration changes or to reboot. Example Example for a bonding interface on eth0 and eth1 using the backup mode ifcfg-bond0 STARTMODE='onboot' BOOTPROTO='static' IPADDR='192.168.0.1/24' BONDING_MASTER='yes' BONDING_SLAVE_0='eth0' BONDING_SLAVE_1='eth1' BONDING_MODULE_OPTS='mode=active-backup miimon=100' Additional Information For additional and more general information take a look into /usr/src/linux/Documentation/networking/bonding.txt. Maybe you need to install the kernel sources to get this additional documentation. The configuration of routes for this kind of interface does not differ from ordinary interfaces. See man routes for details. BUGS
