This document (7004571) is provided subject to the disclaimer at the end of this document.
SUSE Linux Enterprise Server 10 Service Pack 1
BONDING_MODULE_OPTS='mode=active-backup miimon=10 use_carrier=0'
messages like the following can be found in /var/log/messages
bonding: bond2: Warning: the permanent HWaddr of eth3 - 00:1f:29:c7:54:9c - is still in use by bond2. Set the HWaddr of eth3 to a different address to avoid conflicts.
BONDING_MODULE_OPTS='mode=1 miimon=100 fail_over_mac=follow use_carrier=1'
one thing is not to use the deprecated ethtools (carrier=1) and the second is explained in /usr/src/linux/Documentation/networking/bonding.txt under "follow or 2" which recommends this setting for multiport nics.
