[Linux-cluster] Ethernet Channel Bonding Configuration Clarification is Needed

[Alan A]

You have to look for the bonding option in /etc/modprobe.conf .. Mode 1 is
going to use only one NIC at the time and engage the other NIC only if the
first one fails. Try mode 0 which is round robin or mode 5 or 6.
