    When I did one of the nic(eth0) down, bonding stopped working but /proc/net/bonding/bond0 was showing everything fine and bond0 was showing IP too. As soon as I enabled eth0, server again started pinging. Please help

  2. Hi Navneet ,

    Please check whether second interface like eth1 is detected and its link is up using the command “ethtool eth1”.

    I’m noticing in RHEL documentation that they are recommending *NOT* to use modeprobe.conf with later RHEL releases – they recommend using “BONDING_OPTS=” in the ifcfg-bond[#] file instead so that it’s all in one place. It is supposed to work in later kernel releases.

    For round-robin if have some problem. if I down the the nic1 from the console there is no interruption in my putty session, but if I down nic2 then my putty session becoming in active until I restart the network service. Do we really need to restart the network service once the nic goes bad?

    • Hi Kiran,

      Are you testing bonding on Virtual Machines hosted on Virtual Box …?

      If you want to achieve fault tolerance and load balancing then either go for mode 5 or mode 6. As the name suggests in round robin mode packets will flow in round robin way.
