    Port-Channel and Linux Bonding

    dime New Member

      Ok, so it took me a while to get my head around 'active' only (static) and which Linux mode that correlated with... So, I figured I would post my configs here to save others some time.  The take away is that you can't test the bond with ping as with Redhat 6 the kernel drops the packets thinking they are spoofs.  (Thanks Evan for all you help! )

       

      SERVER CONFIGs

      cat ifcfg-bond0

      #HWADDR=00:01:02:03:04:00
