Right :) For my tests on Cisco switch at office (without any changes on switch) and using bonding in "active-backup" mode, I can ping the active interface using bond0 IP after plugging out the network cable of the cable of active interface. Only catch was all interfaces must be on same VLAN - problem was found that one of the interface was in different VLAN and that is why ping was failing - I asked my IT guy to put all interfaces in same VLAN and everything worked like charm
Thank you all for different pointers & insights were given in the discussions. Regards,
