Bonding load balancing not working

Solution Verified - Updated -


Using one of the load balancing bonding modes, it is perceived that the load balancing is not working properly, observations to that effect can include:

  • one interface in the bond appears to carry most of the outgoing or incoming traffic
  • the throughput during tests does not match (or approach) number_of_interfaces * interface_speed
  • Tried to bond two network cards together, but the speed is as same as the speed of one card.


  • Red Hat Enterprise Linux
  • Bonding (modes 2,4,5,6: balance-xor, lacp(802.3ad), balance-tlb, or balance-alb)
