ARP monitoring on an active-backup Bond associated to a Bridge does not work

Updated 2013-05-16T02:40:03+00:00

Issue

When a Bridge interface is associated with a Bonding interface using ARP monitoring, the network path is not functional as eth0/eth1 of the host are always detected down.
When the Bond interface is configured with MII mode, the network path towards the virtual machines is functional.
Note that if the Bonding is used without the associated bridge interface, the ARP monitoring mode is functional.

Environment

  • Red Hat Enterprise Linux 5 (RHEL5)

  • Bonding mode active-backup (mode 1)

  • Bridge attached to Bond device

  • ARP monitoring (arp_ip_target)
