RHEL7: Remote IP inaccessible via LACP bond when network service restarted

Solution In Progress - Updated -

Issue

  • Expect to see ARP entry marked with neighbor MAC address. Instead it is being marked as 'incomplete'. Even though when running a tcpdump it is showing that the ARP reply for the bonding MAC is actually being received.

Environment

  • Red Hat Enterprise Linux
    • RHEL7 kernels
  • LACP bond with 2 slaves
  • Cisco enic
