Issue/Introduction

Symptoms:

When ESX/ESXi 4.x and 5.x hosts use Beacon Probing, you experience these symptoms:

• The Network redundancy lost alarm is triggered across a chassis when any of the blades reboot
• ESX/ESXi 4.x and 5.x hosts indicate that a vmnic goes down briefly in Events

Environment

VMware vSphere ESXi 5.5
VMware vSphere ESXi 5.0

VMware ESXi 4.0.x Installable
VMware ESX 4.0.x

Resolution

This issue occurs if the number of active NICs is less than three. For Beacon Probing to be effective, you must have at least three active NICs.

To resolve this issue, verify the network failover detection settings and ensure that Beacon Probing is used only when there are at least three active NICs configured for the vSwitch.
