To resolve this issue, disable transmission of Beacon Packets with vSphere Client or in the ESXi/ESX console.
To disable transmission of Beacon Packets in vSphere Client:
- Log in to vCenter Server or to the ESXi/ESX host using vSphere Client.
- Select the ESXi/ESX host on which you need to disable Beacon Probing.
- Click the Configuration tab.
- Under Software, click Advanced Settings.
- Under Net, select Net.MaxBeaconsAtOnce .
- Change the value to 0.
Note: The default is 100.
- To apply the changes, reboot the ESXi/ESX host.
To disable transmission of Beacon Packets in the ESXi/ESX console:
- Log in to ESXi/ESX host using an SSH client. For more information, see Connecting to an ESX host using an SSH client (1019852) or Tech Support Mode for Emergency Support (1003677).
- Run this command:
esxcfg-advcfg -s 0 /Net/MaxBeaconsAtOnce
- To apply the changes, reboot the ESXi/ESX host.
Note: This is a global parameter so setting this to 0 stops beacon on all vmnics (regardless of the vSwitch Settings for Network Failover Detection).
