When ESXi hosts are connected to a vSphere Distributed Switch and the Network Health Check is enabled, you experience these symptoms:
  • The Events view in the vCenter Server Tasks & Events tab reports constant alarms similar to:

    Alarm 'vSphere Distributed Switch teaming matched status' on x.x.x.x changed from Green to Red
  • In the /var/log/hostd.log file of the ESXi host, you see this entries similar to:

    Teaming configuration in the vSphere Distributed Switch on host hostname does not match the physical switch configuration in ha-datacenter. Detail: No loadbalance_ip teaming policy matches.


VMware vSphere ESXi 5.1
VMware vSphere ESXi 5.5
VMware vSphere ESXi 6.0
VMware vSphere ESXi 6.5
VMware vSphere ESXi 6.7
VMware vSphere ESXi 7.0
VMware vSphere ESXi 8.0


This issue occurs when the Network Health Check feature detects a teaming parameter misconfiguration due to one of these scenarios:
  • The IP Hash teaming policy is configured for the vSphere Distributed Switch but the uplink ports are not configured in a port-channel setting.
  • The uplink ports are configured in a port-channel setting but the IP Hash teaming policy is not set for the vSphere Distributed Switch.
  • SR-IOV is configured on an ESXi host

Additional Information

Depending on the options that you select, vSphere Distributed Switch Health Check can generate a significant number of MAC addresses for testing teaming policy, MTU size, VLAN configuration, resulting in extra network traffic. For more information, see Network health check feature limitations in vSphere (2034795).

After you disable the vSphere Distributed Switch Health Check, the generated MAC addresses age out of your physical network environment according to your network policy. For more information, see the Enable or Disable vSphere Distributed Switch Health Check section of the vSphere Networking Guide,
