Workaround:
To work around this issue, confirm that the switch is disabled by running the command 'net-dvs -l' and look for the com.vmware.vswitch.disabled property. If it exist and is set to true, then the switch is affected.

-- esxcfg-vswitch -l
This will list all the switches on the host.  This command will provide the name of the switch

-- net-dvs -s "com.vmware.vswitch.disabled=false" -p hostPropList <<switch name>>

-- Recommended option: Call NSX API to update the transport node configuration to the host
