ESXi host is reporting "Mismatch" error on the NSX UI -- Host that has a configuration that does not match other host in this cluster

Products

• VMware NSX

Issue/Introduction

 - One of more ESXi hosts would report an error " Host that has a configuration that does not  match other host in this cluster" on the NSX UI.

 

Environment

VMware NSX

 

Cause

• While a TNP represents the global configuration applied to a Host Switch, a sub-TNP represents the local configuration applied to a sub-cluster.
• When you apply a sub-TNP to a sub-cluster, the host switch is overridden on the sub-cluster.
• You can only apply a sub-TNP to a VDS switch

Resolution

•  We referred this tech document which states that sub-TNP can only override the following fields of a global TNP: VDS Host Switches ID, uplink profiles and IP assignment -  https://techdocs.broadcom.com/us/en/vmware-cis/nsx/vmware-nsx/4-1/installation-guide/host-transport-nodes/preparing-esxi-hosts-as-transport-nodes/sub-tnps-and-sub-clusters.html 
•  If any of the fields are overridden in the sub-TNP or TNP there will be a mismatch error reported in the NSX UI. In case the mismatch has to be addressed DO NOT MAKE ANY CHANGES WITHOUT CUSTOMER CONSENT AS THIS MAY LEAD TO OUTAGE
