If it is confirmed the NSX Segment is stale in the vCenter Network Inventory, please proceed with the following steps:

Note: It is advised to take a backup of the vCenter before proceeding with the following steps:

1. Identify the dvs-ID by selecting the DVS in which the Segment is a part of and view the ID from the Browser URL.
2. Identify the dvportgroup-id by selecting the Stale NSX Segment from the vCenter Network Inventory and grabbing the ID from the Browser URL
3. Login to vCenter Server MOB by going to the following URL:
   
   https://vCenter_FQDN/mob/?moid=dvs-##&method=removeNsxPortgroups
   dvs-## was found in step 1. (There is no need to include UUID after ":")
4.  Copy and paste the following snippet into the parameters field to remove the specific dvportgroup-id:

<portgroupKey>dvportgroup-##</portgroupKey>
dvportgroup-id was found in step 2. (There is no need to include UUID after ":")

Note: There is no impact to the vCenter when running these MOB commands. No vCenter or NSX restarts are required as a result.
