NSX-T – Topology view troubleshooting

Ever seen the beneath picture when trying to see the cool topology view in NSX-T?

If so, there is an API call that can help you resync the topology view so you again can see it.

# Login details
$nsxUsername = "admin",
$nsxPassword = "",
$nsxmanager = "nsxt.home.lab"

# NSX Manager auth header
$Type = "application/json;charset=UTF-8"
$Header = @{"Authorization" = "Basic " + [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($nsxUsername + ":" + $nsxPassword)) }
$nsxUri = "https://$($nsxmanager)"

# Request topology resync
Invoke-RestMethod -Uri "$nsxUri/policy/api/v1/ui/network-topology/resync" -Headers $Header -Method POST -ContentType $Type

You don’t get any feedback from the API call, but after a few minutes, you will again be able to see the topology again.
