I was recently trying to replace some service certificates and I accidentally associated the certificate with the wrong service. When trying to delete the certificate I was presented with an error “Certificate delete failed: Certificate cannot be deleted because it is used by 1 MP node” The first step I did was try to figure out what service is associated with the certificate. For that I leveraged the instructions in KB 75277. Performing a GET /api/v1/trust-management/certificates/{cert-id} I was able to identify that CBM_API service was using the certificate. ...

Important correction (August 25, 2026): The original article incorrectly implied that the NSX Edge Removal Tool preserves attached dependencies and that dependencies could be addressed after removal. Broadcom’s current instructions require administrators to remove or disconnect added services, interfaces, segments, and other dependencies before running the cleaner. The tool must not be used for an Edge cluster serving Workload Control Plane (WCP). The old direct-download link, version-specific filename, executable command, and post-removal dependency workflow have been removed so they cannot be mistaken for current instructions. ...

I recently ran in to a problem where I couldn’t delete an NSX segment so I went exploring the API. The API guide can be found here The method used is delete policy/api/v1/infra/segments/{segment-id}?force=true It would look like this in Postman: To list the segments we can use a get request towards /policy/api/v1/infra/segments/ ...

Important safety update (August 25, 2026): Do not manually remove NSX VIBs with esxcli software vib remove. Broadcom documents that this method is unsupported and can cause loss of management or workload networking. The executable removal guidance previously shown on this page has been removed. Use the current follow-up instead: Safely Removing Stale NSX VIBs from an ESXi Host. It starts with the NSX Manager removal workflow and covers the narrower stale-package condition where Broadcom directs administrators to use nsxcli -c del nsx while the host is in maintenance mode. ...

I needed to create a few additional accounts in NSX-T for outside sources. Instead of creating individual accounts I wanted to use the existing ones from AD. To get started we need to get the certificate from the vIDM server. Log on to the vIDM server as root and run the following: openssl1 s_client -connect <FQDN of vIDM host>:443 < /dev/null 2> /dev/null | openssl x509 -sha256 -fingerprint -noout -in /dev/stdin Next, create the OAuth client ID in vIDM. Log in to the vIDM UI as an administrator at https://<FQDN-of-vIDM-host>/SAAS/admin/app/page#!/dashboard, then navigate to Catalog -> Settings. ...
