Hi,
I have understood that chrome no longer support the common name field and instead requires the Subject Alternative Name field to be populated.
When you install a valid certificate on your switches (mostly 2530 and 2930F) have you checked whether Internet explorer is okay with the certificates and how they respond ?
The CA should be automatically adding the CN as a SAN(Subject Alternative Name). If they’re not, you should reach out to their support.
Thank You
