some questions on device Trust Certificate?

Hi Herman2024,

If the certificate is the same, you can delete it, but before saving a UCS, duplication could happen in the bigip_add process if it were executed a couple of times, or maybe someone in your company uploaded the certificate after the bigip_add, but it is a little weird. I recommend you generate new self-signed certificates with the name of the hosts for the LTM and GTM devices to avoid generic certificates with the same name.
