Severity: 3-Major


When using "tmsh install sys crypto cert cert_name from-local-file /cert_path/cert_file.crt" command, if a cert with the same name has already exists, it should still allow the cert import and overwrite the existing cert if "no-overwrite" is not specified in this tmsh command. However, it fails to overwrite the cert in this case, and still complains that "The requested cert(cert_name.crt) already exists in this scope."


Unable to simultaneously update and overwrite a certificate using tmsh.


-- Using "tmsh install sys crypto cert" to import a cert -- The "no-overwrite" option is not specified in the tmsh command. -- The specified cert name already exists.


Although you cannot simultaneously update and overwrite the cert using tmsh, you can achieve the same result using these separate steps: 1. To remove the cert, which prevents the existing cert-overwrite situation, run the following command: tmsh install sys crypto cert cert_name. 2. Run the following command to update the cert: tmsh cert import command.

Fix Information

The existing cert can be overwritten using the tmsh cert import command "tmsh install sys crypto cert cert_name from-local-file /cert_path/cert_file.crt".
