Run the display pki certificate filenamefile-name to check whether the certificate exists.
If not, use methods such as SFTP to upload the certificate to the storage medium of the device.
If so, go to step 2.
Check whether the imported certificate file name meets requirements.
If not, change the certificate file name in accordance with requirements.
If so, go to step 3.
Run the pki import-certificate peer command to check whether the certificate format selected during certificate import is correct.
If not, select the correct certificate format when importing the certificate.
If so, go to step 4.
Run the dir and display pki credential-storage-path commands in the user view to check whether the certificate storage path is the same as the default storage path of the certificate.
If not, save the certificate to the default storage path.
If so, go to step 5.
Run the display pki peer-certificate command to check whether the same certificate has been installed on the device or whether the same issuer and subject certificates exist on the device.
If so, run the pki release-certificate peer command in the system view to delete this certificate.
If not, go to step 6.
