Run the display pki crl filenamefile-name to check whether the CRL file exists.
If not, use methods such as SFTP to upload the CRL file to the storage medium of the device.
If so, go to step 2.
Check whether the CRL file name meets requirements.
If not, change the CRL file name in accordance with requirements.
If so, go to step 3.
Check whether the CRL file format is correct.
If not, use the CRL file format supported by the device, for example, DER and PEM.
If so, go to step 4.
Run the dir and display pki credential-storage-path commands in the user view to check whether the CRL file storage path is the same as the default storage path of the CRL file.
If not, save the CRL file to the default storage path.
If so, go to step 5.
Collect required information and contact technical support personnel.
