To use CRLs from ECA_CRL_PATH

1. Ensure that the CRLs for external CAs are stored in a directory and the directory path is accessible by the host.

   You can specify the CRL details that are required for external CA configuration during NetBackup installation or upgrade on the host.

   Select one of the following certificate revocation list (CRL) options during installation or upgrade:

   • Use the CRL defined in the certificate - No additional information is required.

   • Use the CRL at the following path - You are prompted to provide a path to the CRL.

     If you choose to use the Do not use a CRL option, peer host's certificate is not verified with the CRL during host communication.

   For more information, refer to the NetBackup Installation Guide.

2. Specify the CRL directory path for the ECA_CRL_PATH configuration option.
3. Ensure that the ECA_CRL_CHECK configuration option is set to a value other than DISABLE.

   During host communication, the revocation status of the external certificate is verified with the CRL in the NetBackup CRL cache that contains the CRLs from ECA_CRL_PATH.

   By default, CRLs from the cache are updated every one hour. To change the time interval, set the ECA_CRL_PATH_SYNC_HOURS option to a different value.

   To manually update the CRL cache with the ECA_CRL_PATH CRLs, run the nbcertcmd -updateCRLCache command.

   To manually delete the CRLs from the CRL cache, run the nbcertcmd -cleanupCRLCache command.
