z If a PKI domain already has a CA certificate, you cannot retrieve another CA certificate for it. This is
in order to avoid inconsistency between the certificate and registration information due to related
configuration changes. To retrieve a new CA certificate, use the pki delete-certificate command
to delete the existing CA certificate and local certificate first.
z The pki retrieval-certificate configuration will not be saved in the configuration file.
z Be sure that the device system time falls in the validity period of the certificate so that the certificate
is valid.
Configuring PKI Certificate Verification
A certificate needs to be verified before being used. Verifying a certificate is to check that the certificate
is signed by the CA and that the certificate has neither expired nor been revoked.
Before verifying a certificate, you need to retrieve the CA certificate.
You can specify whether CRL checking is required in certificate verification. If you enable CRL checking,
CRLs will be used in verification of a certificate.
