• Prepare for certificate verification.
Before retrieving a local certificate in online mode, be sure to complete LDAP server configuration.
If a PKI domain already has a CA certificate, you cannot retrieve another CA certificate for it. This
restriction helps avoid inconsistency between the certificate and registration information resulted from
configuration changes. To retrieve a new CA certificate, use the pki delete-certificate command to delete
the existing CA certificate and the local certificate first.
Make sure the device system time falls in the validity period of the certificate so that the certificate is valid.
To retrieve a certificate manually:

manually
• In online mode:
pki retrieval-certificate { ca | local } domain
domain-name
• In offline mode:
pki import-certificate { ca | local } domain
domain-name { der | p12 | pem } [ filename
filename ]
Use either command.
The pki retrieval-certificate
configuration is not saved in
the configuration file.
Verifying PKI certificates
A certificate needs to be verified before being used. Verifying a certificate will check that the certificate
is signed by the CA and that the certificate has neither expired nor been revoked.
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. In this case, be sure to retrieve the CA certificate and
CRLs to the local device before the certificate verification. If you disable CRL checking, you only need to
retrieve the CA certificate.
The CRL update period defines the interval at which the entity downloads CRLs from the CRL server. The
CRL update period setting manually configured on the device is prior to that carried in the CRLs.
