(5) [Delete Certificate]
Deletes all installed CA certificates, client certificates,
and client private keys.
Only "CA Certificate" is displayed when
[Authentication Method] is set to [EAP-TTLS] or [EAP-
PEAP], but any installed client certificates and client
private keys are also deleted.
Important
• If any CA certificates, client certificates, and client private
keys already exist, they are discarded and new versions are
installed.
• An error occurs if the format of the certificate or private key to
be installed is incorrect.
• Client certificates and client private keys are checked as a
pair when installing, and an error occurs if they do not match.
• The certificate and private key used for 802.1X authentication
must be installed as separate items, irrespective of the
installation status of certificates for SSL/TLS.
