Note

  • If you install your own server certificate to use with the EFA HTTPS server, ensure to reinstall the certificate when you upgrade EFA.
  • Generate the third-party certificates and keys without a passphrase. Certificate installation may fail if you generate the third-party certificates and keys with passphrase.
  • Ensure that the certificate that is uploaded has validity of at least 90 days.
  • EFA relies on common name and SAN IPs of the certificate. For a single-node deployment, SAN IP field must have the management IP of the system. In multi-node deployment, ensure that the node IPs and the VIP are present.
  • If there are any multiaccess subinterfaces, ensure to add these IPs to the SAN IPs when you generate a certificate.

Location
