23-56 Polycom, Inc.
In compliance with UC APL requirements, PKI Self-signed Certificates are supported for the
both the Default Management and IP Network Services.
A mixture of Self-signed and CA-signed Certificates is supported, however a CA-signed
certificate will always override a Self-signed Certificate.
Self-signed Certificate Creation
Self-signed Certificates are created during:
• Initial system start-up before any CA-signed Certificates have been installed.
• IP Network Services creation.
• Network Services updates that result in Host Name changes.
• Daily validity checks of Self-signed Certificates.
• Backup and Restore of the system configuration
Self-signed Certificate field values are automatically inserted when the certificate is created:
