Polycom 3725-76302-001O manual Field Description

Local Cluster Configuration

Caution: Network Settings Changes Require a Restart

Changing some network settings (host names, IP addresses, or domains) requires a system restart and terminates all active conferences.

If the system is using a CA-provided identity certificate, changing some network settings (host names or IP addresses) also requires you to update the certificate. (If the system is using a self-signed certificate, an updated one is automatically created.)

You can’t change these network settings while the system is part of a supercluster or integrated with a Polycom RealPresence Resource Manager or CMA system. You must first leave the supercluster or terminate the integration. If the cluster is responsible for any territories (as primary or backup), reassign those territories. After the change, rejoin the supercluster or Polycom RealPresence Resource Manager or CMA system. See Superclustering on page 226 or Resource Management System Integration on page 178.

Incorrect network information may make the system unusable and the management interface unreachable.

Caution: Configuring the RealPresence DMA System in a Secure Environment

The 802.1x LAN security settings can’t be configured in the USB Configuration Utility. In a highly secure network that requires 802.1x authentication, the Polycom RealPresence DMA system won’t be accessible until those settings are properly configured. To do so, follow the procedure for configuring the network settings using a laptop, as described in the Deployment Guide for Maximum Security Environments.

Note: Virtual Host Name Not Needed for Single-Server Systems

This version of the Polycom RealPresence DMA system eliminates the need for virtual host name(s) and IP addresses in a single-server system or cluster. When a version 5.0 or earlier single-server RealPresence DMA system is upgraded to version 5.1 or later, the previous version's virtual host name(s) and IP addresses become the upgraded version's physical host name(s) and IP addresses, so accessing the system doesn't change.

(Exception: If only IPv6 is enabled, the system must have two addresses, so a single-server system must still have a virtual host name and IP address.)

Field	Description
System IP type	IP addressing supported (IPv4, IPv6, or both).
System server configuration	Number of servers (1 or 2) in this cluster.
	Caution: Once this is set to 2 server configuration, it can’t be changed back
	to 1 server configuration. To reconfigure a two-server system as two
	separate single-server systems, you must use the USB Configuration Utility.
	See the Polycom RealPresence DMA 7000 System Getting Started Guide.
