Complete the First-Time Setup Worksheet

Before you begin system setup, fill out the applicable fields in the My System Values column of the following worksheet.

Network configuration of an appliance (hardware-based) RealPresence DMA system involves options and settings not relevant in a virtual deployment, including dual-server configuration and split management and signaling networks. Although those settings are present in the Network Settings page of the RealPresence DMA system's web-based user interface, they must not be used in a virtual deployment. They are clearly identified in the following worksheet.

Table 1. First-Time Setup Worksheet

Configuration Information

My System Values

Description

System IP type

Specify whether the system should support IPv4, IPv6, or both. If both, complete all the IP address information below. If only IPv4 or IPv6, complete only the corresponding fields below.

System server configuration

Specify whether you are installing a single-server system or a two-server system. For a single-server system, the Server 2 section below is not used.

If you received two servers, determine whether you're setting up a co-located two-server cluster or two separate single-server systems.

System split network setting

Specify whether to combine or split the system's management and signaling interfaces. If the same network will be used for both management (administrative access) and signaling, the signaling IP addresses and Shared Signaling Network Settings section below are not used.

Caution: Choose split networking only if you need to restrict access to the management interface and SNMP to users on an isolated non-public network separate from the enterprise network. Typically, this is the case only in high-security environments.

In most network environments, users accessing the management interface are on the same enterprise network as endpoints and other devices communicating with the system, and they use the same physical and virtual IP addresses and the same network interface.

To split the network configuration, you must use different gateways and subnets for management and signaling, and separate physical connections for the management and signaling networks.

If management and signaling traffic are combined on the same network (subnet), both use the same physical and virtual IP addresses and the same network interface.

If you are not sure whether split networking is appropriate, possible, or necessary for this installation, consult the appropriate IT staff or network administrator for your organization.

Server 1

Management host name

Local host name of the server's management interface.

Host names may contain only letters, numbers, and internal dashes (hyphens), and may not include a domain.

The host name is combined with the domain name specified under General System Network Settings to form the fully qualified domain name (FQDN).

Management IPv4

Static, physical IP address(es) for the first (or only) server's management (or combined) interface.

Management IPv6

Signaling IPv4

Static, physical IP address(es) for the first (or only) server's signaling interface (if networking is split).

Signaling IPv6

Server 2

Host name

Local host name of the second server's management (or combined) interface.

Host names may contain only letters, numbers, and internal dashes (hyphens), and may not include a domain.

The host name is combined with the domain name specified under General System Network Settings to form the fully qualified domain name (FQDN).

IPv4

Static, physical IP address(es) for the second server's management (or combined) interface.

IPv6

Signaling IPv4

Static, physical IP address(es) for the second server's signaling interface (if networking is split).

Signaling IPv6

Shared Management Network Settings

In the combined network configuration, users accessing the management interface are on the same network as endpoints and other devices communicating with the RealPresence DMA system, and these settings are used for both management and signaling.

Virtual host name

For a two-server system or a single-server system in IPv6-only mode, the local host name of the virtual management host. Not used for a single-server system with IPv4 enabled.

Host names may contain only letters, numbers, and internal dashes (hyphens), and may not include a domain.

The host name is combined with the domain name specified under General System Network Settings to form the fully qualified domain name (FQDN).

Virtual IPv4

For a single-server system in IPv6 only mode, the IP address(es) of the virtual management host. Not used for a single-server system with IPv4 enabled.

Virtual IPv6

IPv4 prefix length

IPv4 network mask that defines the subnetwork of the system's management interface.

IPv6 prefix length

IPv6 CIDR (Classless Inter-Domain Routing) prefix size value (the number of leading 1 bits in the routing prefix mask) that defines the subnetwork of the system's management interface.

IPv4 gateway

IP address of the gateway server used to route network traffic outside the subnet.

Management Link

The name of the network interface that will be used for management access.
Signaling LinkThe name of the network interface that will be used for signaling access.

Auto-negotiation

Yes or no. If no, indicate speed and full or half duplex.

Note: Auto-negotiation is required if your network is 1000Base-T.

LAN Security Settings

These settings are not used for Virtual Edition deployments.

Caution: In a network that requires 802.1x authentication for servers (this is rarely the case), incorrect settings in this section and, if applicable, lack of the proper certificate(s) can make the system unreachable. Recovering from this situation requires connecting a laptop to the system using a crossover cable in order to access it.

Enable 802.1x

Enables the system to authenticate this network interface to the LAN. Depending on the authentication method, the access credentials required may be either a user name and password (specified below) or a security certificate.

If you are deploying a Virtual Edition system, do not select Enable 802.1x.

User name

The user name with which the system may authenticate this interface.

Password

Confirm password

The password for the user name entered above.

EAP Method

The Extensible Authentication Protocol method used to establish trust with the authentication server (this is also known as the outer authentication protocol).

Protocol

When a TLS tunnel is established with the authentication server, the protocol used within the tunnel (this is also known as the inner authentication protocol).

Shared Signaling Network Settings

The settings in this section are enabled only if management and signaling traffic are on separate networks. If so, they apply to the entire system (both servers in two-server configuration).

For a one-server configuration, the virtual host name and IP fields are disabled.

General System Network Settings

DNS search domains

One or more fully qualified domain names, separated by commas or spaces. The system domain you enter below is added automatically, so you need not enter it.

DNS 1

IPaddresses of up to three domain name servers. At least one DNS server is required.

Your RealPresence DMA system must be accessible by its host name(s), not just its IP address(es), so you (or your DNS administrator) must create A and/or AAAA records for IPv4 and IPv6, respectively, as well as the corresponding PTR records, on your DNS server(s). A/AAAA records and PTR records that map each physical host name to the corresponding physical IP address and each virtual host name to the corresponding virtual IP address are mandatory, as are the corresponding PTR records that allow reverse DNS resolution of the system's physical or virtual host name(s).

DNS 2

DNS 3

Domain

The domain for the system. This is combined with the host name to form the fully qualified domain name (FQDN). For instance:

Host name: dma1

Domain: callservers.example.com

FQDN: dma1.callservers.example.com

Signaling DSCP

The Differentiated Services Code Point value (0 - 63) to put in the DS field of IP packet headers on outbound packets associated with signaling traffic.

The DSCP value is used to classify packets for quality of service (QoS) purposes. If you're not sure what value to use, leave the default of 0.

Management DSCP

The Differentiated Services Code Point value (0 - 63) to put in the DS field of IP packet headers on outbound packets associated with management traffic.

The DSCP value is used to classify packets for quality of service (QoS) purposes. If you're not sure what value to use, leave the default of 0.

Default IPv6 gateway

The IPv6 gateway's address, specified as:

<IPv6_address>

Default IPv4 gateway

The IPv4 gateway address.

System Time

In Virtual Edition deployments, some of the System Time settings are automatically configured as part of the installation process.

Time zone

Time zone in which the system is located. We strongly recommend selecting the time zone of a specific geographic location (such as America/Denver), not one of the generic GMT offsets (such as GMT+7).

If you do use a generic GMT offset (for instance, to prevent automatic daylight saving time adjustments), note that they use the Linux/Posix convention of specifying how many hours ahead of or behind local time GMT is. Thus, the generic equivalent of America/Denver (UTC-07:00) is GMT+07, not GMT-07.

NTP server #1

IP address of the primary NTP time server. Use of time servers is strongly recommended. All the devices in your video conferencing deployment should use the same time servers to avoid potential problems caused by time differences among devices.

NTP server #2

IP address of a second NTP time server (optional, but strongly recommended).

NTP server #3

IP address of a third NTP time server (optional, but strongly recommended).

Routing Configuration

Special routing rules are generally not needed.

If a static network route is needed, enter the values for the following fields.

If you are not sure if you need a static network route, consult the appropriate IT staff or network administrator for your organization.

Host/network

The IP address of the destination network host or segment.

Prefix length

The CIDR (Classless Inter-Domain Routing) value that, together with the destination host/network address, defines the subnet for this route.

For IPv4, a prefix length of 24 is equivalent to specifying a subnet mask of 255.255.255.0. A prefix length of 16 is equivalent to specifying a subnet mask of 255.255.0.0.

Interface

Specify the interface for this route.

Via

IP address of the next hop.
