Crestron DM NVX Series Design Guide

Design Guide – DOC. 7977F DM NVX System • 17
A DM NVX device can have up to three addresses:
• The first address is required for control of the device and access to the web
configuration interface and console.
• Two additional addresses are required for multicast streams: one address for
the primary multicast stream of audio and video and another address for the
secondary audio multicast stream.
During endpoint configuration, the primary multicast address must be set
manually to an even-numbered IP address. The secondary audio multicast stream
address can be automatically assigned to a value of one higher than the primary
IP multicast stream address or can be manually set to the desired multicast
address.
The DM NVX network segment must receive network services, including DNS, DHCP,
Active Directory, and RADIUS services. Coordinate with IT staff to provide access to
these services and to create the proper traversal rules to the DM NVX network segment.
Network Segmentation along Logical Boundaries
Consideration must be given to blocking at both the switch level and the network
design level. DM NVX network switches must have enough switch fabric bandwidth to
support full nonblocking bidirectional gigabit bandwidth on all ports simultaneously.
This is a common feature in enterprise-grade gigabit network switches, but it should
not be assumed that a switch is nonblocking or is configured as nonblocking.
Due to system size or physical layout, most DM NVX installations require multiple
network switches. The network switches must connect to each other via a
high-bandwidth uplink port. For network design purposes, assume that each DM NVX
link consumes the full gigabit of link bandwidth.
Consider the example of a standard 48-port Gigabit Ethernet switch with one
40-gigabit uplink (or four 10-gigabit uplinks). Since each DM NVX endpoint consumes
1 gigabit of bandwidth, this switch can support up to 40 DM NVX devices in a
nonblocking way. If more devices are connected, the uplink becomes a bottleneck,
introducing the potential for difficult-to-diagnose blocking problems.
