Managing Network Traffic

Redundant network configurations can be employed, however, you must observe the
proper order of rear panel AT port connections. In redundant mode the 4-port switch acts
as two separate 2-port switches that duplicate audio traffic (see figure 87). The two sets of
switches (primary and secondary) cannot be connected together anywhere in the system.

Figure 87. AT Ports—Primary and Secondary Ports Configuration
At least two separate network systems are required for redundancy. The primary ports
(3 and 4) are connected to one network and the secondary (1 and 2) to another.
The redundant mode must be selected with Dante Controller (see
on page 119).
1. Launch Dante Controller
2. Access the Device View.
3. Double-click the device name from the
Routing View (see right,
4.
Select the Network Config tab (
5. In the Dante Redundancy panel, select
Redundant ( ) from the drop-down list.

The Dante Controller PC must always be
connected to one of the two primary ports on
the DMP 128 AT switch (see figure 87).
NOTES:
• In redundant mode, control information is carried only by primary ports 3 and 4. If a
control PC is connected running Dante Controller, it must use port 3 or port 4.
• AT connections follow the same distance limitations as standard Ethernet
connections.
• Potential issues of network flooding can occur. Check the Audinate Website
(www.audinate.com) for FAQs regarding managing network traffic.
Because Dante devices prefer to use multi-cast to distribute audio channels, it is
recommended that, if possible, the audio network be kept separate from the local business
network. For more information on strategies to manage audio network traffic in an integrated
system, refer to the Dante Controller manual (Multicast Transmit Flow Configuration).
