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 71). The two
sets of switches (primary and secondary) cannot be connected together anywhere in the
system.

Figure 71. 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
Controller on page 118).
1. Launch Dante Controller
2. Access the Device View .
3. Double-click the device name from the
Routing View.
4. Select the Network Config tab.
5. In the Dante Redundancy section,
from the
New
Redundant.
The Dante Controller PC must always be connected to one of the two primary ports on
the DMP 128 AT switch (see figure 71).
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).
