Tesira 3.11 FW (and later)addedsupport for Dante Domain Manager(DDM) on all Dante-capable Tesira devices. EEE reduces device power consumption when network traffic is low. Note that the Dante card will always indicate its total number of channels(32 or 64) in Controller. Audinate refers to any hardware running on pre-4.0 Dante FW as a legacy device. For example, a system may have a device that is periodically connected and disconnected, e.g., an input to the network from a stage box or mixing console. PDF Download Basically, what you need to know is that Dante is all IP-based, and makes use of common IT standards. In systems with TC-5, TC-5D, orTesiraFORTX certain network topologies may be put in place which block neededmulticast messages from getting through to Dante endpoints. Creating a basic Dante network, discovering, and routing signals with Dante Controller, Dante devices, and a network switch. In the professional environment, meticulous care is usually taken to ensure that the Dante switches and connections are only used for Dante devices. To force a specific device to become the Master Clock you would normally use the Dante Controller to set a Dante device to be "Preferred Master". Packet control features such as VLANs and IGMP snooping. Unlike CobraNet and AVB, Dante provides per-channel routing, so each Dante receiving channel (within an Input block) can conceivably come from a different Dante-enabled device. With a primary focus on Q-SYS audio, video & control (AV&C), these network switches provide an out-of-the-box solution for Q-SYS . If the Master Clock fails for any reason, a new Master Clock will be chosen from the existing slaves within a few seconds. The table below shows how Dante hardware devices apply DSCP packet priority values: Each DAN-1 card can transmit up to 64 channels of audio and receive up to 64 channels of audio (64x64) in up to 32x32 flows. NS Series Network Switches - Networking - Products - QSC - Q-SYS For lower channel count (<32) applications, a 100Mbps switch may be used as long as it supports proper . Dante allows you to configure low latency connections for critical audio paths, while at the same time running higher latency connections for a broadcast or recording feed where latency is less critical. Legacy Dante devices (running pre-4.0 Dante FW) in one subnet cannot act as a boundary device to talk or listen directly to a Dante device in another subnet. To create multicast flows the transmitterbit depth must be changed to match that of thereceivers. The TesiraFORT DANcan have 32 x 32 simultaneous flows, with a total of 32x 32channels. Only one device per Dante networkmay be defined asbothPreferredMaster and Enable syncto external" in order to avoid conflicting clocks. Capable of switching off Energy Efficient Ethernet (EEE) and other power-saving features 3. What is the minimum requirement for switches in a Dante network? This is equivalent to a forwarding rate for the entire switch of 1.4 Mpps the number of ports. the Dante Virtual Soundcard) may need to use higher latency to reliably process high channel counts. QoS is also recommended for Gigabit switches on networks that share data with services other than Dante. Each TesiraFORT DANcan transmit up to 32channels of audio and receive up to 32 channels of audio (32x32) in up to 32x32 flows. QoS is recommended for Gigabit switches on networks that share data with services other than Dante. Audinate Dante port requirements can be found here, Additional Audinate Dante network requirements can be found at, Audinate Dante Domain Manager has additional network requirements which can be reviewed here. We're generally using Cisco SG250 w/POE + # of ports required, but I wanted to see if anyone had any better/quicker suggestions. "Enable sync to external" indicates that the device is connected to multiple clock sources and prefers to be synced toanother clock domain, itis then imposing this clock onthe Dante network. There are usually separate networks for transferring files between a PC and server or the Internet. How does Dante use DSCP / Diffserv priority values when - Audinate 2. The beauty of a DHCP server is that you can define a specific address range for the automatic address allocation. We highly recommend that you use switches that support DiffServ (DSCP) QoS with strict priority and 4 queues. With the Aruba 2530, for example, VLANs can be set up and the ports assigned via the web browser. The Biamp DAN-1 card supports 1 ms and 2 ms latency. The DAN-1 Dante network should not share the same network hardware as AVB or CobraNet devices. For more information about multicasting, IGMP snooping, and how to configure these features, see Setting up a Network Switch later in this guide. TesiraDante I/O channel blocks each represent a subset of that total number of channels. Attempting to directly load Audinate firmware to a DAN-1 or FORT DAN Dante endpoint using Dante Controller or other means may corrupt the endpoint and render it inoperable. To help manage the multicast traffic on the network it is often recommended to enable IGMP snooping on your switches. Dante Domain Manager(DDM) is a virtual appliance which enablesthefunctionsdescribedabove. Multicast flows are encoded at the current setting of the transmit device and will not connect to devices running at a lower bit-depth. Critical Note: Proper MXW operation is obtained only when using a properly configured managed Gigabit Ethernet switch. The TesiraCONNECT TC-5D can have 32 x 32 simultaneous flows, with a total of 32x 32channels. If video is present, follow the additional instructions at the end of this document and ensure all links to child switches are set to forward the Dante traffic. Device View indicates all crosspoints in the Receivetab. Devices should be updated to Biamp FW 3.11 or later. The problem with unmanaged switches: due to the lack of a web interface, no changes can be made to the switch. I would be more concerned about the 1G switches with multiple NDI streams. Adding new devices to a network does not affect the latency of devices already in the network. The old PoE standard offers 15 watts per port, the new PoE+ gives you 25 watts. There are two criteria to look out for: For a few devices or a few Dante channels, ports with 100Mbit/s are sufficient in terms of transmission speed. The Dante device with the highest quality Dante chipset and lowest MAC address will become the "Preferred Master". A sufficient forwarding rate is 1.4 Mpps per port (gigabit). Configuring a Switch for Dante - Focusrite Audio Engineering Audio can be routedbetween subnets by Dante hardware runningFW 4.0 and higher. - A multicast flow can not be established between a 32-bit transmitterand multiple 24-bit receivers. We recommend managed (intelligent) switches that can be configured and monitored. A unicastflow is a standard container for up to 4 channels which is created automatically when you configure Dante routing between 2 devices. Are the Dante networks for primary and secondary built up as a common network and can both networks share uplinks in the event of an accident? If youplace (4) 8-channel Dante input blocks in a configuration the Tesira compiler will allocate those blocks to the Dante card in the order it sees as the best solution at that time - a different solution may be found the next time. This is normal operation. e.g. The device will not be renamed. TheTesira'sDAN-1 cards, TesiraFORT DAN, TesiraFORTX, and TesiraCONNECTTC-5D only run Dante firmware provided byBiamp via Tesira firmware updates. Biamp offers 2 TesiraDante solutions, the DAN-1 card for the Server and Server-I, Installing a virtual Asterisk VoIP server, Naming Dante channels and devices in Tesira, Set Dante IO blocks "Fixed in unit" option toTrue, TesiraFORT X 400, TesiraFORT X 800, andTesiraFORT X 1600, https://www.audinate.com/resources/training-and-tutorials, Dante Level 1,Level 2, and Level 3 certifications, https://www.audinate.com/faq/which-network-ports-does-dante-use, https://www.audinate.com/sites/default/files/PDF/adding-dante-to-your-network-audinate.pdf, https://dev.audinate.com/GA/ddm/technical-notes/network-admin/pdf/latest/DDM%20-%20Info%20for%20Network%20Administrators%20v1.9.pdf. This regularly asks all hosts in the network who wants to receive which multicast stream. 23 Reply [deleted] 2 yr. ago [removed] Reply talones 2 yr. ago Dante redundancy requires that both the primary and secondary interfaces on any redundant device are connected using the same link speed. A few pointers to consider: Are usually more than 100 Dante channels in use (input signals to the mixer, signals from the mixer to the DSP, signals from the DSP to the amplifiers / speakers, possibly signals for recording)? If you intend to multicast over multiple switches, you will also need to configure multicast router ports. And of course there are also switches with redundant power supplies that can be exchanged during operation (hot-swappable). Audio data is transmitted on both the primary and secondary networks simultaneously. for more details. You don't have to memorize any commands and all options are clearly displayed. Failure to set all Dante blocks to beFixed in unit = True may result in subscription errors or corruptchannel routing assignments if Tesira DSP files are updated after routing has been done in Dante Controller. In the theater there is usually always a time window between rehearsal and performance where you can turn off the switch completely for an hour and replace the power supply. The latency of hardware devices does not depend on the number of audio channels routed, however some devices (e.g. TesiraFORT Xoffers a virtualized Dante endpoint hosted in the TesiraFORT Xnetwork appliance. For Tesira Dante hardware, names may be assigned to channels and devices only from Tesira software. Although Dante packet priority values have been chosen to make it simple to configure QoS with many switches, some switches require special configuration to recognize and prioritize specific DSCP values. Network Switches - QSC Audio Products Only channels which have associated I/O blocks in the Tesira DSP will have their channels names populated. And MSTP can be used to configure several Spanning Tree instances (which each uses RSTP) so that a different root bridge can be defined for each VLAN, in our case for the primary and secondary network. An external clock source which is internally connected to the Dante device (e.g. With multiple connections, data packets would always be sent in a circle and the network would become overloaded and unstable. In larger installations, multiple switches will be needed. The Q-SYS NS Series Gen 2 offers a range of enterprise-grade, NETGEAR-manufactured network switches that have been pre-configured specifically to meet the performance requirements for Q-SYS, AES67 and Dante. Selecting Network Switches. Latency can be configured to be different between different devices in the same network, and does not have to be the same for all connections on the network. Before we take a look at the most common functions that we find in the marketing brochures of various manufacturers, I would like to point out that in addition to the content-related features, there are of course also purely material aspects. For low channel count (<32) applications, a 100Mbps switch may be used as long as it supports proper QoS, and QoS is active. Automatically generated TesiraDantehostnameswill be unique per device, following the convention: As with channel names, the device names can be changed to better reflect the use case associated with the device. Most switches offer both, but unfortunately occasionally with a different range of functions. Both switches are available in PoE and PoE+ variants. Biamp maintains a firmware library for Tesiraproducts. Since Tesira's clock protocol requires it to be the Master Clock for the system (when AVB is selected as Network Media clock master) this scenario will cause a (major) system fault. In such a case, multicast will not reduce the number of flows, so its necessary to reconsider the routing itself. The user sets this latency with Dante Controller and the value selected should be based upon the size of the network. The point is negligible for installation in server racks and closed amplifier rooms far away from your usual workplace. Tesira devices have a processor hostname for Tesira software and a Dante hostname for the Audinate Dante interface. By configuring the QoS settings recommended by Dante on a network switch, you can give Dante clock synchronization top priority and give audio data the next highest priority over background data traffic. - a Dante microphone using 1 flow containing 1 channel) the number of flows will limit the number of connected devices before the DAN-1's 64 channel maximum is reached. A flow is a container Dante uses automatically to encapsulate 1-4 channels for transmission. Setup a Cisco SG300 / 500 switch for Dante | technet - Genesis Technologies Any switch that supports Diffserv (SCP) QoS with strict priority and four queues, and which has Gigabit ports for inter-switch connections should be appropriate for use with Dante. Quality of Service (QoS) refers to technology for prioritizing the transfer of specific data. Furthermore there are some switches mentioned on this Shure website that are NOT recommended for Dante application. And you could let the DHCP server allocate addresses only in the range 192.168.10.201-250 for mobile devices. Tesira software only allows unconfiguredTesira hardware to be renamed. The Dante card is always updated as a unit, so an update to a subset of its channels requires an update to the entire card. Output channels will be allocated in the same manner, beginning withOUT1_1and so on. When a switch has IGMP snooping and filtering turned on, it will prevent IP multicast from flooding the network. Attempting to load Dante firmware directly to the Dante cards via Dante Controller or Audinate's Firmware Update Manager may result in an unrecoverable device. Open Shure Web Device Discovery. "DeviceLockallows you tolockand unlocksupported Dante devices using a 4-digit PIN (Personal Identification Number). The number of channels that can traverse one link in a network is proportional to the link speed. To check whether all the ports are capable of simultaneous gigabit transfer (whether the switch is non-blocking), determine whether the switching capacity is at least 1 Gbps the number of ports 2 (for in and out). When connected to an IP/Ethernet network, a Dante-enabled device will automatically configure its own IP address and advertise itself to other devices on the network. This is sufficient for a very large network, consisting of a Gigabit network core (with up to 10 hops between edge switches) and 100 megabit links to Dante devices. The DAN-1 card connects via standard CAT-5e or higher network cabling to a network switch. But for a few devices per location you are much more flexible if you can use a switch twice through several VLANs. I have made a detailed comparison of these in this blog post. Channel names, bit depth, and other options should not be recalled as these can cause routing issues. Networking details Network switch requirements Firmware Update Manager Dante is a proprietary digital media networking solution, developed by Audinate and licensed by Biamp, which operates on 100Mbps and Gigabit networks using standard Internet Protocol (IP) over Ethernet. But as soon as you get to the points that are not unimportant for Dante, such as QoS or MSTP, you can no longer continue without the command line. When names are applied from Dante Controller software they will not persist through a power cycle, reboot, or configuration update in Tesira as they are not part of the Tesira DSP configuration file. In this respect, it is understandable that redundant power supplies are rarely found in theater systems at the moment. What is the minimum requirement for switches in a Dante network? When using multicast flows, the traffic for all ports inevitably increases, because the recipient sends a multicast packet to all devices in the network at the same time. The Dante card itself is either a 32x32 (FORT DAN) or 64x64 (DAN-1) device. The Preferred Master checkbox in Dante Controller will clear itself if it is selected. 1Gbit is recommended in any case, and with a high number of channels, 10Gbit between the switches. are other networks / VLANs being considered besides Dante, for example networks for controlling devices, for transferring files to the server, for the Internet or for communication (intercom stations)? To configure alocked device you must first unlockit using the PIN with which it waslocked.". This is because after you configure one switch, you can copy the settings of that switch to the other switches. Altering the default encoding bit-depth may be required when sending multicast flows to devices which are limited to lower bit-depths. This device may not be always present and thus would be a poor choice for a Master Clock. Because the actual features that a switch brings with it in the upper class are hardly used in everyday audio. Tesira with Dante only, or CobraNet and Dante: If a device set as a Preferred Master is added to a Tesira Dante system, and that device's Dante MAC address is lower than that of the Tesira Server, it will become the Master Clock device. Capable of switching off Energy Efficient Ethernet (EEE) and other power-saving features. This is managed on a per block basis on Dante input and output blocks in Tesira software by checking or unchecking the 'Fault when inactive' option in the block's initialization dialog. If you dial into a foreign WLAN with your mobile phone, it goes without saying that you get your IP address from a DHCP server and don't have to worry about anything else. There is no supported method for updating the Dante firmware independent of the Tesirafirmware update. #2:64 input channels to one DAN-1 from (16)4-channel Dante wall plates would be automatically encapsulated within (16)unicast flows containing 4channels each. The names denote which block and channel within the block is associated with a given stream on a given device. Make sure that EEE is disabled on all ports used for real-time Dante traffic. Unicodeand non-roman characters are not supported. Pre-4.2 Dante devices, including Tesira, can participate in domains with Dante 4.2 devices using AES67 or SMPTE. Dante Information for Network Administrators (PDF) Dante Clock Election Chart (PDF) Dante Networks and EEE Switches (PDF) Cisco Switch Configuration Guide (PDF) - September 2022. Users arestronglydiscouraged from editing Tesira transmit and receive channel or device names usingDante Controllersoftware, as the updated names will not be transmitted back upstream to theTesirasoftware and will be overwrittenwith the names from the Tesira file when a device reboots. Be sure to save a copy of the site file once channel names have updated. AES67-enabledDante devices use Dante flows when sharing audio with other AES67-enabled Dante devices. This is still more than enough in most homes. You only have to consider how much power the Dante devices require. AES67-FAQ | Media Networking Alliance This information includes the quality of its clock, clock source, link speed and other parameters, and results in the best clock being elected as the Master Clock. Further information regarding device specific channel and flow countscan be found here. Be careful to keep the number of multicast flows (channels) to a minimum, because multicast flows increase the load that the network is subjected to. Last but not least, here is the already shown overview table with a few current switch models as a small summary, without guarantee: I hope I was able to provide you with a few criteria for your next Switch purchase. e.g. The Quality of Service (QoS) technology allows the data packets to be prioritized. Each TesiraCONNECTTC-5Dcan transmit up to 32channels of audio and receive up to 32 channels of audio (32x32) in up to 32x32 flows. The fault can be resolved by unchecking the Preferred Master selection for the offending device or by setting Dante as Tesira's Network Media clock master (in the Tesira configuration file). If these higher priority clock sources are present then Tesira's clock will sync to their clocks. Unless you are using Dante devices that can be daisy chained, you will need a network switch that meets the fo requirements to construct a Dante network. Each DAN-1 card can transmit up to 64 channels of audio and receive up to 64 channels of audio using up to 32 flows in each direction. In my opinion, IGMP snooping is absolutely necessary for larger applications and is fortunately supported by most switches. Updating firmware on a Biamp Tesira Dante endpoint is done by updating the Tesira device's firmware. This may cause EEE to be enabled in Dante networks when it is not appropriate, resulting in poor synchronization performance and occasional dropouts. A number of Dante devices only have a 100 Mbit port and are therefore overloaded as soon as the multicast load in the network increases (100 Mbit are reached at around 50 Dante channels). Capable of switching off Energy Efficient Ethernet (EEE) and other power-saving features. 48 x 48 48kHz/24bit audio channels can be sent over a single link, giving a total of 96 bi-directional channels. Favorite Dante switches Hello fellow AV nerds What switch (s) are you guys liking for quick setup (during install) for standalone Dante systems? In Europe, multimode fiber optic cables are mostly used, but there are also houses with singlemode fiber optic cabling. This means that a Dante recipient only receives those Dante flows that it has actually ordered. Biamp Dante firmware updates are embedded in the Biamp Tesira firmware package and can only be appliedusingBiamp Tesirasoftware's Device Maintenance > Update Firmware tool. Without questioning queriers, there are no IGMP messages, so nothing to listen to and the whole system does not work. If hops greater than 100 meters are necessary you can use fiber optic cabling. Dante clocking guarantees that all devices are synchronized to within 1 microsecond or less, and that all devices can play out audio at the level of sample accuracy. Not all Dante devices need to be 4.2 in a SMPTE domain but, naturally, only the devices that support SMPTE will be able to receive SMPTE flows. IGMP snooping may even be implemented differently in different switch families from the same manufacturer. #2:32 output channels from one TesiraFORT DAN to (16) 2-channel output wall plates would be automatically encapsulated within (16)unicast flows containing 2 channels each. Article #1770518 Updated on Sep 21, 2022 at 1:23 PM In this guide, we will explain what Dante is, how it works, and how to get set up and connected for the first time. But there are many features that make management much easier in situations with several switches and allow the existing cable infrastructure to be used more efficiently and safely. Sure. A Tesira with both AVB and Dantecards is not required to be a "Preferred Master" device. TesiraFORT Xcan host both AVB and Dante I/O blocks, allowing new options for incorporatingTesiraAVB and Dante in a Tesira system.
