Dante Optimization Setting Function

1. Function Overview

The Dante setting optimization function makes it easy to build the optimal environment for “Dante” digital audio networks.
The function allows users to easily configure all Dante settings at the same time without having to think about individual Dante settings (such as QoS, IGMP snooping, disable flow control, and disable EEE settings).

2. Definition of Terms Used

Dante
Dante is a digital audio network specification developed by the Audinate Corporation.
ADECIA
ADECIA is Yamaha’s teleconferencing system. It connects processors, microphones, and speakers used for teleconferencing via a LAN (Dante).
ADECIA Components
Devices (teleconferencing processors, microphones, and speaker system) included in ADECIA systems.
LLDP
Protocol for passing device information to neighboring devices.

3. Function Details

Dante settings can be optimized by the following three methods.

  • Automatic optimization settings using LLDP

    • Optimized settings are automatically applied by receiving proprietary LLDP frames from ADECIA components.

  • Manual optimization settings via the Web GUI

    • Optimized settings are applied from the ProAV settings page indicated in the web GUI of this product. For information on how to apply the settings using the web GUI, refer to the ProAV setting function.

  • Preset settings using DIP switches

    • The settings are applied by setting the DIP switches on the back of this product to a Dante preset and starting the product. For instructions on how to set the preset using the DIP switches, see Presets.

The following explains the details on automatic optimization settings using LLDP.

This product automatically reflects the settings optimal for using “Dante” by using the proprietary LLDP frames received from ADECIA components.
The items that are automatically set vary depending on the firmware version of the connected ADECIA component. The list of setting items is shown below.

Automatic optimization settings via LLDP are set by the lldp auto-setting command.
By default, this product is set to enable automatic optimization settings via LLDP.

ADECIA components transmit Yamaha-proprietary LLDP frames that contain the following contents.

  • EEE (Energy-Efficient Ethernet) disable setting

  • Flow control disable setting

  • Diffserve base QoS setting

  • IGMP snooping settings

If this function is enabled and a corresponding LLDP frame is received, then the settings are automatically applied to the running-config settings for the overall system, for the VLAN interface that received the frame, and for the LAN/SFP port where the LLDP frame was received.
However, the function is disabled if even one of the automatically specified settings differs from factory settings.

If you save using the copy running-config startup-config command or the write command, the settings are also applied to the startup-config that is used for the next and subsequent startups.

Even if the port to which the device is connected experiences a link-down state after automatic optimization settings, the automatically added settings are maintained.

This function can be used only for a physical interface (LAN/SFP port). It cannot be used with a link aggregated logical interface.
In addition, LAN/SFP port modes can only be used at access ports. They cannot be used at trunk ports.
This function cannot be used if the stack function is enabled on models that support it.

In order to use this function, reception of LLDP frames must be enabled.
For this reason, check in advance that the following settings have been made.

  • Enable LLDP functionality for the overall system using the lldp run command.

  • Create LLDP agents at applicable interfaces using the lldp-agent command.

  • Specify the LLDP frame transmit/receive mode using the set lldp command.

LLDP frame transmission and reception are enabled in product default settings.
