# Dante Optimization Settings

### 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 speakers) included in ADECIA systems.

LLDP

Protocol for passing device information to neighboring devices.

### 3. Function Details

Dante settings can be optimized by the following two methods.

- Automatic optimization settings using LLDP

  - Automatically applies optimized settings by receiving LLDP frames independently from ADECIA components.

- Manual optimization settings via the Web GUI

  - Apply a Dante profile from the ProAV settings page in the web GUI of this product.

The settings that can be collectively specified at the same time using the Dante setting optimization function are listed below. For automatic setting optimization using LLDP, the applicable settings will differ depending on the ADECIA component firmware version.

Use the Dante optimization setting function after you have made all of the basic switch settings (such as VLAN and IP).
If you make new changes to the settings, the Dante optimization settings will not follow.

#### 3.1. Automatic optimization settings using LLDP

Settings optimized for Dante can be applied automatically by receiving LLDP frames created independently by ADECIA components.

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.

If this function is enabled and an LLDP frame is received from an ADECIA component, 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.
In ADECIA V2.8 or the later version, 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.

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.

#### 3.2. Manual optimization settings via the Web GUI

Apply a Dante profile from the [ProAV settings] - [ProAV profile] pages in the web GUI of this product.
For details, refer to ProAV Settings.

### 6. Points of Caution

- It is assumed that you will use the Dante optimization setting function after you have made all of the basic switch settings (such as VLAN and IP).
  If you make new changes to the settings (such as adding a VLAN), the Dante optimization settings will not follow.

- Manual optimization settings via the Web GUI

  - Note that if you use this function when settings such as QoS settings, flow control settings, EEE settings, and IGMP snooping have already been made, those settings are overwritten by Dante-optimized settings.

- Using LLDP to specify settings automatically

  - This function can be used only for a physical interface (LAN/SFP port). It cannot be used with a link aggregated logical interface.

  - LAN/SFP port modes can only be used at access ports. They cannot be used at trunk ports.

  - In ADECIA V2.8 or the later version, the function is disabled if even one of the automatically specified settings differs from factory settings.
