Introduction

Due to the network requirements established by Audinate® for Dante™ Networks and considering the network requirements for Ecler VEO over IP devices, this quick guide explains how to configure the D-Link DGS-1210 family of switches to comply with these requirements. All requirements are mandatory for every switch used in a Dante or VEO over IP system, regardless of the brands.

Establishing Communication with D-Link Ethernet Switch

1. Connect your computer to the D-Link Ethernet Switch using an Ethernet cable. D-Link DGS-1210 Ethernet Switches come with a default Static IP address of 10.90.90.90.
2. Configure your PC with a Static IP address in the same subnet, such as 10.90.90.66, with a subnet mask of 255.0.0.0.
3. Open your Internet browser and type the default IP address of the switch: http://10.90.90.90. The default Password is “admin”.

Enabling IGMP Protocol

Internet Group Management Protocol (IGMP) is mandatory for the correct operation of VEO over IP products when configured as multicast devices. Without IGMP enabled, audio/video signals may not transmit properly or may freeze. With IGMP snooping, the Smart Managed Switch can make intelligent multicast forwarding decisions by examining the content of each frame's Layer 2 MAC header. IGMP snooping helps reduce cluttered traffic on the LAN. When IGMP snooping is enabled, the Smart Managed Switch forwards multicast traffic only to connections that have group members attached.

Steps:

1. Select L2 Function → Multicast → IGMP Snooping from the switch's navigation menu.
2. Enable IGMP Snooping by activating the related selection box and clicking on Apply.

Description of IGMP Snooping Configuration UI: The D-Link switch interface displays the 'IGMP Snooping Configuration' panel. Users can configure 'IGMP Snooping Global Settings' such as Host Timeout, Robustness Variable, and Query Interval. Options to enable/disable IGMP Snooping and report to all ports are available. A 'Safeguard' section and an 'Apply' button are also present.

Enabling Jumbo Frame

D-Link Gigabit Smart Managed Switches support jumbo frames (frames larger than the Ethernet frame size of 1536 bytes) of up to 9216 bytes (tagged). This feature is disabled by default.

Steps:

1. Select L2 Function → Jumbo Frame from the switch's navigation menu.
2. Enable Jumbo Frame by activating the related selection box and click on Apply.

Description of Jumbo Frame Settings UI: The 'Jumbo Frame Settings' interface allows users to enable or disable the Jumbo Frame feature. The maximum length is indicated as 10000 bytes. An 'Apply' button is available.

Disabling Power Saving and EEE (Energy Efficient Ethernet)

To prevent audio or video drops, all power saving features must be disabled. This is a mandatory requirement for Dante™ Networks.

Steps:

1. Select System → Power Saving from the switch's navigation menu.
2. On Global Settings, disable Cable Length Detection/Link Status Detection and press Apply.
3. Select IEEE802.3az EEE settings and ensure that the feature is disabled on the ports where Dante or VEO devices are connected.

Description of Power Saving Settings UI: The 'Power Saving Settings' interface provides 'Global Settings' where users can disable 'Cable Length Detection/Link Status Detection'. An 'Apply' button is present.

Description of IEEE802.3az EEE settings UI: The 'IEEE802.3az EEE settings' interface allows configuring the state (Enabled/Disabled) for EEE on specific ports.

Creating VLANs for Dante™, Video over IP and Control Coexistence

In AV systems where Dante™ and Video over IP traffic share the same network switch, VLANs are highly recommended because Video over IP could interfere with Dante™ in the same network. A VLAN allows isolating network traffic of a predefined group of ports. For Audio and Video systems, two VLANs are needed: one for Audio and one for Video. In this scenario, a device connected to the Audio VLAN cannot communicate with a device connected to the Video VLAN. When a control device (like a touch panel) is required, it needs to communicate with both Audio and Video devices. For this, an Asymmetric VLAN feature is used, which allows sharing traffic between different VLANs only on predefined ports.

In the following example (Fig. 1) we have:

• MIMO4040DN matrix with Dante™ (Control on port 1; Dante on port 2)
• WPNETTOUCH (Control on port 3)
• DN404BOB (Dante/Control on port 5)
• VEO-XTI2L (Video/Control on port 15)
• VEO-XRI2L (Video/Control on port 16)
• VEO-XRI2L (Video/Control on port 17)

We need to create 2 VLANs as follows:

• 1 Audio/Control VLAN (default): Ports 1-14
• 2 Video/Control VLAN: Ports 15-28

Description of Fig. 1 Diagram: Figure 1 illustrates the network topology. It shows the D-Link DGS-1210-24P switch connected to various Ecler devices: MIMO4040DN (ports 1-2), WPNETTOUCH (port 3), DN404BOB (port 5), VEO-XTI2L (port 15), and VEO-XRI2L (ports 16-17). Port assignments for Dante, Video, and Control traffic are indicated.

Steps:

1. Select VLAN → 802.1Q VLAN from the switch's navigation menu, enable Asymmetric VLAN, and click on Apply.
2. Click on the VID Settings tab. For VLAN 1 (default), mark ports 1-14 as Untagged. Add ports 16-17 for Control sharing. Click on the Apply button.
3. Create a second VLAN for Video/Control by clicking on the Add button.
4. Assign 2 as VID, and Video as Name to the new VLAN. Mark as Untagged all the Video/Control VLAN ports (15-28), adding the Audio/Control VLAN ports that need to share Control traffic (1-3). Click on the Apply button.

Description of 802.1Q Asymmetric VLAN Settings UI: This interface allows enabling or disabling Asymmetric VLAN functionality and lists existing VLAN entries.

Description of VID Settings UI: This section displays VLAN ID (VID), VLAN Name, and port configurations (Untagged, Tagged, Not Member) for each port, allowing users to select ports and their roles within each VLAN.

Description of Save Configuration UI: The 'Save Configuration' panel prompts users to save the current device configuration, typically by clicking a 'Save Config' button.
