PTP transparent mode

Hi @Mar344,

The Zyxel XS1930 series switches do support functionalities relevant to AV applications and PTP.

• The XS1930 series, along with other Zyxel Networked AV switch models, is designed to support AV over IP (layer 3 license required).
• Zyxel switches, including the XS1930, support Precision Time Protocol Version 2 (PTPv2) by allowing you to manually add PTP multicast addresses using Static Multicast Forwarding by MAC or IP. This involves configuring specific PTP multicast IP or MAC addresses (e.g., 224.0.1.129 for PTP-1 or 01:00:5e:00:01:81 for PTP-1) within the switch's settings.
• A new firmware version 4.90 optimizes the Networked AV Wizard to enhance multicast handling for AV protocols like Dante, which rely on precise timing and PTP events. This optimization includes automated DSCP priority settings for PTP events (DSCP 56) and automatic MAC and IP address configuration for multicast groups related to PTP traffic. This feature helps improve performance in AV streaming environments by forwarding traffic only to relevant devices.

For optimal AV over IP performance, Zyxel generally recommends using standalone mode for Dante applications, as some advanced features required for Dante might not be fully supported in Nebula.

To assist you further, please provide the following information:

• Device Model: (e.g., XS1930-10, XS1930-12HP)
• Firmware Version: You can find this in the switch's web GUI under "SYSTEM" > "General Setup" if your firmware is V4.80, or "Basic Setting" > "General Setup" if V4.70.
• Network Topology Map: A diagram showing how your XS1930 switches are connected to your AV equipment and other network devices.
• Specific Error Messages or Symptoms: If you are encountering any issues, please provide screenshots or detailed descriptions.
