The Best Network Switches for Dante and AoIP

Dante and other AoIP protocols place strict demands on network infrastructure. A switch must support three core features: a non-blocking backplane, Quality of Service (QoS) with DiffServ prioritization, and IGMP snooping. Without these, audio packets can collide, be delayed, or be dropped entirely.

A non-blocking backplane ensures that every port can operate at full wire speed simultaneously. For a 48-port gigabit switch, this means a switching capacity of at least 96 Gbps (bidirectional). This prevents bottlenecks when multiple audio streams are routed through the same switch.

QoS with DiffServ marking allows the switch to prioritize time-sensitive audio traffic over other data. Dante uses DSCP (Differentiated Services Code Point) values 46 for audio and 34 for control. The switch must be configured to trust these markings and place audio packets in the highest-priority queue.

IGMP snooping is essential for multicast Dante streams. It prevents audio traffic from flooding all ports by intelligently forwarding multicast packets only to ports that have requested them. Without IGMP snooping, a single Dante stream can saturate the entire network.

Gigabit Ethernet is mandatory. While Dante can run on 100 Mbps, modern systems with 96 kHz, 32-bit audio and many channels quickly exceed that. All ports should be gigabit (1000BASE-T) or higher.

Energy-Efficient Ethernet (EEE, 802.3az) must be disabled. EEE can introduce latency and jitter by putting ports into low-power sleep states. Most managed switches allow EEE to be turned off per port or globally.

PoE (Power over Ethernet) is optional but highly useful for powering Dante-enabled microphones, speakers, or stage boxes. Ensure the switch provides sufficient PoE budget (e.g., 802.3at or 802.3bt) for your devices.

Fibre uplinks are valuable for long-distance runs between stages, FOH, or distributed systems. SFP+ ports supporting 1G or 10G fibre allow clean, electrically isolated connections over hundreds of meters.

Unmanaged switches are plug-and-play but lack the controls needed for reliable Dante operation. They cannot disable EEE, configure QoS, or enable IGMP snooping. For small, simple systems (fewer than 30 devices on a single subnet), an unmanaged switch may work, but it is not recommended for mission-critical or large-scale installations.

Managed switches give you full control. You can disable EEE, set up QoS with strict priority queues, enable IGMP snooping, and configure VLANs to separate audio traffic from other network traffic. Managed switches also provide port statistics and SNMP monitoring for troubleshooting.

For any system with more than a handful of devices, a managed switch is the only safe choice. SSOUNDS engineers always specify managed switches for Dante deployments to ensure deterministic performance and easy diagnostics.

Start by disabling EEE on all ports. This is often found under power-saving or port settings. Next, enable IGMP snooping with querier enabled on the VLAN used for Dante. The querier ensures that multicast group membership is maintained.

Configure QoS: set up four queues (or more) and map DSCP values to the highest queue. Dante audio (DSCP 46) should go to queue 3 (strict priority), control (DSCP 34) to queue 2, and best-effort traffic to queue 0. Ensure that the switch trusts incoming DSCP markings.

VLANs are recommended to separate Dante traffic from other network traffic (e.g., control, video, or general IT). Create a dedicated VLAN for audio, assign all Dante device ports to it, and configure the switch to route only that VLAN to the Dante subnet.

Finally, disable spanning tree (STP) on Dante ports or use rapid spanning tree (RSTP) with edge ports. STP can cause 30-second delays when a device connects, which is unacceptable for live audio. Alternatively, use portfast or edge-port mode to bypass STP on Dante ports.

For small portable systems (e.g., a single stage box and a console), a compact managed switch like the Netgear GS108T or Cisco SG250-08 is sufficient. Ensure it supports IGMP snooping and QoS.

For medium installations (e.g., a church, corporate AV, or small tour), consider the Ubiquiti USW-24-POE or Netgear M4300 series. These offer PoE, SFP+ uplinks, and full management features at a reasonable cost.

For large-scale touring or fixed installations, enterprise switches from Cisco (Catalyst 9300), Arista (7050X), or Extreme Networks are common. They provide high port density, redundant power, and advanced features like Precision Time Protocol (PTP) for video sync.

SSOUNDS recommends always testing a switch with your specific Dante devices before deployment. Use Dante Controller's latency and clock health tools to verify performance. A properly configured switch will show sub-millisecond latency and zero errors.
