The Best Network Switches for Dante and AoIP

Dante and AoIP systems rely on standard IP networking, but they impose strict requirements on switch performance. The most critical feature is a non-blocking backplane — the switch must be able to handle full wire-speed traffic on all ports simultaneously without dropping packets. For a 48-port gigabit switch, this means a switching capacity of at least 96 Gbps (full-duplex). Any switch that claims to be 'managed' and 'gigabit' should be verified for non-blocking architecture.

Quality of Service (QoS) is essential to prioritize audio packets over other traffic. Dante uses DiffServ (DSCP) to mark audio packets with a specific value (CS6, or 48 decimal). The switch must be able to trust these markings and map them to strict priority queues. Without proper QoS, a burst of file transfers or video streams can cause audio dropouts.

IGMP snooping is mandatory for multicast audio streams. Dante uses multicast to send audio to multiple receivers efficiently. IGMP snooping allows the switch to listen to IGMP membership reports and forward multicast traffic only to ports that have requested it. Without IGMP snooping, multicast traffic is flooded to all ports, wasting bandwidth and potentially causing packet loss.

Energy Efficient Ethernet (EEE, also known as 802.3az) must be disabled on all ports used for Dante. EEE powers down links during idle periods to save energy, but the wake-up time introduces latency and jitter that can corrupt audio. Most managed switches allow EEE to be turned off globally or per port. Unmanaged switches often have EEE enabled and cannot be disabled, making them unsuitable for professional AoIP.

Managed switches are strongly recommended over unmanaged. They allow configuration of VLANs, QoS, IGMP snooping, port mirroring, and SNMP monitoring. For large Dante networks, VLANs can separate audio traffic from control and data traffic, improving security and performance. Managed switches also provide diagnostics and troubleshooting tools.

Gigabit Ethernet is the minimum for Dante. While 100 Mbps can theoretically carry a few channels, modern Dante networks often run at 96 kHz with many channels, and gigabit provides headroom for redundancy (Dante Redundant) and future expansion. PoE (Power over Ethernet) is useful for powering Dante-enabled microphones and speakers, but ensure the switch provides sufficient PoE budget and that PoE does not interfere with audio performance.

For large venues or distributed systems, fibre uplinks between switches are essential. Fibre supports longer distances (up to 10 km or more) and is immune to electromagnetic interference. SFP ports on switches allow you to choose the appropriate fibre transceiver (multimode for short runs, single-mode for long runs). When using fibre, ensure the switch supports the same QoS and IGMP settings on SFP ports as on copper ports.

Network topology matters. For Dante, a star topology (each device connects to a central switch) is simplest and most reliable. Daisy-chaining switches is possible but increases latency and risk of single points of failure. For redundancy, Dante's primary and secondary networks should be completely separate — two independent switches, two cables, and two NICs on each Dante device. Never connect the primary and secondary networks to the same switch.

Start by disabling EEE on all ports. Then configure QoS: set the switch to trust DSCP markings and map DSCP 48 (CS6) to the highest priority queue. For switches that use 8 queues, map CS6 to queue 7; for 4 queues, map to queue 3. Ensure that the queue is strict priority (not weighted fair queuing) so that audio packets are always served first.

Enable IGMP snooping globally and on the VLANs used for Dante. Set the IGMP query interval to 125 seconds (default) and the robustness variable to 2. Some switches allow IGMP fast leave, which can be enabled to reduce latency when devices disconnect. Disable IGMP querier if another device on the network is acting as querier (e.g., a router); otherwise, enable it on the switch.

Configure VLANs: place all Dante devices on a dedicated VLAN (e.g., VLAN 10) and keep control traffic (e.g., Dante Controller) on the same VLAN. If you have other network services, put them on separate VLANs and use a router to route between them if needed. Ensure that the switch ports connecting to Dante devices are set to access mode (or trunk with the correct VLAN).

For small systems (up to 32 channels), a managed 8-port gigabit switch with PoE is sufficient. Look for models from reputable manufacturers that explicitly support Dante (e.g., Cisco SG series, Netgear M4100, or Luminex). For medium systems (up to 128 channels), a 24-port managed switch with SFP uplinks and PoE+ is recommended. For large systems (hundreds of channels), use a 48-port switch with 10GbE uplinks for future-proofing.

Consider environmental factors: for touring or outdoor use, ruggedized switches with wide temperature ranges and fanless designs are preferable. For fixed installations, enterprise-grade switches with redundant power supplies offer reliability. Always verify that the switch firmware is up to date and that the manufacturer provides support for Dante-specific configurations.

SSOUNDS engineers have deployed Dante networks in hundreds of venues worldwide, from small clubs to large festivals. Our experience shows that a properly configured managed switch — regardless of brand — will outperform any unmanaged switch. We recommend investing in quality switches from the start to avoid costly downtime.
