The Best Network Switches for Dante and AoIP

A Dante-compatible switch must meet specific hardware and software requirements to handle uncompressed, low-latency audio streams without dropouts or jitter. The most critical feature is a non-blocking backplane: every port must be able to communicate at full wire speed simultaneously. For example, a 48-port gigabit switch should have a switching capacity of at least 96 Gbps (full-duplex). Without this, audio packets can be dropped during peak traffic.

Quality of Service (QoS) or DiffServ marking is mandatory for Dante. Dante uses DSCP (Differentiated Services Code Point) values to prioritise audio traffic (typically EF for time-critical audio and CS3 for control). The switch must be configured to trust these markings and queue audio packets ahead of best-effort data. Managed switches allow fine-grained QoS policies, while unmanaged switches often ignore DSCP, making them unsuitable for larger Dante networks.

IGMP snooping is another essential feature. Dante uses multicast to send audio from one source to multiple receivers efficiently. Without IGMP snooping, multicast traffic is flooded to all ports, wasting bandwidth and potentially causing congestion. IGMP snooping lets the switch learn which ports want which multicast streams and forwards only to those ports. All managed switches support this, but it must be enabled and configured correctly.

Gigabit Ethernet (1000BASE-T) is the minimum for Dante. While 100 Mbps can handle a few channels, modern systems with 64+ channels or high sample rates quickly exceed its capacity. Gigabit provides headroom for multiple streams, redundant networks, and future expansion. For large installations, 10 GbE uplinks between switches or to servers are recommended.

Energy-Efficient Ethernet (EEE, 802.3az) must be disabled on all ports carrying Dante traffic. EEE powers down links during idle periods to save energy, but the wake-up latency (tens of microseconds) can cause clock drift and audio dropouts. Most managed switches allow EEE to be turned off globally or per-port. Unmanaged switches often have EEE enabled by default, which is a common source of intermittent problems.

For any Dante network with more than a few devices, a managed switch is strongly recommended. Managed switches give you control over QoS, IGMP snooping, VLANs, and port-level settings, all of which are crucial for reliable AoIP. They also provide diagnostics like port statistics and mirroring for troubleshooting. Unmanaged switches are plug-and-play but lack these features, making them suitable only for very small, static networks (e.g., a single room with a few channels).

Even for small setups, a low-cost managed switch from a reputable brand (e.g., Cisco, Netgear, TP-Link, Ubiquiti) is a better investment. Many entry-level managed switches now cost under $100 and offer web-based configuration. SSOUNDS engineers always recommend managed switches for Dante because they allow precise tuning of the network to match the audio system's demands.

PoE is optional but very useful for powering Dante-enabled microphones, wall plates, or small stage boxes. PoE+ (802.3at) provides up to 30W per port, enough for most devices. When selecting a PoE switch, ensure the total power budget meets your device requirements. Some switches also support PoE passthrough for daisy-chaining.

Fibre uplinks are important for long cable runs (over 100 m) or in electrically noisy environments. Fibre is immune to ground loops and EMI, making it ideal for connecting stages to FOH or linking multiple buildings. Many managed gigabit switches have SFP (Small Form-factor Pluggable) slots for fibre transceivers. For Dante, single-mode fibre with LC connectors is common for distances up to 10 km.

Start by disabling EEE on all ports. Then configure QoS: set the switch to trust DSCP and map EF (DSCP 46) to the highest priority queue, CS3 (DSCP 24) to a medium queue, and all other traffic to best-effort. Enable IGMP snooping and set the IGMP query interval to 125 seconds (default on most switches). If using VLANs, keep Dante traffic on a dedicated VLAN to isolate it from data traffic.

For redundancy, Dante supports two methods: daisy-chaining (using primary and secondary ports) or a redundant network with two separate switches. In the latter, configure identical settings on both switches and connect each Dante device's primary port to switch A and secondary to switch B. This requires a managed switch that supports RSTP (Rapid Spanning Tree Protocol) to prevent loops, but RSTP must be configured carefully to avoid blocking audio paths.

Finally, use Dante Controller's network diagnostics to verify the switch configuration. Check for errors, jitter, and clock sync. If you see 'Flapping' or 'Late' packets, revisit your QoS and IGMP settings. SSOUNDS provides detailed network guidelines with every system, and our support team can assist with switch recommendations and configuration templates.

While any switch that meets the criteria above can work, some brands are more trusted in the pro-audio community. Cisco Catalyst and SG series are widely used for their robust QoS and reliability. Netgear M4250 and M4300 series are purpose-built for AV-over-IP, with pre-configured Dante profiles. TP-Link JetStream and Ubiquiti EdgeSwitch offer good performance at lower price points. For large-scale installations, Arista and Extreme Networks provide data-center-grade switches with high port density and low latency.

SSOUNDS systems have been deployed with all these brands. The key is not the brand but the configuration. A cheap switch configured correctly will outperform an expensive switch with default settings. Always test your network with Dante Controller before a show, and keep a spare switch on hand for critical events.
