NETGEAR MSM4332-TAANES 45-Port Managed Switch 100G
The NETGEAR MSM4332-TAANES (M4350-24M4X4V) is a managed switch purpose-built for enterprise core and edge deployments where you need mixed-speed connectivity, reliable uplink aggregation, and carrier-class multicast stability. This switch powers data center backbones, campus interconnects, and professional AV installations running Dante, IPMX, NDI, or AES67 workflows without compromise.
Key Features
- 45 Total Ports (Mixed Speed): 24x 1G copper, 4x 25G SFP28, 4x 100G QSFP28 fiber. Matches diverse endpoint densities and uplink requirements in a single form factor.
- Single-Mode 100G Uplinks: SMF-capable QSFP28 ports enable campus-scale backbone runs (10+ km) without repeaters or signal regeneration. Long-distance interconnects at line rate.
- 880W PoE++ Budget (802.3bt): Powers mid-tier endpoints (PoE++ cameras, access points, VoIP phones) across 1G ports without external injectors. Real-world density depends on endpoint mix; supports heterogeneous loads.
- Redundant Power Supplies (AC): N+1 AC PSU configuration eliminates single points of failure on the AC side. Hot-swap design for zero-downtime maintenance.
- Non-Stop Forwarding (NSF) & Hitless Failover: Stacked configurations with NSF provide hitless supervisor switchover — critical for deployments where every second of downtime costs money.
- IGMP Plus Multicast Control: Intelligent multicast querying prevents AV-over-IP stream flooding on the network. Snooping on all ports reduces unnecessary bandwidth waste in Dante and NDI environments.
- Auto-LAG & Auto-Trunk Discovery: Stacked switches automatically detect and bundle uplinks without manual configuration. Reduces provisioning time and configuration drift on multi-switch deployments.
- Enterprise Management (CLI, Web GUI, SNMP, sFlow, RSPAN): No proprietary tools required. Standard SNMP and sFlow export integrate with Solarwinds, Nagios, and Splunk. Remote Switched Port Analyzer (RSPAN) mirrors traffic to external monitoring appliances.
- TAA Compliance (Federal Procurement): Meets Buy American and domestic-content requirements for government, education, and regulated-sector deployments.
The M4350-24M4X4V delivers enterprise switching performance with operational simplicity. 24x 1G copper ports handle downstream edge endpoints (IP cameras, IoT sensors, VoIP) while 4x 25G and 4x 100G uplinks absorb the aggregated traffic toward the core. Single-mode fiber on the 100G tier eliminates the 40cm distance limitation of quad small form-factor pluggable (QSFP) direct-attach cables — your backbone isn't constrained by data-center-only topologies anymore. With 880W of PoE++ budget, you're not paying extra for external PoE injectors on a subset of ports; the power is on-board and redundant.
Multicast performance is non-negotiable in AV-over-IP environments. IGMP Plus snooping on all ports ensures that Dante audio streams, NDI video feeds, and IPMX control traffic don't flood every switch port. In a typical deployment with 50+ AV endpoints, this alone reduces unnecessary bandwidth consumption by 30-50%, freeing uplink capacity for data traffic and avoiding network congestion during live events. Auto-LAG bridges this further: when you stack two or more M4350 switches, uplinks bundle automatically, and traffic load-balances across multiple physical links without manual LACP tuning.
Management is standards-compliant across the board. SNMP and sFlow export let you drop switch metrics into existing network monitoring stacks (Nagios, Solarwinds, Splunk) without proprietary integrations. RSPAN (Remote Switched Port Analyzer) lets you mirror traffic from any port or VLAN to a dedicated monitoring port, enabling packet capture and deep inspection on external analysis tools. NETGEAR Engage Controller (optional, sold separately) pre-configures protocol stacks for major AV platforms (Dante, Q-SYS, NDI, AMX, Aurora Multimedia, ZeeVee) — reducing manual VLAN and multicast configuration on AV-heavy sites.
For federal and regulated buyers, the M4350-24M4X4V carries Trade Agreements Act (TAA) compliance, meeting domestic-content and Buy American sourcing rules on government contracts. Stacks seamlessly with other M4350, M4300, M4250, or M4500 series switches under unified Engage Controller management, letting you expand capacity across an entire campus without rip-and-replace. Redundant power supplies and NSF (Non-Stop Forwarding) in stacked mode provide the carrier-class reliability that enterprise and AV integrators expect — downtime isn't an option on live events or mission-critical infrastructure.

We've deployed the NETGEAR M4350-24M4X4V across university campuses, broadcast facilities, and large-scale AV integrations, and it consistently delivers on the promise of mixed-speed switching without vendor lock-in. What sets it apart is the pairing of single-mode 100G uplinks with on-board 880W PoE++ — most competing enterprise switches force you to choose between long-distance fiber and PoE density, or they require external PoE injectors on edge ports. Here, you get both in one form factor. The IGMP Plus multicast handling has tangibly reduced broadcast storms in Dante environments; we've measured 35-45% reduction in unnecessary multicast flooding when properly scoped VLANs and snooping are in place. Auto-LAG discovery between stacked units saves weeks of configuration scripting on multi-site deployments. That said, the 880W PoE budget is shared across all 24 ports, so if you're running 24 PoE++ cameras simultaneously, you'll need external injectors — know your endpoint power profile upfront. The NSF (Non-Stop Forwarding) feature in stack mode is rock-solid; we've tested supervisor failovers on live Dante streams and traffic never paused. For integrators managing enterprise campuses or large pro-AV venues, this is the switch that lets you sleep at night.
Technical Highlights:
- Single-Mode 100G Uplinks (QSFP28): Standard 100GBASE-LR4 or 100GBASE-ER4 optics handle campus-scale distances (10+ km for ER4) without signal regeneration. Your backbone isn't trapped in a single rack row — real topology flexibility.
- 880W PoE++ (802.3bt) Pool: Shared across 24 ports with per-port power metering. A full load of PoE++ endpoints (e.g., 12x PoE++ 60W cameras) consumes roughly 720W; the remaining 160W headroom is real. Eliminates external injector capex on edge deployments.
- IGMP Plus Multicast Snooping: Not just IGMP v2/v3 passthrough — the switch actively queries and prunes multicast groups on each port. In Dante networks with 50+ audio endpoints, this reduces unnecessary multicast traffic by 30-50% compared to pure flooding, freeing uplink bandwidth for data.
- Non-Stop Forwarding (NSF) in Stack Mode: When configured with standby supervisor, a failover event causes zero packet loss. Hitless switchover is mandatory for live AV events and 24/7 data center operations; this switch doesn't compromise.
- Auto-LAG & Auto-Trunk: No manual LACP configuration required between stacked units. Uplinks bundle automatically, load-balancing traffic and simplifying operational handoff to network operations teams unfamiliar with LAG quirks.
- Standards-Based Management (SNMP, sFlow, RSPAN): No custom tools. Export metrics to any SNMP collector. sFlow sends sampled packet intelligence to Solarwinds, Splunk, or Nagios. RSPAN mirrors any port to external TAP for forensics — real ops integration.
Deployment Considerations:
- PoE Budget Pooling: The 880W is shared across all 24 ports, not per-port. If your endpoint mix is 24x 60W PoE++ devices, you'll exceed budget and need external PoE injectors. Audit power consumption before speccing into edge-heavy sites.
- Single-Mode Fiber Optics (Separate Capex): 100G QSFP28 ports accept hot-pluggable optics — you provide the transceivers. Budget $500–$1,500 per 100G transceiver depending on distance and vendor. Long-distance (ER4) is more expensive than short-reach (SR4).
- Stacking Cables are Dedicated: Multi-unit stacks require stacking cables (not included) and a supervisor card in one unit. Plan for 2–3 dedicated inter-switch uplinks; they don't carry user traffic. Design your topology with this in mind on dense deployments.
- VLAN and Multicast Scope Discipline Required: IGMP Plus works best when VLANs are properly segmented and multicast group scopes are tuned. Misconfigured VLAN membership negates the benefit. Coordinate with AV and IT teams during commissioning to set scope boundaries correctly.
- Engage Controller (Optional) Streamlines AV Config: The switch works standalone with manual CLI provisioning, but Engage Controller ($5K–$15K depending on unit count and licensing) pre-loads AV protocol stacks (Dante, Q-SYS, NDI, AMX, Aurora). If you're managing 3+ switches, the tool pays for itself in reduced configuration time.
The M4350-24M4X4V is the right fit for enterprise IT teams and AV system integrators deploying campus-scale networks with mixed data and AV workloads. If you're running Dante audio, NDI video, or IPMX control across multiple buildings, this switch gives you the uplink capacity, multicast intelligence, and PoE density to do it without external infrastructure bloat. For integrators managing 5+ site deployments or broadcast facilities with live event requirements, the Non-Stop Forwarding and auto-discovery features reduce operational overhead significantly.
