What is the NETGEAR M4350-16C?

The M4350-16C is a 16-port, 100 Gigabit QSFP28 fully managed switch designed for high-capacity AV and IT networks. It supports Layer 2 and Layer 3 operation, non-stop forwarding virtual chassis stacking, AV-focused configuration profiles and Grandmaster or Boundary Clock operation for supported SMPTE ST 2110, AES67 and ST 2059-2 applications.

16 × QSFP28 Physical ports supporting 40G and 100G operation

3.2Tbps Line-rate routing and switching capacity

2380.8Mpps Listed throughput using 64-byte packets

1U Rackmount Full-width 440 × 43.2 × 400mm chassis

High-Capacity 100G Switching

Sixteen QSFP28 interfaces and a 3.2Tbps switching fabric for high-bandwidth network aggregation and core connectivity.

The M4350-16C provides 16 QSFP28 ports supporting 40 Gigabit and 100 Gigabit connections. The supplied datasheet lists line-rate performance of 2380.8Mpps, a 256Mb packet buffer, 4GB DDR4 memory and latency below 1.22 microseconds at 100G.

Jumbo frames of up to 12KB are supported, together with a 16K MAC address table, 4K ARP entries, 512 IPv6 NDP entries and up to 4K VLANs.

Management and AV Configuration

Dedicated AV tools are provided alongside standard IT management interfaces.

Dedicated AV User Interface

A simplified AV-focused interface allows configuration profiles to be assigned to individual ports using colour-based profile identification.

NETGEAR Engage Controller

The Engage Controller provides centralised configuration for supported M4250, M4300, M4350 and M4500 switches across an AV network.

NETGEAR IGMP Plus

NETGEAR IGMP Plus provides automated multicast functionality intended to simplify most AV-over-IP multicast installations.

Auto-Trunk and Auto-LAG

Auto-Trunk and Auto-LAG can automatically configure links between compatible M4350 and M4250 switches.

Industry-Standard Management

Management options include an IT web GUI, command-line interface, HTTPS, SSH, Telnet, SNMP, MIBs, RSPAN, RADIUS users and TACACS.

Out-of-Band Access

The switch includes a rear 1GbE out-of-band management port, front USB Type-C console connection and two rear USB Type-A storage ports.

Virtual Chassis Stacking and High Availability

Non-stop forwarding supports resilient stacked network configurations.

Stacking Features

Virtual chassis stacking with non-stop forwarding and hitless management failover.
Any suitable 100G port can be configured for stack operation.
A port configured in Stack mode operates at its highest supported stacking speed.
Up to two M4350 switches are supported in a core stack configuration.
Up to eight M4350 switches may be stacked at the IT access layer.

Important Stacking Limitation

Stacking, AVB and PTP Transparent Clock operation are mutually exclusive. A stack cannot simultaneously run AVB or PTP Transparent Clock, Boundary Clock or Grandmaster Clock modes.

For AV applications, the supplied datasheet specifies two-switch stacks because multicast traffic is replicated between the two switches.

Layer 3 Routing and Network Control

The complete Layer 2 and Layer 3 feature set is supplied without a separate software licence.

Routing

IPv4 and IPv6 static routing
Policy-based routing
RIP and VRRP
OSPF
PIM-SM, PIM-DM and SSM
Multicast static routes
DHCP server and DHCP relay

Switching and Security

Static and dynamic VLANs
Voice, MAC and private VLANs
Static LAG and dynamic LACP
STP, MSTP, RSTP and per-VLAN spanning tree
DHCP snooping and Dynamic ARP Inspection
IP Source Guard
802.1X, MAB and Captive Portal authentication

SMPTE ST 2110 and Precision Timing

Timing modes and profiles are supplied for supported professional AV environments.

The M4350-16C supports SMPTE ST 2110 profiles, Grandmaster Clock and Boundary Clock modes. Supplied PTP profiles include SMPTE ST 2059-2 for video and audio, AES67 for audio and AES-R16-2016 interoperability.

The switch supports single-step and two-step PTP operation between the Grandmaster and connected AV endpoints.

Power, Cooling and Acoustics

An internal power supply is included, with a modular PSU bay available for redundant power.

420W Internal Power Supply

The switch includes one fixed 420W internal power supply with a C14 inlet and power switch.

Modular PSU Bay

One modular PSU slot supports a compatible additional power supply for 1+1 power redundancy.

Quiet or Cool Operation

Intelligent fans can be configured in Quiet Mode to reduce noise or Cool Mode to reduce operating heat.
