5-Port 10GbE Lite Managed Switch

QNAP QSW-L3205-1C4T

The QSW-L3205-1C4T combines five full 10GbE network ports with practical Lite Managed features for video editing, backups, surveillance streaming and other high-bandwidth environments. It provides four 10GbE Multi-Gig RJ45 ports and one flexible 10GbE SFP+/RJ45 combo port in a fanless desktop design.

What is the QNAP QSW-L3205-1C4T?

The QSW-L3205-1C4T is a five-port Lite Managed 10GbE switch designed to provide faster network connectivity without the complexity of a full Layer 2 managed switch. It supports LACP, VLAN, QoS, port mirroring, IGMP Snooping, flow control and loop detection through the QNAP Switch System web interface.

5 × 10GbEFour RJ45 ports plus one SFP+/RJ45 combo port

100GbpsSwitching capacity with 50Gbps non-blocking throughput

Up to 20GbpsTotal bandwidth with supported LACP link aggregation

FanlessDesktop operation with IEEE 802.3az Energy Efficient Ethernet

Flexible 10GbE Copper and Fibre Connectivity

Five high-speed ports support versatile network designs and multiple link speeds.

The switch provides four 10GbE RJ45 ports that support 10G, 5G, 2.5G, 1G and 100M network speeds. Its additional combo port can operate as either a 10GbE SFP+ connection or an RJ45 copper connection supporting the same five speeds.

The SFP+ interface is backward compatible with 1GbE SFP modules. The RJ45 ports can be used with Cat 6 or higher cables for the supported Multi-Gig connections described in the supplied product information.

Practical Lite Managed Network Control

Essential traffic, bandwidth and monitoring tools without unnecessary management complexity.

LACP Link Aggregation

Combines network links for greater bandwidth and connection stability, with support for up to 20Gbps of total bandwidth.

VLAN Segmentation

Separates departments, devices or applications to improve resource management, security and network efficiency.

QoS Traffic Prioritisation

QoS, CoS and DSCP scheduling helps priority applications such as VoIP, video streaming and backups receive stable bandwidth.

IGMP Snooping

Manages multicast traffic to reduce unnecessary network load in IPTV, NVR and multi-stream environments.

Port Mirroring

Duplicates selected port traffic for monitoring and troubleshooting to help identify network issues.

Flow and Loop Control

Flow control regulates high-speed traffic, while built-in loop detection blocks affected ports to restore normal operation.

Designed for Smooth High-Bandwidth Workflows

High-speed switching and packet control support demanding network traffic.

The QSW-L3205-1C4T is designed for video editing, data backup and surveillance streaming. Support for IGMP Snooping and 12K jumbo frames helps maintain smooth multimedia playback, multi-stream NVR traffic and NAS performance.

Its 16K MAC address table, 50Gbps total non-blocking throughput and 100Gbps switching capacity support efficient traffic handling across all five ports.

Lite Managed, L2 Managed or Unmanaged?

The supplied comparison positions Lite Managed switching between plug-and-play unmanaged switches and more advanced Layer 2 management.

Management Type	Key Features	Management Advantages	Ideal Use Cases
Lite Managed	LACP / VLAN / QoS / Port Mirroring	Simple yet effective traffic segmentation and rate control	SMBs, retail, basic multi-device segmented surveillance
L2 Managed	ACL / SNMP / RSTP	Fine-grained traffic and security control, full monitoring and troubleshooting	Virtualization, storage networks, enterprise surveillance, campus networks
Unmanaged	EEE / Flow Control / Loop Protection	Plug-and-play deployment with stable, maintenance-free connectivity	Homes, SOHOs, meeting rooms

Simple QSS Management and Firmware Updates

A graphical web interface keeps configuration and maintenance straightforward.

The QNAP Switch System (QSS) provides an intuitive graphical interface for fast, organised network management. QSS and Qfinder Pro can also be used to check and apply firmware updates with a single click.

The switch is made and designed in Taiwan and is presented as a stable and reliable networking solution.
