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.
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.
