Quality of Service (QoS) Traffic Prioritization

Numerous QoS features prioritize traffic, ideal for real-time voice and video applications & high bandwidth graphic or video uploads and downloads.

Integrated Power over Ethernet Plus (PoE+)

Makes installation simple and inexpensive by eliminating the need for additional power cables and nearby power outlets. Backwards compatible with 802.3af (PoE) standard.

Network Expansion Features

Build a mesh of switches easily with features like Spanning Tree Protocol (STP) and Storm Control. They help control planned or inadvertent cable loops so you can expand your network with confidence.

Advanced Network Security

Ensure data passes to authorized clients only with Port authentication and MAC-based port security. Advanced DHCP snooping and IP-MAC binding functions assure network integrity and help prevent attacks.

Designed for business-class management, security, speed, and quality of service, Linksys Smart PoE+ Gigabit Switches provide a network your business can grow on.

Quality of Service (QoS)

Numerous QoS features ensure that traffic is prioritized properly to deliver the best possible user experience for real-time applications like voice and video along with bandwidth-intensive graphic/video file uploads and downloads. IGMP snooping limits IP multicast traffic to the ports that requested it, enabling the rest of the network to operate at peak efficiency.

Power over Ethernet Plus (PoE+)

Linksys smart switches support the latest 802.3at (PoE+) standards and provide up to double the power budget per Gigabit Ethernet port while offering 802.3af (PoE) backward-compatibility. Power over Ethernet reduces electrical wiring costs, simplifies installation, and supports network devices such as IP cameras and wireless access points in optimal indoor and outdoor locations.

Network Security

Unauthorized access to the network and mission-critical data is a constant concern. Linksys smart switches help secure networks through port authentication and MAC-based port security, requiring clients to authenticate themselves before any data is passed. Advanced DHCP snooping and IP-MAC binding functions ensure network integrity and help prevent network attacks.

Network Expansion

Linksys smart switches include features for quickly expanding and growing your network. Multiple high-bandwidth trunks between switches enhance availability and redundancy. Spanning Tree Protocol (STP) and Storm Control features help control planned or inadvertent cable loops, so you can confidently build a mesh of switches and quickly expand your network to support your growing workforce.
