FEATURES

ADVANCED NETWORK MANAGEMENT CAPABILITIES
The Linksys LGS552P switch delivers advanced Layer 2 switching and Layer 3 static routing for seamless VLAN communication without any performance degradation. It efficiently manages internal routing alongside your router and dedicates fixed paths to external traffic and security, ensuring a faster, more reliable network.

INTEGRATED POWER OVER ETHERNET PLUS (POE+)
Simplifies installation by eliminating the need for extra power cables or nearby outlets. Fully backward compatible with the 802.3af (PoE) standard.

ADVANCED TRAFFIC-HANDLING INTELLIGENCE
Layer 2 MAC and Layer 3 IP flow-based policies with rate-limiting control prioritize traffic, making it easy to manage high-bandwidth, real-time voice and video applications without impacting other critical business operations.

ADVANCED NETWORK SECURITY FEATURES
Extensive ACLs block unauthorized users and external attacks. DHCP snooping, IP-MAC-Port binding, and IEEE 802.1X Port Security ensure network integrity. Port authentication and MAC-based port security require clients to verify their identity before transmitting data.
