FEATURES

QUALITY OF SERVICE (QOS) TRAFFIC PRIORITIZATION
Equipped with multiple QoS features, this switch intelligently prioritizes network traffic—ideal for real-time voice and video applications as well as high-bandwidth graphic or video uploads and downloads.

NETWORK EXPANSION FEATURES
Easily build and expand your network with features like Spanning Tree Protocol (STP) and Storm Control. These technologies prevent accidental or planned cable loops, ensuring reliable connectivity and smooth network scalability.

ADVANCED NETWORK SECURITY
Keep your network protected with advanced security features. Port authentication and MAC-based port security ensure that only authorized clients have access to data. Additional safeguards like DHCP snooping and IP-MAC binding enhance network integrity and help prevent malicious attacks.
