18-port, Gigabit switch delivers high-quality performance and reliability for business-class management, security and speed. 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. 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. Spanning Tree Protocol (STP) and Storm Control features let you confidently build a mesh of switches and quickly expand your network to support your growing workforce.
