Advanced network management capabilities Control and manage your business network with advanced features including layer 2 switching and layer 3 static routing between different VLAN communications without any performance degradation. As a result your network can run more efficiently,as Linksys 500 Series switches will manage internal routing with your router and dedicate fixed paths with external traffic and security. Advanced traffic-handling intelligence Deliver superior communication via video,voice and data applications over your business network with advanced QoS features. Layer 2 MAC and layer 3 IP flow-based policies and rate limiting control prioritize traffic,offering an ideal solution to manage and control real-time,high bandwidth,voice and video traffic without slowing down your other business applications. Advanced network security features Safeguard your business network with extensive Access Control Lists (ACLs) to control and block portions of the network from unauthorized users and external network attacks. Detect and prevent network attacks with DHCP snooping,IP and MAC-port binding functions that ensure network integrity. IEEE 802.1X Port Security strictly limits access to specific segments of your network,while port authentication and MAC-based port security requires clients to authenticate themselves before any data is allowed to pass. Fiber-optic network expansion support With an additional Gigabit SFP+ fiber-optic port expansions,Linksys 500 Series Switches provide a powerful combination of business scalability for any server farm and data center environment,and enhances high bandwidth demands while providing redundancy for fast and easy network growth. Mini Gigabit interface converter (mini-GIBC) expansion ports offer you an option to add fiber-optic or Gigabit Ethernet uplink connectivity to these managed switches. Optimal energy-efficient ethernet support Reduce energy consumptions by monitoring the amount of traffic and states of any inactive ports without compromising performance. Linksys 500 Series switches are specifically designed to optimize power and efficiency and support the energy-efficient Ethernet (IEEE 802.3az) standards.
