28-Port Managed Business Gigabit Switch LINKSYS LGS528
ADVANCED NETWORK MANAGEMENT CAPABILITIES
Advanced features include Layer 2 Switching and Layer 3 Static Routing between different VLAN communications without any performance degradation for a more efficient network. Linksys 500 Series Switches manage internal routing with your router and dedicate fixed paths to external traffic and security.
ADVANCED TRAFFIC-HANDLING INTELLIGENCE
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
Extensive Access Control Lists (ACLs) control and block portions of the network from unauthorized users and external network attacks, while DHCP Snooping, IP and MAC-Port Binding functions help ensure network integrity. IEEE 802.1X Port Security strictly limits access to specific segments of your network, and Port Authentication and MAC-based Port Security require clients to authenticate themselves before any data passes.
FIBER-OPTIC NETWORK EXPANSION SUPPORT
Additional Gigabit SFP+ Fiber-Optic port expansions provide a powerful combination of business scalability for any server farm and data center environment, and enhance high bandwidth demands while providing redundancy for fast and easy network growth. Mini Gigabit Interface Converter (mini-GIBC) expansion ports offer the 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.
