It includes a range of cybersecurity features such as DHCP Snooping, IP Source Guard, dynamic ARP Inspection Protection, 802.1x port-based network access control, RADIUS and TACACS+ user accounts management, SNMPv3 authentication, and so on to complement it as an all-security solution.     Redundant Ring, Fast Recovery for Critical Network Applications The GS-4210-24T4S(R) supports redundant ring technology and features strong, rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) technology, Spanning Tree Protocol (802.1s MSTP) into customer’s network to enhance system reliability and uptime in various environments.     Redundant AC/DC Power Supply to Ensure Continuous Operation The GS-4210-24T4SR is particularly equipped with one 100~240V AC power supply unit and one 36~72V DC power supply unit to provide an enhanced reliable and scalable redundant power supply, the continuous power system is specifically designed to fulfill the demands of high-tech facilities requiring the highest power integrity. With the 36~72V DC power supply, the GS-4210-24T4SR is able to act as a telecom-level device that can be located in the electronic room.   IPv6/IPv4 Dual Stack Management Supporting both IPv6 and IPv4 protocols, the GS-4210-24T4S and GS-4210-24T4SR help the SMBs to step in the IPv6 era with the lowest investment as their network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.      Robust Layer 2 Features The GS-4210-24T4S and GS-4210-24T4SR can be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree protocol (MSTP), loop and BPDU guard, IGMP snooping, and MLD snooping. Via the link aggregation, the GS-4210-24T4S and GS-4210-24T4SR allow the operation of a high-speed trunk to combine with multiple ports, and supports fail-over as well.  Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol included to help discover basic information about neighboring devices on the local broadcast domain.       Efficient Traffic Control The GS-4210-24T4S and GS-4210-24T4SR are loaded with robust QoS features and powerful traffic management to enhance services to business-class data, voice, and video solutions. The functionality includes broadcast / multicast storm control, per port bandwidth control, IP DSCP QoS priority and remarking. They guarantee the best performance for VoIP and video stream transmission, and empowers the enterprises to take full advantage of the limited network resources.   Powerful Security PLANET GS-4210-24T4S and GS-4210-24T4SR offer comprehensive IPv4/IPv6 Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. They can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Their protection mechanism also comprises 802.1X port-based user and device authentication, which can be deployed with RADIUS and TACACS+ to ensure the port level security and block illegal users. With the protected port function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, Port security function allows to limit the number of network devices on a given port.    Friendly and Secure Management  For efficient management, the GS-4210-24T4S and GS-4210-24T4SR are equipped with web, Telnet and SNMP management interfaces.  With the built-in Web-based management interface, the GS-4210-24T4S and GS-4210-24T4SR offer an easy-to-use, platform-independent management and configuration facility. For text-based management, the switches can be accessed via Telnet and the console port. By supporting the standard SNMP, the switches can be managed via any standard management software    Moreover, the GS-4210-24T4S and GS-4210-24T4SR offers secure remote management by supporting SSHv2, TLSv1.2 and SNMP v3 connections which encrypt the packet content at each session.       Flexibility and Long-distance Extension Solution The GS-4210-24T4S and GS-4210-24T4SR provide 4 extra Gigabit SFP interfaces supporting 100BASE-FX/1000BASE-SX/LX SFP (small form-factor pluggable) fiber transceiver to uplink to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and up to above 10/20/40/60/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.   Fanless Design Adopting the latest chip process and green technology, the GS-4210-24T4S and GS-4210-24T4SR successfully reduce substantial power consumption with the fanless and noiseless design collocating with the effective cooler. Therefore, the GS-4210-24T4S and GS-4210-24T4SR are able to operate stably and quietly in any environment without affecting their performance.
