Resilient 10Gbps and Layer 3 Routing Solution for Enterprise Networking  PLANET SGS-6310 series is a brand-new Layer 3 Stackable Managed Gigabit Switch with 10Gbps uplink capability for various kinds of network applications and flexible deployment. The SGS-6310-16S8C4XR features 24 100/1000BASE-X SFP ports and 8 10/100/1000BASE-T RJ45 copper ports, shared with Ports 1 to 8, and 4 1G/10GBASE-X SFP+ ports with 128Gbps switch fabric delivered in a 1U rugged case design.   The SGS-6310 series provides high-density performance, Layer 3 IPv4/IPv6 static routing, RIP and OSPF dynamic routing capability, ERPS ring, abundant L2/L4 switching engine, and virtual switch stacking technology to fulfill the need of heavy transmission of all applications. It gives the enterprises, service providers and campuses flexible control over port density, uplinks and switch stack performance at an affordable price.     High Performance 10Gbps Ethernet Capacity The four SFP+ ports built in the SGS-6310 series boasts a high-performance switch architecture that is capable of providing non-blocking switch fabric and wire-speed throughput as high as up to 80Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands. Each of the SFP+ ports supports Dual-Speed, 10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently.   Centralized Hardware Stacking Management Two of the 10G SFP+ ports can be configured to connect several SGS-6310 series for building a virtually logical facility. The stackable SGS-6310 series, suitable for enterprises, service providers and telecoms, provides high port density, large uplink bandwidth and high switch stack performance, thus giving great flexibility for different application requirements. The SGS-6310 series can connect as a ring for redundancy and ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.     Redundant Ring, Fast Recovery for Critical Network Applications The SGS-6310 series 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 and Spanning Tree Protocol (802.1s MSTP) into customer’s network to enhance system reliability and uptime in harsh environments. In a certain simple ring network, the recovery time could be less than 10ms to quickly bring the network back to normal operation.     Layer 3 Routing Support The SGS-6310 series enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing manually, the RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) settings automatically.  The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination.  The OSPF is an interior dynamic routing protocol for autonomous system based on link state. The protocol creates a database for link state by exchanging link states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.   Strong Multicast The SGS-6310 series supports abundant multicast features. In Layer 2, it features IPv4 IGMPv1/v2/v3 snooping and IPv6 MLD v1 snooping. With Multicast VLAN Register (MVR), multicast receiver/sender control and illegal multicast source detect functions which make the SGS-6310 series great for any robust networking.   Full IPv6 Support  The SGS-6310 series supports IPv4-to-IPv6 technologies including IPv4 manual/automatic tunnel, IPv6-to-IPv4 tunnel, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnel. It comprehensively supports IPv6 Neighbor Discovery, DHCPv6, Path MTU Discovery, IPv6-based Telnet, SSH and ACL, meeting the need of IPv6 network device management and service control.    Robust Layer 2 Features The SGS-6310 series can be programmed for basic switch management functions such as port speed configuration, port aggregation, VLAN, Multiple Spanning Tree Protocol, bandwidth control and IGMP snooping. This switch provides 802.1Q tagged VLAN, Q-in-Q, voice VLAN and GVRP Protocol functions. By supporting port link aggregation, the SGS-6310 series allows the operation of a high-speed trunk combined with multiple ports.  It enables up to 64 groups for trunking with a maximum of 8 ports for each group.      Excellent Layer 2 to Layer 4 Traffic Control The SGS-6310 series is loaded with powerful traffic management and WRR features to enhance services offered by enterprises. The WRR functionalities include wire-speed Layer 4 traffic classifiers and bandwidth limitation which are particularly useful for multi-tenant unit, multi-business unit, Telco, or network service applications. It also empowers the enterprises to take full advantage of the limited network resources and guarantees the best in VoIP and video conferencing transmission.    Powerful Network Security The SGS-6310 series offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It 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. Its protection mechanism also comprises 802.1x Port-based and MAC-based user and device authentications, which can be deployed with RADIUS, to ensure the port level security and block illegal users.   Advanced IP Network Protection The SGS-6310 series also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.   Efficient and Secure Management For efficient management, the SGS-6310 series is equipped with console, Web and SNMP management interfaces. With the built-in Web-based management interface, the SGS-6310 series offers an easy-to-use, platform-independent management and configuration facility.  For text-based management, it can be accessed via Telnet and the console port. For reducing product learning time, the SGS-6310 series offers Cisco-like command and customer doesn’t need to learn new command from these switches For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management. Moreover, the SGS-6310 series offers secure remote management by supporting SSHv1/v2 and TLSv1.2 connection which encrypts the packet content at each session.     AC Redundant Power to Ensure Continuous Operation The SGS-6310-16S8C4XR is equipped with 100~240V AC power supply unit for redundant power supply. A redundant power system is also provided to enhance the reliability with power supply unit. The redundant power system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity.    Intelligent SFP Diagnosis Mechanism The SGS-6310 series supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
