Supply managed switches, 8/16/24 Mbps Switch GL fool! 16 Gigabit Switch GL-2100SM series switches is a new generation of chips crown associated company developed high-performance workgroup, enterprise-class Gigabit switches. The switches have a 12-52 Gigabit ports, support for a variety of connection 10/100 / 1000M can flexibly configure the network as needed. GL-2100SM series switches can be connected to all Ethernet, Fast Ethernet devices, good compatibility with existing equipment. The switches are available in a workgroup or enterprise among gigabit, high-bandwidth, high-performance connectivity, while enhancing the capacity of the server cluster, allowing users to more quickly access the network resources. This switch can alleviate network bottlenecks because of insufficient network bandwidth and user caused by rapid growth and low investment, simple management. Product features: superior performance n maximum backplane bandwidth 104Gbps, non-blocking design, support wire-speed forwarding n gigabit fiber supports a maximum distance of 80 km transmission, can be directly connected to the metro backbone network of high security and reliability provided 802.1 n x other means of user authentication n powerful ACL, hardware support L2-L7 data filtering layer n -MAC-IP multi-port n support specific binding ARP intrusion detection function, which can effectively prevent ARP spoofing attacks by hackers flexible management n function automatically recognizes straight-through cables and crossover cable n using clustering technology to support multiple devices are stacked, using a unified centralized IP address management, address resource savings by controlling the port n, Telnet, Web, SNMP management and other methods Powerful traffic and broadcast management n automatically detect and suppress broadcast storm detection support I高标准 packets, broadcast packets effectively limit the spread of n support full duplex and half-duplex mode flow control n Ethernet interface with a minimum 64K is the rate limiting step n support IP multicast and QoS specifications: 2110SM 2116SM 2124SMD 2124 / 48SFM 2152SM standard configuration 8 Gigabit ports 2 Gigabit optical ports 1 Console port 14 Gigabit ports 2 Optical Multiplexing Gigabit ports 1 Console port 20 Gigabit ports 4 Gigabit ports multiplexed photoelectric a Console port 20/44 Gigabit SFP port 4 Gigabit ports multiplexed photoelectric a Console port 48 Gigabit electrical ports 4 Gigabit SFP optical ports 1 Console port backplane bandwidth of 24Gbps 32Gbps 56Gbps 56Gbps 104Gbps full wire-speed forwarding rate filtering store and forward switching mode forwarding address 8K using half-duplex backpressure flow control, full duplex using IEEE802.3x broadcast suppression broadcast storm control, reaches a critical point stops sending I高标准 multicast control messages automatically monitor QOS support four priority queues for each group of the largest port bundling eight 802.1p, while supporting 8 groups, or dynamic LACP Static stacked cluster aggregation IEEE 802.1D-1998 bridge spanning the connection path of the backup, IEEE 802.1w (RSTP) and IEEE 802.1s (MSTP) VLAN support port-based VLAN, 802.1Q tag VLAN, GVRP dynamic VLAN configuration VLAN number of 4K arbitrary division of QinQ support QoS support Quality of Service (QoS) Head Of Line prevent congestion mechanism best effort service (Best-Effort Service) Differentiated Services (Differentiated Service) Strict Priority Round Robin (Strict Priorty) Weighted Round Robin Priority (Weighted Round Robin) algorithm FCFS (First come first served) TOS relabeled traffic shaping (RTS) network management SNMP, Telnet, RMON, CLI, support a variety of common network management software, network security IEEE 802.1x, port-based access control, RADIUS, TACACS + hardware support dhcp snooping feature hardware support DAI function, static and dynamic arp defense hardware support IP ACL, MAC ACL, Vlan ACL appearance of size 280 * 180 * 44mm 442 * 208 * 44mm 442 * 315 * 44mm 442 * 315 * 44mm 442 * 374 * 44mm Power Supply AC 110-240V adaptive characteristics, 47-63Hz, 1A / 230V power indicator lights, the system indicates the connection / receive instructions, run the 10 / 100M indicate ambient temperature / humidity 0-50 ℃, -40 stored at -70 ℃, 0-90% non-condensing
