Võrguseade LevelOne GTL-2872 Fiber Switch

LevelOne KILBY 28-Port L3 Lite Managed Gigabit Fiber Switch GTL-2872The GTL-2872 switch is a Gigabit Ethernet access switch with four 10G uplink ports. The switch is ideal for Internet Service Providers (ISPs) and Multiple System Operators (MSOs) to provide home users with triple-play services with up to Gigabit bandwidth. It is also an ideal Gigabit access switch for SMB, enterprise, and campus networks. The GTL-2872 switch is packed with features that bring high availability, comprehensive security, robust multicast control, and advance QoS to the network edge, while maintaining simple management. The switch also supports the most advance IPv6 management, IPv6 security, and IPv6 multicast control in accordance with the growth of IPv6 deployment. ISPs can expand their services from home to business users by providing a more reliable and resilient network (ITU-T G.8032 ERPS), L2 VPNs, and advanced OAM (Operations, Administration, and Maintenance) functions to ensure service-level agreements.Standards:IEEE 802.3 10-BASE-T, EthernetIEEE 802.3u 100-BASE-TX, Fast EthernetIEEE 802.3ab 1000BASE-T, Gigabit EthernetIEEE 802.3ad Link Aggregation Control ProtocolIEEE 802.3ae changeable (10GBASE-SR/LR/ER)IEEE 802.3z (1000BASE-SX/LX/LHX/ZX) transceivers, and 10G DAC/AOCIEEE 802.3x Flow ControlIEEE 802.3x for full duplex mode , Back-Pressure for half duplex modeIEEE 802.1D Spanning Tree Protocol (STP)IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)IEEE 802.1s Multiple Spanning Tree Protocol (MSTP)Memory: Flash 256MBBuffer Memory: DRAM 512MBPort:20 x 1G SFP port4 x 10/100/1000 (RJ45/SFP) Combo port4 x SFP+ 10 Gigabit Uplink Port1 x RJ45 Console portIndicator: PWR, DIAG, LINKPower Input: 100-240VAC, 50-60HzDC Power Input (48-60VDC)Power Consumption: 21.48WBackplane (Gbps): 128GbpsMAC Address Table: 16KPower Saving: IEEE 802.3az Energy-Ef?cient Ethernet (EEE)Operating Temperature (°C): 0ºC ~ 50ºCOperating Humidity (Non-condensing): 10% ~ 90%Storage Humidity (Non-condensing): 10% ~ 90% General:Tri-speed (10/100/1000BASE-T) copper interfacesAuto-negotiation for port speed and duplex modeAuto MDI/MDI-XDigital Diagnostic Monitoring (DDM) on 10G SFP+ port onlyVLANs:Supports 4K VLANPort-based VLANIEEE 802.1Q VLANGVRPVLAN TrunkingIEEE 802.1v Protocol-based VLANIP Subnet-based VLANMAC-based VLANTraffic SegmentationL2 Virtual Private NetworkQ-in-QVLAN TranslationL2 Protocol tunneling (xSTP, CDP, VTP & PVST+)CDP/PVST+ FilteringIGMP Snooping:IGMP v1/v2/v3 snoopingIGMP Proxy reportingIGMP FilteringIGMP ThrottlingIGMP Immediate LeaveIGMP QuerierOAMIEEE 802.3ah LinkIEEE 802.1ag Connectivity Fault Management :Connectivity checkLoopbackLinktraceITU-T Y.1731 Performance and Throughput Management:Frame DelayFrame Delay variationIPv4/IPv6 dual protocol stackSecurity:Port securityIEEE 802.1X port based and MAC based authentication Dynamic VLAN Assignment, QoS AssignmentMAC authentication Web authentication Voice VLANGuest VLANL2/L3/L4 Access Control ListPrivate VLANRADIUSPort IsolationWeb-based GUIManagement:CLI, WEB, TELNETL3:IPv4 static routeIPv6 static route Packet Forwarding Rate: 95MppsJumbo Frame (K): 9KBSwitching Capacity: 128Gbps
