Descrierea produsului
D-Link, DGS-1500-20 Switch 16-port 10/100/1000, 4-port SFP, SmartPro. Virtual stacking with SIM (Single IP Management)Gigabit speeds on all portsMore port-count than the standard Smart familySecurity features usually found only in high-end modelsSafeGuard Engine to protect the network from excessive trafficAuto Voice VLAN for easy integration of IP phones in your networkAuto Surveillance VLAN for smooth video from IP camerasEasy configuration with a Web GUIPower-saving designD-Link’s DGS-1500 SmartPro family of switches is designed for small/medium businesses who require functions like L3 Static Routing and Single IP Management (Virtual Stacking) without upgrading to a managed switch. The family integrates advanced management and security functions that are similar to those of a managed switch, but less complex. The switches feature D-Link Green 3.0 technology which enables significant power savings. Additionally, the DGS-1500-28P’s 10/100/1000 Mbps ports are PoE-enabled, offering ease-of-use and green features such as Time-based PoE, which enables the power to be shut off at a predetermined time. Compliant with 802.3af and 802.3at, these switches are capable of feeding power to devices of up to 30 Watts. Management options for the switches include SNMP, Web Management, SmartConsole Utility, and Compact CLI. The family also supports ACL filtering and D-Link’s Safeguard Engine. The DGS-1500 family uses Auto Voice VLAN, ensuring higher priority for voice traffic. The DGS-1500-20 and DGS-1500-28 are both fanless which allows them to emit less heat and noise than a standard switch, making them suitable for office environments. The DGS-1500-28P and DGS-1500-52 both feature smart fans which use a thermal sensor that can detect temperature change, the smart fans can react accordingly by utilising different fan speeds for different temperatures.   Energy Saving D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DGS-1500 family implements D-Link Green Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and cable length detection. The power-saving features include being able to schedule when to turn off LEDs and ports when not in use, and when to make the switch enter hibernation mode. The switches can also detect the length of connected cables to automatically adjust power usage by saving energy on shorter cable connections of up to 20 meters. The switches can also support power-saving by link status, which drastically reduces power consumption by automatically toggling ports without a link to sleep mode. The DGS-1500-28P and DGS-1500-52 both feature built in smart fans. Using a thermal sensor that can detect temperature change, the fans can react accordingly by utilizing different fan speeds for different temperatures. The Smart Fan feature enables the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.   Advanced Features The DGS-1500 family features advanced features such as Virtual Stacking and Layer 3 features like Static Routing. Virtual Stacking reduces the number of IP addresses needed on a network by configuring up to 32 devices to appear as a single unit with one IP address. This simplifies network management for small workgroups and allows for switches to be added without special cabling.   Extensive Layer 2 Features These switches are equipped with a complete lineup of Layer 2 features including IGMP Snooping, Port Mirroring, Spanning Tree, and Link Layer Discovery Protocol (LLDP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfer. At 2000 Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port or VLAN and automatically shut down the affected port or VLAN. The Cable Diagnostic feature, designed primarily for administrators and customer service representatives, can rapidly discover the type of error on cables and determine the cable quality.   QoS, Bandwidth Control The DGS-1500 family supports Auto Surveillance VLAN (ASV), and Auto Voice VLAN which are best suited for VoIP and video surveillance deployments. Auto Surveillance VLAN is a new, industry-leading technology built into D-Link SmartPro family. This technology consolidates data and surveillance video transmission through a single SmartPro switch, thus sparing businesses the expense of maintaining dedicated hardware and facilities. ASV also ensures the quality of real-time video for monitoring and control without compromising the transmission of conventional network data. The Auto Voice VLAN technology enhances the VoIP service by automatically placing voice traffic from an IP phone to an assigned VLAN. With higher priority and individual VLAN, these features guarantee the quality and security of VoIP traffic. Furthermore, the DSCP markings on Ethernet packets enable different levels of service to be assigned to network traffic. As a result, these voice and video packets take precedence over other packets. In addition, with Bandwidth Control, network administrators can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.   Secure your Network D-Link’s innovative Safeguard Engine protects the switches against traffic flooding caused by virus attacks. The switches also support 802.1X port-based authentication, allowing the network to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and helps to protect the internal IT network by screening traffic based on MAC or IP addresses. The DGS 1500 SmartPro family includes ARP Spoofing Prevention, which protects from attacks on the Ethernet network that may allow an intruder to sniff data frames, modify traffic, or bring traffic to a halt altogether by sending fake ARP messages to the network. To prevent ARP Spoofing attacks, the switch uses Packet Control ACLs to block invalid packets that contain fake ARP messages. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.   Versatile Management The DGS-1500 SmartPro family provides a SmartConsole utility and a web-based management interface that enables administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC. It also simplifies the initial setup of the Smart Switches. Switches within the same L2 network segment that are connected to the user’s PC are displayed on screen for instant access. This allows extensive switch configuration and basic setup of discovered devices including password changes and firmware upgrades. The DGS-1500 family also supports D-View 6.0 and Compact Command Line Interface (CLI) through Telnet. D-View 6.0 is a Network Management System that allows for the central management of critical network characteristics such as availability, reliability, resilience, and security. CLI management of the switches is possible via Telnet. This makes it possible to adjust basic settings, passwords, configuration files, and firmware with ease.  StackabilityVirtual Stacking/Clustering of up to 32 unitsSupports D-Link Single IP Management (SIM)   L2 FeaturesMAC Address Table16 KFlow Control802.3x Flow ControlHOL Blocking PreventionIGMP SnoopingIGMP v1/v2 SnoopingSupports 256 IGMP groupsSupports at least 64 static multicast addressesIGMP per VLANSupports IGMP Snooping QuerierSpanning Tree Protocol802.1D STP802.1w RSTPLoopback Detection802.3ad Link AggregationDGS-1500-20: Max. 10 groups per device/8 ports per groupDGS-1500-28/DGS-1500-28P: Max. 14 groups per device/8 ports per groupDGS-1500-52: Max. 26 groups per device/8 ports per groupPort MirroringOne-to-OneMany-to-OneSupports Mirroring for Tx/Rx/BothCable DiagnosticsConfigurable MDI/MDIXMulticast FilteringForwards all unregistered groupsFilters all unregistered groupsJumbo frame up to 10,000 bytesLLDPLLDP-MEDL2 Multicast Filtering   VLAN802.1QVLAN GroupMax. 4K static VLAN groupsMax. 4094 VIDsGVRPUp to 256 dynamic VLANsAsymmetric VLANAuto Voice VLANMax. 10 user defined OUIMax. 8 default OUIAuto Surveillance VLAN   QoS (Quality of Service)802.1p Quality of Service4 queues per portQueue HandlingStrictWeighted Round Robin (WRR)CoS based on802.1p Priority QueuesDSCPToS5IPv6 Traffic Class1IPv6 flow label1TCP/UDP port1Bandwidth Control-Port-based (Ingress/Egress, min. granularity for 10/100 is 64 Kb/s and 10/100/1000 is 64 Kb/s)  L3 FeaturesARP64 Static ARPSupports Gratuitous ARPIPv6 Neighbor Discovery (ND)1IP InterfaceSupports 4 interfaces  L3 RoutingDefault RoutingStatic Routing32 IPv4 Static Route EntriesMax. 128 IPv4 Host Routes  Access Control List (ACL)DGS-1500-20/28/28P:Max. 50 profilesMax. 200 rules shared by profilesEach rule can be associated to a single port or multiple portsDGS-1500-52:Max. 50 profilesMax. 450 rules shared by profilesEach rule can only be associated to a single portACL based onMAC AddressIPv4 Address (ICMP/IGMP/TCP/UDP)802.1pDSCP Ethernet typeACL ActionsPermitDeny  Security802.1X Port-based Access ControlPort SecuritySupports up to 64 MAC addresses per portBroadcast/Multicast/Unicast Storm ControlD-Link Safeguard EngineDHCP Server ScreeningIP-MAC-Port Binding1Supports 512 address binding entriesARP modeSupports DHCP SnoopingARP Spoofing PreventionMax. 64 entriesTraffic SegmentationSSLSupports v1/v2/v3Supports IPv61  AAA802.1x AuthenticationSupports local/RADIUS databaseSupports Port-based access controlSupports EAP, OTP, TLS, TTLS, PEAPIPv6 RADIUS Server1   MIB1213 MIB II1493 Bridge MIB1907 SNMP v2 MIB1215 Trap Convention MIB2233 Interface Group MIBD-Link Private MIBLLDP MIBPower-Ethernet MIB   RFC Standard ComplianceRFC 783 TFTPRFC 854 Telnet ServerRFC 951 BootP/DHCP ClientRFC 1157 SNMP v1, v2, v3RFC 1213 MIB IIRFC 1215 MIB Traps ConventionRFC 1350 TFTPRFC 1493 Bridge MIBRFC 1769 SNTPRFC 1542 BootP/DHCP ClientRFC 1901 SNMP v1, v2, v3RFC 1907 SNMP v2 MIBRFC 1908 SNMP v1, v2, v3RFC 2068 FCSRFC 2131 BootP/DHCP ClientRFC 2138 RADIUS AuthenticationRFC 2139 RADIUS AuthenticationRFC 2233 Interface Group MIBRFC-2246 SSLRFC 2475RFC 2570 SNMP v1, v2, v3RFC 2575 SNMP v1, v2, v3RFC 2598 CoSRFC 2616 FCSRFC 2618 RADIUS AuthenticationRFC 2819 RMON v1RFC 2865 RADIUS AuthenticationRFC 3164 System LogRFC 3195 System LogRFC 3411-17 SNMPRFC 3621 Power Ethernet MIB   OAMCable DiagnosticsFactory Reset   ManagementWeb-based GUISingle IP ManagementCompact CLITelnet ServerTFTP ClientConfigurable MDI/MDIXSNMPSupports v1/v2/v3SNMP TrapTrap for SmartConsole UtilitySystem LogMax. 500 log entriesBootP/DHCP ClientSNTPICMP v61IPv4/v6 Dual Stack1DHCP Auto ConfigurationDebug commandTime SettingSNTPRMON1Trusted HostTime-based PoEUser AccountUpload/Download Configuratiion fileBackup/Upgrade firmwareSmart Wizard   GreenPower Saving byLink StatusCable LengthLED shutoffPort StandbySystem Hibernation  CertificationIPv6 Core Ready Logo Phase II1   1 IPv6 support will be available in a future release in 2012Detalii producator
