This switch allows SMBs to set up a secure and effective network at an affordable cost. With additional features such as enhanced network security, bandwidth control, and advanced management, the DES-3028P is a cost-effective switch that delivers proven results.Enhanced SecurityThe DES-3028P supports many security functions including Access Control List (ACL), 802.1x Port-Based/MAC-Based Access Control, 802.1x Guest VLAN, and RADIUS/TACACS+ authentication.The D-Link Safeguard Engine incorporates advanced mechanisms to detect an attack against the central processing unit of the switch and to take corrective measures on the attacking interface. When a Denial of Service attack is waged against any of the switches, the D-Link Safeguard Engine detects the threat and prevents the overload of the central processor, thus insuring network integrity and helping to maintain open network bandwidth channels.802.1Q VLANsThe DES-3028P provides support for 802.1Q VLANs for improved security and bandwidth utilization. VLANs provide a means of securing each broadcast domain, segregating them from each other. This in turn prevents users on one VLAN from gaining access to resources on other network segments. VLANs can be configured to segment departmental resources. For example, VLANs can be implemented on an SMB network to prevent the Marketing department from gaining access to secure resources in the Accounting department.QoS802.1p Priority Tagging helps streamline networks by placing a priority tag in a specified frame. When this frame is received by the switch, it is placed in a priority queue, enabling it to be prioritized ahead of other frames. 802.1p enables administrators to assign and designate traffic priority. This process helps applications such as VoIP and video conferencing to be delivered clear and jitter-free. DES-3028P supports a variety of different ways to prioritize the packets to ensure QoS in a busy network.802.3af Power over EthernetThe DES-3028P is able to supply power to PoE enabled devices. Each port on the DES-3028P can support up to 15.4W of power, budgeting a total of 195W throughout all 24 ports. This can eliminate the need to place devices near power outlets and help clean up loose wires and cables. For any devices that are not PoE enabled, PoE Adapters such as the D-Link DWL-P50 can be used to provide power to non-compliant devices.IGMP SnoopingBy passively snooping IGMP packets that are transferred between the DES-3028P and the IP multicast host, registration information is recorded and sorted into multicast groups. The switch can then intelligently forward traffic to only those ports that request multicast traffic. Adversely, without IGMP snooping, multicast traffic is treated like broadcast traffic, with packets forwarded to all ports causing network inefficiencies.ManagementThe DES-3028P supports a plethora of standards-based management protocols including SNMP, RMON, Telnet, web-based GUI, SSH/SSL protocols, and DHCP Relay Option 82. D-Link also simplifies management by featuring Single IP Management (SIM); a useful tool that allows multiple switches to be configured, monitored, and maintained from any workstation using a single IP Address. D-Link SIM stacking enables administrators to manage a virtual stack of up to 32 switches under a single IP address. D-Link SIM stacking is ideal for networks where switches may span across different buildings, but still require a shared IP address.�Features 24 802.3af PoE Ports Enhanced Features Including QoS, 4k Groups of 802.1Q VLANs, SIM Stackable Brings Advanced Enterprise Network Management Features to a Cost-Effective Level Support Standards-based Management Protocols Including SNMP, RMON, Telnet, Web-based GUI, SSH/SSL Protocols, and DHCP Relay Option 82Specifications Interface 10/100BASE-TX Ports - 24 10/100/1000BASE-T Ports - 4 Combo SFP - 2 802.3af PoE Support - per 10/100BASE-TX Port RS-232 Console Port - yes Performance Switch Capacity - 12.8Gbps 64-Byte Packet Fowarding Rate - 9.5Mbps MAC Address Table Size - 8K Packet Buffer - 512KB Flash Memory - 8MB Mini-Jumbo Frame - 2048 Bytes Diagnostic LED Indicators Power (Per Device) - yes Console (Per Device) - yes Link/Activity (Per Port) - yes Speed Indicator (Per Port) - yes PoE - yes Physical & Environmental Maximum Supplied PoE Power Per Device - 185W Power Consumption - 217W Power Input - 10 to 240 VAC, 50 to 60HZ Internal Universal Power Supply Dimensions (W x D x H) - 17.36” x 12.17” x 1.73” (441mm x 309mm x 44mm) Size - 19-inch Standard Rack-Mount Width, 1U Height Weight - 9.9lbs (4.5kg) Ventilation - 2 DC Fans Heat Dissipation - 742.7 BTU/hour MTBF - 196,003 hours Temperature - Operating: 32� to 104�F (0� to 40�C) - Storage: -40� to 158�F (-40� to 0�C) Operating Humidity - 5% ~ 95% Non-condensing EMI/EMC - FCC Class A, CE, C-Tick, VCCI Class A Safety - cUL, LVD Interface Options RJ-45 - 10BASE-T, 100BASE-TX, & 1000BASE-T LC - With Optional Standard Form-Factor Pluggable (SFP) Gigabit Transceivers Software Specifications L2 Features - IGMP Snooping v1, v2 (mac. 256 groups) - IGMP Snooping Fast Leave - 802.1D Spanning Tree - 802.1w Rapid Spanning Tree - 802.1s Multiple Spanning Tree - BPDU Filtering per Port - STP Loopback Detection - 802.3ad Link Aggregation (8 Ports per Group/ 6 Groups per Device) - Port Mirroring (One to One, Many to One) - Jumbo Frame (max. 2048 bytes) VLAN - Standard: 802.1Q - Static VLAN Groups: 4K - Dynamic VLAN Groups: 200 - GVRP Quality of Service (QoS) - Quality of Service (QoS) - 802.1p Priority Queues: 4 Queues - Packet Classification Based on: - Switch Port - VLAN ID - TCP/UDP Port Number - MAC Address - IPv4 - 802.1p Priority - TOS - DSCP - User Defined Packet Content - Protocol Type - Support WRR/ Strict Mode Access Control List (Maximum 256 Profiles/Rules) - Multi-Layer ACL based on: - Switch Port - VLAN ID - MAC Address - IPv4 - 802.1p Priority - TOS - DSCP - Protocol Type - TCP/UDP Port Number - Time-Based ACL - User Defined Packet Content Network Access/Security - RADIUS/TACACS+ Authentication for Management Access - RADIUS Accounting for Management Access - Port Security (max. 16 MAC entries per port) - 802.1X Port-based Access Control - 802.1X MAC-based Access Control - 802.1X Guest VLAN - SSH v1, v2 / SSL v3 - CPU Interface Filtering - Traffic Segmentation - Broadcast Storm Control - D-Link Safeguard Engine Bandwidth Control - Rate Limit According to Network Speed : - Under 2Mbps: in step of 64KB - Under 100Mbps; in step of 1MB - Above 100Mbps: in step 8MB Management - D-Link Single IP Management (SIM) v1.6 - Web-based GUI - CLI (Command Line Interface) - Telnet client/server - TFTP client - SNMP v1, v2c, v3 - RMON v1, v2 - BOOTP/DHCP Client - SNTP - SYSLOG - Dual Image - Port Description - Web GUI Traffic/ CPU Monitoring - SNMP Trap on MAC Notification - DHCP Auto Configuration - DHCP Relay - DHCP Relay Option 82 - SMTP Client (E-mail Notification) MIB Support - MIBII (RFC 1213) - Bridge MIB (RFC 1493) - SNMP v2 MIB (RFC 1907) - RMON v2 MIB (RFC 1757, 2819) - Ether-like MIB (RFC 1643, 2358, 2665) - 802.1p MIB (RFC 2674) - IF MIB (RFC 2233, 2863) - RADIUS Authentication Client MIB (RFC 2618) - RADIUS Accounting Client MIB (2620) - Ping & TRACEROUTE MIB (RFC 2925) - Private MIB Warranty Information Warranty - Limited Lifetime Ordering Information Part Number - Description DES-3028P - Managed 24-Port 10/100 PoE Switch, L2 Stackable, 4 Gigabit Ports, and 2 Combo SFP Slots DES-3028 - Managed 24-Port 10/100 Switch, L2 Stackable, 4 Gigabit Ports, and 2 Combo SFP Slots DES-3052 - Managed 48-Port 10/100 Switch, L2 Stackable, 4 Gigabit Ports, and 2 Combo SFP Slots DES-3052P - Managed 48-Port 10/100 PoE Switch, L2 Stackable, 4 Gigabit Ports, and 2 Combo SFP Slots DEM-310GT - 1000BASE-LX, Single-mode, 10km DEM-311GT - 1000BASE-SX, Multi-mode, 500m DEM-211 - 100BASE-FX, Multi-mode, 2km Detalii producator
