Power & Value\n The D-Link DGS-1250 Series Smart Managed Switches deliver real value as an Enterprise Access & Small-to-Medium Business (SMB) Access/ Aggregation solution. They provide a range of physical interfaces (including a Console Port w/full CLI), multiple management interfaces, 11 Web languages, Qo S enablement, & Advanced Layer-2 w/ Lite Layer-3 features. \n\n The DGS-1250 Series switches support 24 or 48 x 10/100/1000BASE-T ports, with each switch also supporting an additional 4 x 10G SFP+ ports for optical connections using multimode or single-mode SFP transceivers " enabling real network horsepower at a value price.\n\n Easy Maintenance, Less Downtime\n The DGS-1250 Series supports Dual Image & Dual Configuration functionality, as well as a Console Port, all of which make it easier to configure, troubleshoot, & make other changes without interfering with network operation, while full Command Line Interface (CLI) functionality enables remote configuration, without the need for the Internet. & if a network issue ever does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep things running without interruptions or downtime.\n\n Automatic Configuration\n The DGS-1250 Series supports Auto Voice VLAN & Surveillance Mode, which allow Voice & Video traffic to be automatically identified & handled differently from regular network traffic. Auto Voice VLAN detects Voice over IP (Vo IP) traffic & automatically segments it from the rest of the network, increasing security & allowing Quality of Service (Qo S) to be applied.\n\n Extensive Management & Advanced Features\n The DGS-1250 Series comes with IGMP snooping, Port Mirroring, Spanning Tree Protocol (STP), & Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfers. The series also supports advanced features such as Static Routing, which allows for communication between different user groups in different VLAN segments in a network.\n\n Management Versatility\n The DGS-1250 Series comes with the D-Link Network Assistant (DNA) utility so admins can remotely control their network to the port level. DNA allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment & display them onscreen for instant access.\n\n- 24 x 10/100/1000BASE-T ports\n- 4 x 10G SFP+ ports\n- Lite L3 Static Routing\n- Advanced security features, IMPB, 802.1X Authentication\n- Dual Image & Configuration\n- Supports STP/RSTP/MSTP\n- Full CLI\n- Qo S Enablement\n- 11 Web Languages Feature Feature Value Switch type Managed Switch layer L3 Quality of Service (Qo S) support Y Web-based management YARP inspection Y Configuring Location Settings (CLI)YSystem event log YMIB support RFC2893, RFC4213, RFC4291, RFC2464, RFC2462, RFC4862, RFC2461, RFC4861, RFC2573, RFC1321, RFC2284, RFC2865, RFC2716, RFC3580, RFC826, RFC2463, RFC4443, RFC792, RFC793, RFC768, RFC791, RFC2389, RFC4113, RFC4022, RFC2618, RFC2674, RFC1398, RFC1643, RFC1650, RFC2358, RFC2665, RFC2021, RFC271, RFC1757, RFC2819, RFC1442, RFC1901, RFC1902, RFC1903, RFC1904, RFC1905, RFC1906, RFC1907, RFC1908, RFC2578, RFC3418, RFC2573, RFC2575, RFC2576, RFC1212, RFC1213, RFC1215, RFC1493, RFC1157, RFC2620, Basic switching RJ-45 Ethernet ports quantity 24 Basic switching RJ-45 Ethernet ports type Gigabit Ethernet (10/100/1000)SFP+ module slots quantity 4 Console port RJ-45 Networking standards IEEE 802.1D, IEEE 802.1Q, IEEE 802.1p, IEEE 802.1s, IEEE 802.1w, IEEE 802.3, IEEE 802.3ab, IEEE 802.3ad, IEEE 802.3ae, IEEE 802.3az, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z 10G support Y Copper ethernet cabling technology 10BASE-T, 100BASE-TX, 1000BASE-TCable types supported Cat 5, Cat 5e Port mirroring Y Full duplex Y Flow control support Y Link aggregation Y Broadcast storm control Y Auto MDI/MDI-XYSpanning tree protocol Y Head-of-line (HOL) blocking YVLAN support Y Virtual LAN features Voice VLANNumber of VLANs 4094 Fiber ethernet cabling technology 100BASE-FX, 1000BASE-LHX, 1000BASE-X, 1000BASE'LX, 1000BASE'SX, 1000BASE'ZXMAC address table 16000 entries Switching capacity 128 Gbit/s Forwarding rate 95.24 Mpps Store-&-forward Y Static route Y Number of static routes 124 Jumbo frames support Y Jumbo frames 12000 Packet buffer memory 12 MBDHCP features DHCP client, DHCP server, DHCP snooping Access Control List (ACL)YAccess Control List (ACL) rules 768IGMP snooping Y Security algorithms EAP, MD5, PEAP, SSH, SSL/TLS, TTLSLoop protection YIP-MAC-Port binding Y Queue scheduling algorithms Weighted Round Robin (WRR) Multicast support Y Product colour Black LED indicators Activity, Link, Power, Speed Electromagnetic compatibility CE A, VCCI A, FCC A, IC, BSMICertification CB, UL, BSMI, CCCMemory type DDR3-SDRAMInternal memory 2048 MBFlash memory 64 MBNoise level 47.6 d B Firmware upgradeable Y Mean time between failures (MTBF)743482.45 h Power supply included YAC input voltage 100
