D-Link DGS-1250-52XMP Smart switch 48x Gb PoE+, 4x 1G/10G SFP+, 370W
D-Link DGS-1250-52XMP je L2/L3 Gigabit Smart Managed switch osazený 24 porty 10/100/1000Base-T RJ-45 s podporou napájení 802.3at PoE+ (max. 30W na port) a 4 dvourychlostními 1G/10G SFP+ porty pro uplink nebo pro připojení serverů, s podporou Gigabit SFP a 10G SFP+ transceiverů. Celkový PoE výkon switche je 370W.
Série DGS-1250 disponuje komplexní sadou L2 funkcí (např. VLAN, detekce smyček, agregace linek, zrcadlení portů, Spanning Tree protokoly STP/RSTP/MSTP, IGMP/MLD Snooping atd.) a L3 statickým routingem (4 IP interfaces, max. 124/50 IPv4/IPv6 statických záznamů v tabulce). Bezpečnostní funkce (ACL, 802.1x, MAC Security, IP-MAC-Port binding atd.) a funkce řízení kvality služeb QoS zajišťují spolehlivý provoz sítě). Správa přepínače je přes webové rozhraní nebo pomocí SNMP příkazů. Pro kamerové systémy je určen Surveillance Mode režim webového rozhraní a funkce Auto-Surveillance VLAN pro automatické přiřazení prvků kamerových systémů do oddělené VLAN s vyšší prioritou. Pro centrální správu sítě je k dispozici bezplatný SW nástroj D-Link Network Assistant (DNA) a pokročilá platforma D-View7.
Série DGS-1250 je cenově efektivní 10G řešení jako páteřní switche pro malé a střední firmy (SMB) nebo jako přístupové switche v podnikových (Enterprise) sítích.
Na switche DGS-1250 je záruka 5 let.

Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)
VLAN Translation Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN
Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers
Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs

Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2 Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 2K multicast groups (source-specific multicasting is also supported)

Security ecure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (SCP) also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
IEEE 802.1X (Authenticator role) 802.1X: Remote Authentication Dial-In User Service (RADIUS) authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions
Supports time-based 802.1X; dynamic VLAN assignment; MAC authentication
IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)
Web-based authentication Web-based authentication provides network admission control through web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops
STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers.
IP Source Guard (IPSG) When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DH

IP Source Guard (IPSG) When IPSG is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing
Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks
IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability
