Four 10G SFP+ uplink ports. Backwards compatibility with RJ-45 ports.
Dedicated RJ-45 console port. Full CLI1, multilingual web GUI, SNMP MIB for remote NMS (D-View 7). Dual configuration files and dual software images.
Such as port mirroring, Spanning Tree Procol (STP), RSTP, MSTP, Link Aggregation.
Including IP interfaces, IPv6 Neighbor Discovery (ND), and IPv4/IPv6 Static Routing.
Up to 370W Power over Ethernet (PoE) power budget to power more devices.
Including ARP Spoofing Prevention, port security - up to 64 MAC addresses per port, IMP-Binding, and D-Link Safeguard Engine.
Capabilities like 802.11p Quality of Service, Bandwidth Control, Auto-Voice VLAN, and Surveillance Mode.
Support for STP, RSTP, and MSTP provides redundant links, prevents network loops, increases network reliability and minimises downtime for essential applications. These switches can even withstand temperatures between -5 to 50°C. Dual software images and configuration files allow the switch to quickly change between firmware versions and configurations to minimise downtime.
10G connections
Each switch in the series has four 10G SFP+ ports, which allows the most suitable media type to be chosen and mitigates network bottlenecks. The flexible uplink connections in both 1G/10G speeds deliver on data-intensive tasks.
D-Link’s exclusive Surveillance Mode provides a Web UI designed for video surveillance: it gives you an instant snapshot of your topology, makes features easy to access, and simplifies management of your surveillance network.
Layer 3 Lite
Including IP interfaces, IPv6 Neighbor Discovery (ND), ARP-Snooping Prevention, IGMP and MLD Snooping, LLDP and LLDP-MED. The DGS-1250 series also includes IPv4/IPv6 static routing capabilities for a scalable and more efficient network.
QoS
The series supports 802.11p Quality of Service to deliver data to devices based on the priority and type of traffic, and bandwidth Control to reduce unwanted network broadcast traffic. And the Auto-Voice and Auto-Surveillance VLAN features allow voice and video traffic to be automatically identified and prioritised.
All DGS-1250 series PoE switches support IEEE 802.3af/at with a high PoE power budget of 370W. This means more power to remote devices through single Ethernet cables without needing nearby power outlets, and results in faster and easier PoE deployments of VoiP phones, wireless APs or network cameras.
The D-Link Safeguard Engine helps protect against malicious traffic flooding the network in the event of a malicious attack. The series supports IMP-Binding which is an easy method to control nodes during IP conflicts and auditing issues, and it prevents ‘ARP spoofing’ and 'man-in-the-middle' malicious attacks.
Network security is further reinforced with ARP Inspection, DHCP Snooping, and a host of security and authentication features such as 802.1X port-based authentication, port security for 64 MAC addresses per port. The series also includes network protection functionalities like Access Control List, and DHCP Server Screening that only allows legitimate DHCP Server IP addresses on specific ports.
