Popis
Power & Value
The D-Link DGS-1250 Series Smart Managed Switches deliver real value as an
Enterprise Access and 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, QoS enablement,
and Advanced Layer-2 w/Lite Layer-3 features.
The DGS-1250 Series switches support 24 or 48 × 10/100/1000BASE-T ports,
with each switch also supporting an additional 4 × 10G SFP+ ports for optical
connections using multimode or single-mode SFP transceivers – enabling real
network horsepower at a value price.
Easy Maintenance, Less Downtime
The DGS-1250 Series supports Dual Image and Dual Configuration functionality,
as well as a Console Port, all of which make it easier to configure,
troubleshoot, and make other changes without interfering with network operation,
while full Command Line Interface (CLI) functionality enables remote
configuration, without the need for the Internet. And if a network issue ever
does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep
things running without interruptions or downtime.
Automatic Configuration
The DGS-1250 Series supports Auto Voice VLAN and Surveillance Mode, which allow
Voice and Video traffic to be automatically identified and handled differently
from regular network traffic. Auto Voice VLAN detects Voice over IP (VoIP)
traffic and automatically segments it from the rest of the network, increasing
security and allowing Quality of Service (QoS) to be applied.
Extensive Management and Advanced Features
The DGS-1250 Series comes equipped with IGMP snooping, Port Mirroring, Spanning
Tree Protocol (STP), and Link Aggregation Control Protocol (LACP). The IEEE
802.3× 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. And, because the switches can manage internal routing, the network
router can be assigned to handle external traffic.
Management Versatility
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 and display them onscreen for instant access.
