D-Link DGS-3000-28XS network switch

Network switch D-Link DGS-3000-28XS

Gigabit switches of the DGS-3000 series are included in the line of D-Link level 2 managed switches and are intended for use in Metro Ethernet networks and campus networks. The DGS-3000-28XS switch is equipped with 24 1000Base-X SFP ports and 4 10GBase-X SFP + ports.

Reliability

The DGS-3000-28XS switch supports Ethernet Ring Protection Switching (ERPS, ITU-T G.8032) technology, thanks to which the recovery time of the ring after a failure does not exceed 50 ms. In addition, the switch supports port aggregation functionality based on the 802.1AX and 802.3ad standards, the use of which allows you to combine several ports into a group, while increasing the bandwidth and increasing the fault tolerance of connections to ensure uninterrupted operation and load distribution among several network devices.

Quality of Service (QoS)

The DGS-3000-28XS switch provides a set of multi-level QoS / CoS functions to ensure that delay-critical network services such as VoIP, video conferencing, IPTV and video surveillance will be served with due priority. Packet classification is based on various header fields or user-defined packet content, enabling traffic prioritization.

Access Management Policies

The DGS-3000-28XS switch supports authentication mechanisms such as 802.1X, Web-based access control (WAC) and MAC-based access control, providing strict access control to network resources. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each node.

Management

The D-Link Single IP Management (SIM) function simplifies and speeds up management tasks, allowing you to configure, monitor, and service multiple switches by connecting to one IP address from any computer with Web browser support. This technology allows you to manage individual physical switches in a virtual stack using a single IP address.
