The DXS-3130-28P Layer 3 Stackable Managed Switch is designed for secure connectivity in an enterprise or metro Ethernet access network and supports both multicasting and enhanced security, making it an ideal 10G/multi-Gigabit access layer solution. The DXS-3130-28P features 24 10G/multi-Gigabit 802.3bt 60W PoE++ ports and 4 10/25G SFP28 ports, offering a versatile and high-speed networking connection. The DXS-3130- 28P is equipped with 24 PoE ports, supporting 802.3af, 802.3at, and 802.3bt 60W PoE++ standards. It offers a default power budget of 790 watts, which can be expanded to 1440 watts with dual power supplies. Additionally, the switch features 4 10/25G SFP28 ports for enhanced speed and versatility. It also includes a USB 2.0 port, enabling direct booting of images and uploading of configuration files, as well as convenient storage of syslog files on a USB 2.0 device. Enhanced Network Reliability The DXS-3130-28P targets enterprises and metro Ethernet applications, and customers who require a high level of network security and maximum uptime. The DXS-3130-28P suppports hot-swappable internal redundant power supplies and incorporate essential reliability features to enhance network resilience, including 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP), 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and Broadcast Storm Control. G.8032 Ethernet Ring Protection Switching (ERPS) minimizes recovery time to 50 ms. For load sharing and redundancy backup in a switch cascading/server attachment configuration, the DXS-3130-28P provides dynamic 802.3ad Link Aggregation Port Trunking. Comprehensive Security The DXS-3130-28P provides users with the latest security features such as Multi-layer and Packet Content Access Control Lists (ACL), Storm Control, and IP-MAC-Port Binding (IMPB) with DHCP Snooping. The IP-MAC-Port Binding feature allows administrators to bind a source IP address with an associated MAC and define the port number to enhance user access control. With the DHCP Snooping feature, the switch automatically learns IP/ MAC pairs by snooping DHCP packets and saving them to the IMPB white list. Intelligent Fan Operation The DXS-3130-28P PoE models have built-in internal fans which can automatically start working to prevent the device from overheating. The fan speed will be gradually adjustedbetween 5 levels of cooling according to the operating temperature of the switch. Administrators can also configure the operation state of internal fans through Web UI or command line interface (CLI). Easy Access Control Policies The DXS-3130-28P supports authentication mechanisms such as 802.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control and easy deployment. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each host. Versatile Traffic Management The DXS-3130-28P implements a rich set of multi-layer QoS/CoS features to ensure that critical network services such as VoIP, video conferences, IPTV, and IP surveillance are always given high priority. Traffic Shaping features guarantee bandwidth for these services when the network is busy. L2 Multicast support enables the DXS-3130-28P to handle growing IPTV applications. Host-based IGMP/MLD Snooping allows multiple multicast subscribers per physical interface while ISM VLAN allows the switches to send multicast streams in a multicast VLAN to save bandwidth and to provide better security to the backbone network. The ISM VLAN profiles allow administrators to bind or replace the pre-defined multicast registration information to subscriber ports qui |
