Metro Ethernet Managed Switch with 24 10/100/1000Base-T PoE ports, 24 10/100/1000Base-T ports and 4 1000Base-X SFP ports
תאור:
The D-Link DGS-1210-52P/ME Smart Switch is designed for Metro Ethernet applications. Surge protection, advanced Layer 2 functions, and a suite of security and management tools make the DGS-1210-52P/ME switch ideal for Metro Ethernet applications. The DGS-1210-52P/ME switch is equipped with 48 10/100/1000Base-T ports (24 10/100/1000Base-T ports support PoE) and 4 1000Base-X SFP ports and features Power over Ethernet (PoE), allowing compatible devices to be installed and powered in remote locations without immediate access to power outlets.
 
Efficient and Resilient
For mission critical environments, the DGS-1210-52P/ME switch supports IEEE 802.1D 2004 edition, 802.1w, and 802.1s Spanning Tree Protocols (STP). The Spanning Tree Protocol allows the switches to participate in Spanning Tree topology, providing an alternative Layer 2 path in the event of a network failover. The switch also supports IEEE 802.3ad link aggregation, which enables multiple ports to be grouped to form a single virtual port, increasing bandwidth and redundancy for higher availability. The DGS-1210-52P/ME furthermore features IEEE 802.1p Quality of Service (QoS), allowing for real-time traffic classification into Weighted Round Robin (WRR) and strict priority levels mapped to 8 queues. Advanced traffic classification parameters allow the network to be tuned for flexible configurations for specific multimedia applications such as VoIP or IPTV.
 
Security & Authentication
The DGS-1210-52P/ME switch supports IEEE 802.1X port-based/host-based access control, guest VLAN, and RADIUS/TACACS+ authentication for strict access control to the network. The IP-MAC-Port Binding (IMPB) feature allows administrators to associate a source IP address with a designated MAC address and also offers the flexibility to define the port number to enhance user access control. The built-in D-Link Safeguard Engine protects the CPU from broadcast, multicast, and unicast flooding by automatically trapping packets and logging events in these situations. In addition, the Access Control List (ACL) feature enhances network security and switch performance.
 
Management Capabilities
A user-friendly web interface gives administrators access to advanced management features such as DHCP auto-configuration. This enables switches to load their configuration from a TFTP server once they have been assigned an IP address, allowing central management of device configurations. The switch supports Link Layer Discovery Protocol (LLDP), which advertises the device’s capabilities and identity to the local network, allowing administrators to better manage their network topology. Each port also supports cable diagnostics, which can be used to troubleshoot cable length and functionality problems remotely, resulting in lower management overheads.
 
Traffic & Bandwidth Control
Integrated bandwidth control allows network administrators to define the throughput levels for ingress and egress bandwidth. It provides a minimum granularity of 64 Kbps for ingress port and flow-based bandwidth control, and a minimum granularity of 64 Kbps for egress queue bandwidth.
The DGS-1210-52P/ME switch also supports traffic control, which optimizes performance by dropping packets when exceeding a set threshold, while port mirroring helps administrators facilitate traffic diagnostics and track network performance. The DGS-1210-52P/ME switch also provides IGMP snooping with IGMP authentication to prune multicast traffic and to optimize available bandwidth.
 
Multicast Applications
The DGS-1210-52P/ME switch features a full set of L2 multicast functions, including IGMP snooping, IGMP filtering, fast leave, and multicast traffic configuration for specific ports. With L2 multicast support, the DGS-1210-52P/ME is ready and capable of handling growing IPTV applications. Host-based IGMP/MLD snooping allows for multiple multicast subscribers per physical interface, and ISM VLAN sends multicast streams in a multicast VLAN, saving bandwidth on the backbone. Additionally, ISM VLAN profiles allow users to bind or replace the predefined multicast registration information to subscriber ports quickly and easily.
