DLINK SWITCH 48PORT 10/100 LAN PORTS, 2x 10/100/1000Mbps COPPER PORTS, 2xSFP PORTS, LAYER 2, SMART MANAGED

The DES-1210-52/ME Metro Ethernet Switch is the perfect drop-in solution for for metro Ethernet applications. The DES-1210-52/ME provides 48 fast Ethernet ports while also including 4 Gigabit/SFP combo ports, which can provide up to 4Gbps uplink bandwidth, or provide support for dual Ethernet ring topology. Built-in surge protection ensures resilience against unexpected electrical spikes, while a full suite of security and authentication features keep your network safe from internal and external threats

Security & Authentication

The DES-1210-52/ME Metro Ethernet Switch supports 802.1X port-based/host-based access control, guest VLAN, and RADIUS/TACACS+ authentication for strict access control over the network. The IP-MAC-Port Binding feature allows administrators to bind a source IP address with an associated MAC and also to define the port number to enhance user access control. The built-in D-Link Safeguard Engine™ identifies and prioritizes packets to prevent malicious traffic from interrupting normal network flows and protects switch operation. In addition, the Access Control List (ACL) feature enhances network security and switch performance.

Resilience/Performance Enhancement

For mission critical environments, the DES-1210-52/ME Metro Ethernet Switch supports 802.1D-2004 edition, 802.1w and 802.1s Spanning Tree Protocols (STP). STP allows the switch to be configured with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in the event of any switch fail-over on the network. The switches also support 802.3ad link aggregation, which enables multiple ports to be grouped in parallel to form a single port, increasing bandwidth and redundancy for higher availability. These models feature 802.1p Quality of Service (QoS), allowing for real-time traffic classification into 8 priority levels mapped to 8 queues. Packet classification is based on TOS, DSCP, MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type, or user-defined packet content for flexible configuration for specific multimedia applications such as VoIP or IPTV.

Traffic & Bandwidth Control

Integrated bandwidth control allows network administrators to define the throughput levels for each port to manage bandwidth. It also provides fine granularity to define the ingress/egress traffic limits down to 64 Kbps segments. The DES-1210-52/ME also supports broadcast storm control, which minimizes the chances of a virus attack within the network, and port mirroring helps administrators facilitate traffic diagnostics and track switch performance. The DES-1210-52/ME also provides IGMP Snooping to prune multicast traffic and to optimize network performance.

Multicast Applications

The DES-1210-52/ME Metro Ethernet Switch feature 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 DES-1210-52/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 network. ISM VLAN profiles allow users to bind/replace the predefined multicast registration information to subscriber ports quickly and easily.

Management Capabilities

A web-based GUI provides a user-friendly interface and easy management, and DHCP auto-configuration gives administrators enhanced management features, allowing them to save configuration presets to a TFTP server. Individual switches can then retrieve their IP addresses from the server and load the preset configuration. Support for Link Layer Discovery Protocol (LLDP) allows a network device to advertise its identity and capabilities on the local network, which helps business better manage their network topology. Also, each port on these switches supports a cable diagnostic feature that helps detect cable related problems such as length or cable functionality issues.
