Tanımlama: The DGS-1210/ME Series Metro Ethernet Switches are a family of Ethernet switches ideal for Metro Ethernet applications. These Metro Ethernet Switches provide 8/16/24/48 copper connections on upgraded Gigabit Ethernet ports, along with Gigabit SFP ports for improved uplink bandwidth. Surge protection ensures resilience against unexpected electrical spikes, while a full suite of security and management features keeps your network safe from internal and external threats. Gigabit Performance The DGS-1210/ME Series all come with 10/100/1000 Mbps Ethernet downlink ports for superior Gigabit performance for your network. All models offr Gigabit SFP uplink ports and the DGS-1210-10P/ME , DGS-1210-28P/ME, DGS-1210-52P/ME, and DGS-1210-54MP/ME also offr Power-over-Ethernet (PoE) so network devices such as PoE IP cameras can be installed in remote locations without immediate access to power outlets. Simply use an Ethernet cable to connect to these devices at the deployment location and it can act as a conduit not only for data, but for power as well. Effient and Resilient For mission critical environments, the DGS-1210/ME Series Metro Ethernet Switches support 802.1D 2004 edition, 802.1w, and 802.1s Spanning Tree Protocols (STP). STP allows the switch to be confiured with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in emergency situations. 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 traff classifiation into Weighted Round Robin (WRR) and strict priority levels mapped to 8 queues. Packet classifiation is based on TOS, DSCP, MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type, or user-defied packet content for flxible confiuration for specifi multimedia applications such as VoIP or IPTV Security & Authentication DGS-1210/ME Series Metro Ethernet Switches support 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 defie the port number to enhance user access control. The builtin D-Link Safeguard Engine™ protects the CPU from broadcast/multicast/ unicast floding 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 web-based GUI provides a user-friendly interface and easy management, and DHCP auto-confiuration gives administrators enhanced management features, allowing them to save confiuration presets to a TFTP server. Individual switches can then retrieve their IP addresses from the server and load the preset confiuration. Support for Link Layer Discovery Protocol (LLDP) allows a network device to advertise its identity and capabilities on the local network, which helps businesses 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, so the administrator can quickly identify and fi this problem. Traffic & Bandwidth Control Integrated bandwidth control allows network administrators to defie the throughput levels for each port to manage bandwidth. It provides minimum granularity of 64 Kbps, ingress control for port and flw-based bandwidth control. The DGS-1210/ME Series also supports traff control, which optimizes performance by dropping packets beyond the threshold, and port mirroring helps administrators facilitate traff diagnostics and track switch performance. The DGS-1210/ME Series also provides IGMP snooping with IGMP authentication to prune multicast traff and to optimize network performance. Multicast Applications The DGS-1210/ME Series Metro Ethernet Switches feature a full set of L2 multicast functions, including IGMP snooping, IGMP fitering, fast leave, and multicast traff confiuration for specifi ports. With L2 multicast support, the DGS-1210/ME Series 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 profies allow users to bind/replace the predefied multicast registration information to subscriber ports quickly and easily.
