Switch DGS-1510-28 L/me is the ideal solution for use in the networks of metro Ethernet. The switch features 24 10/100/1000BASE-T ports and 4 1000BASE-x SFP port. Protection against static electricity ensures resilience against unexpected electrical spikes, while a full Suite of security features and authentication protects the network from internal and external threats. Reliability All Ethernet ports of switch a DGS-1510-28 L/me has built-in protection against static electricity to 6 kV, which allows to protect the device from power surges. In case of interruption of power supply in the switch has an additional connector for connecting redundant power supply DPS-500A/DPS-500DC or power source DC voltage of 12 V. the Switch also supports Ethernet ring protection switching (ERPs, ITU-T G. 8032), whereby the recovery time after a failure of the ring within 50 milliseconds. In addition, the switch supports the functionality of the aggregation port based 802.1 ax, which enables you to combine multiple ports into a group, increasing bandwidth and redundancy for higher availability connection to ensure smooth operation and load balancing between multiple network devices. Service Triple Play The switch DGS-1510-28 L/me implemented a wide range of functions multicast level 2, including IGMP/MLD snooping, fast leave, and filtering. Support of this functionality provides the ability to work with IPTV-services, which are gaining popularity every year and are in great demand in the market. Application of functions of IGMP/mld snooping host-based enables the connection of multiple IPTV-subscribers to one network interface. Profiles, ISM VLAN allow users to quickly and easily assign or replace the pre-defined port settings for the subscription. Supports IGMP authentication, which can prevent rogue IPTV subscriptions by authenticating set top boxes. The quality of service Switch DGS-1510-28 L/me supports advanced functionality QoS (quality of service) to provide quality service to triple play. Packet classification can be based on various header fields or user-defined packet content to help administrators prioritize network traffic. Using the bandwidth management providers to determine the level of bandwidth of incoming/outgoing channel for each port with granularity down to 64 Kbps. Easy maintenance, efficient Troubleshooting Implemented in the switch to support the extended functionality of OAM (operation, administration and management) allows to considerably simplify the maintenance, finding and Troubleshooting. Using cable diagnostics you can remotely monitor the status of the network Ethernet cable and determine the location of a malfunction that allows the provider to reduce the cost of maintenance of equipment. Function connectivity fault management (CFM, IEEE 802.1 AG) is designed to monitor, search and Troubleshooting in Ethernet networks, allowing the service providers to perform a connection test, isolate problematic segments of the network and identify the users of such segments. Security and authentication The switch DGS-1510-28 L/I provides advanced functionality authentication user/device, including 802.1 x, access control based on MAC addresses (WT). The Mac Features allow network administrators to perform user authentication/device and manage the security of your network without having to install client software, which is very important, if installation on a customer's equipment is not possible. The authentication node provides the option to finely control access by each device in the network. For integration with billing systems and services supports radius. Provided in the switch DGS-1510-28 L/I function IP-Mac-port binding (IMPB) provides strong binding to addresses and interfaces, and to prevent ARP Spoofing – network protection against attacks such as man in the middle and the ARP Spoofing.
