User manual D-LINK DEM-310GT BROCHURE

[. . . ] In addition to offering many versatile software functions, these switches also provide fiber uplinks to connect together small groups of users such as in different classrooms or departments spread across on a campus or between buildings. The DES-3000 series includes many features not found in other switches of the same class, such as IP-MAC-port binding user access screening, traffic segmentation and up to 255VLAN (802. 1Q). In addition, it also supports 802. 1x port-based/ MAC-based access control. [. . . ] In addition, it also supports 802. 1x port-based/ MAC-based access control. To prevent hackers from overwhelming the switch with unnecessary workload, the DES-3000 provides the CPU Interface Filtering function to filter out vicious packets before they reach the CPU. For Quality of Service, it supports 802. 1p Priority Queues and packet classification based on TOS, DSCP and MAC DA. To enhance network resilience, the DES-3000 provides 802. 1D Spanning Tree/802. 1w Rapid Spanning Tree, STP loopback detection, and broadcast storm control. It provides 802. 3ad Link Aggregation port trunks for load sharing/redundancy backup in a switch cascading or server attachment configuration. Network administrators can define throughput levels for each port to manage bandwidth. The bandwidth limiting feature provides fine granularity with the ability to define limits down to 64Kbps segments. When applied to control of broadcast storms infected with virus, this feature can limit the level of damage a virus attack can do to the network. distance 10km, 3. 3V operating voltage SFP transceiver, 1000BASE-SX standard, multi-mode fiber, max. distance 550m, 3. 3V operating voltage SFP transceiver, 1000BASE-SX standard, multi-mode fiber, max. distance 2km, 3. 3V operating voltage SFP transceiver, 1000BASE-LX standard, single-mode fiber, max. distance 50km, 3. 3V operating voltage SFP transceiver, 1000BASE-LX standard, single-mode fiber, max. distance 80km, 3. 3V operating voltage WDM SFP transceiver, 1000BASE-LX standard, single-mode fiber, max. distance 10 km, 3. 3V operating voltage, Tx wavelength 1550 nm, Rx wavelength 1310 nm WDM SFP transceiver, 1000BASE-LX standard, single-mode fiber, max. distance 10 km, 3. 3V operating voltage, Tx wavelength 1310 nm, Rx wavelength 1550 nm WDM SFP transceiver, 1000BASE-LX standard, single-mode fiber, max. distance 40 km, 3. 3V operating voltage, Tx wavelength 1550 nm, Rx wavelength 1310 nm WDM SFP transceiver, 1000BASE-LX standard, single-mode fiber, max.
