Features
The DES-3250TG Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously.
Switch features include:
•Store and forward switching scheme.
•Full and half-duplex for both 10Mbps and 100Mbps connections. The front-port Gigabit Ethernet module operates at full duplex only. Full duplex allows the switch port to simultaneously transmit and receive data, and only works with connections to full-duplex capable end stations and switches. Connections to hubs must take place at half-duplex.
•Auto-polarity detection and correction of incorrect polarity on the transmit and receive twisted-pair at each port.
•IEEE 802.3z compliant for Mini GBIC ports (optional module).
•IEEE 802.3ab compliant for 1000BASE-T (Copper) Gigabit ports (optional module).
•Data forwarding rate 14,880 pps per port at 100% of wire-speed for 10Mbps speed.
•Data forwarding rate 148,800 pps per port at 100% of wire-speed for 100Mbps speed.
•Data filtering rate eliminates all error packets, runts, etc. at 14,880 pps per port at 100% of wire-speed for 10Mbps speed.
•Data filtering rate eliminates all error packets, runts, etc. at 148,800 pps per port at 100% of wire-speed for 100Mbps speed.
•8K active MAC address entry table per device with automatic learning and aging (10 to 1,000,000 seconds).
•64 MB packet buffer per device.
•Supports Port Mirroring.
•Supports Port Trunking.
•802.1D Spanning Tree support.
•802.1Q Tagged VLAN support – up to 255 VLANs per device (one VLAN is reserved for internal use).
•GVRP – (GARP VLAN Registration Protocol) support for dynamic VLAN registration.
•802.1p Priority support with 4 priority queues.
•IGMP Snooping support.
Ports
•Forty-eight high-performance NWay ports all operating at 10/100 Mbps for connecting to end stations, servers and hubs.
•All 48 10/100 UTP ports can auto-negotiate (NWay) between 10Mbps/100Mbps, half-duplex or full duplex.
•One front panel slide-in module interface for a 2-port 1000BASE-T module (provided) and one front panel slide-in module interface for a 2-port Mini GBIC Gigabit Ethernet module (optional). Please note that although these two front
