D-Link DES-3250TG Standalone Layer 2 Switch
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
