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
