D-Link DES-2108/E [19/199] Performance features

24-port NWay Ethernet Switch User’s Guide

Introduction 5

♦ RS-232 DCE console port for setting up and managing the

Switch via a connection to a console terminal or PC using a

terminal emulation program.

Performance features

♦ Store and forward switching scheme capability to support

rate adaptation and protocol conversion.

♦ Full and half-duplex for both 10Mbps and 100Mbps

connections. The 1000BASE-SX 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 receive twisted-pair at each port.

♦ 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.

♦ 12K active MAC address entry table per device with

automatic learning and aging (10 to 9999 seconds).

♦ 12 MB packet buffer per device.
