Introduction; Key Features In The Device - Lancom GS-2124 User Manual

1 Introduction

The LANCOM Switch models LANCOM GS-2124 are managed layer-2 switches
with 20 Gigabit ports (for twisted pair cable – TP) and four Gigabit dual media
ports with TP/SFP, which meets the IEEE 802.3/u/x/z Gigabit, Fast Ethernet and
Ethernet specifications
The switch can be managed through RS-232 serial port via directly connec-
tion, or through Ethernet port using Telnet or Web-based management unit,
associated with SNMP agent. With the SNMP agent, the network administra-
tor can logon the switch to monitor, configure and control each port's activity
in a friendly way.
The overall network management is enhanced and the network efficiency is
also improved to accommodate high bandwidth applications. In addition, the
switch features comprehensive and useful function such as QoS (Quality of
Service), Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Secu-
rity, SNMP/RMON and IGMP Snooping capability via the intelligent software.
It is suitable for both metro-LAN and office application.
10/100/1000 Mbps TP is a standard Ethernet port that meets all IEEE 802.3/
u/x/z Gigabit, Fast Ethernet specifications. 1000 Mbps SFP Fiber transceiver is
a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000Base-
SX/LX standards.
1000 Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic
Wavelength Division Multiplexing (WDM) technology that transports bi-direc-
tional full duplex signal over a single fiber simultaneously.

Key Features in the Device

QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol)
standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active
VLANs and VLAN ID 1~4094.
