Introduction; Key Features In The Device - Lancom GS-1224P Manual

1 Introduction

The LANCOM GS-1224 is a websmart layer-2 switch with 20 Gigabit ports (for
twisted pair cable – TP) and four Gigabit dual media ports with TP/SFP, which
meets the IEEE 802.3 Gigabit, Fast Ethernet and Ethernet specifications.
The LANCOM Switches can be configured through WEBconfig.
The overall network management is enhanced and the network efficiency is
also improved to accommodate high bandwidths. In addition, the switch fea-
tures comprehensive and useful function such as QoS (Quality of Service),
Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Security, SNMP
and IGMP Snooping capability via the intelligent software. It is suitable for
both metro-LAN and office application.
The LANCOM GS-1224P switch also complies with IEEE 802.3af, its advanced
auto-sensing algorithm enables providing power devices (PD) discovery, clas-
sification, current limit, and other necessary functions. It also supports high
safety with short circuit protection and power-out auto-detection to PD.
The 10/100/1000 Mbps TP-Ports are standard Ethernet ports that meets all
IEEE 802.3/u/x/z (Gigabit and Fast Ethernet) specifications.
The 1000 Mbps SFP Fiber transceiver are Gigabit Ethernet ports that fully
complies with all IEEE 802.3z and 1000Base-SX/LX standards. The Single
Fiber WDM (BiDi) transceiver is designed with an optic Wavelength Division
Multiplexing (WDM) technology that transports bi-directional full duplex sig-
nal 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 IEEE 802.1q Tag VLAN. Support 24 active
VLANs and VLAN ID 1~4094.
