Preface
Thank you for your confidence in us!
LANCOM Switches are ideally suited to small, medium- sized and performance
networks in business environments.
The LANCOM GS-1224 switch features 20 Gigabit-Ethernet and four combo
ports (TP/SFP), it integrates perfectly into LANCOM's Advanced Routing und
Forwarding and it supports up to 24 active VLANs. It uses bandwidth control
to prioritize the data traffic according to predefined criteria (e.g. voice data or
certain ports).
The LANCOM Switch can be managed with the clearly structured Webconfig
and is supported by the LANCOM Management Tools (LANconfig and

LANCOM GS-1224
쮿 Chapter 1: Introduction
1Introduction
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 features 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 10/100/1000 Mbps TP-Ports are standard Ethernet ports that meets all
IEEE 802.3/u/x/z (Gigabit and Fast Ethernet) specifications.
EN
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 signal over a single fiber simultaneously.
1.1 Key Features in the Device
쮿 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.
쮿 Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol)
standards.
쮿 VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 24 active
VLANs and VLAN ID 1~4094.
쮿 Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
쮿 Bandwidth Control:
Support ingress and egress per port bandwidth control.

쮿 Chapter 1: Introduction
EN
쮿 Power saving:
The switch can detect inactive links and deactivate the power supply for
the corresponding ports
쮿 SNMP:
SNMP agent. In the device, SNMP agent is a client software which is operating over SNMP protocol used to receive the command from SNMP
manager (server site) and echo the corresponded data, i.e. MIB object.
Besides, SNMP agent will actively issue TRAP information when happened.
The device supports MIB II (RFC1213), Bridge MIB (RFC1493), Interface
Group MIB (RFC2863).
쮿 IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used
to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP multicast packets are running over the network.

2.4 Mounting and connecting up the LANCOM Switch
Installating the LANCOM Switch involves the following steps:
햲 Mounting – The device is designed for mounting in an available 19” unit
in a server cabinet. If necessary fix the rubber pads to the underside of the
device to prevent any scratching to other equipment.
Ensure that the device has sufficient ventilation to prevent damage
햳 LAN connection – Connect the network devices to the ports of the
from excessive heat build-up.
LANCOM Switch by means of a suitable twisted-pair cable (TP cable). The
connectors automatically detect the avalable data transfer speeds and the
pin assignment (autosensing).
햴 Supply power and switch on – Supply power to the device by means of
the IEC power cable.
햵 Ready for operation? – After a brief self-test, the power LED lights up
continuously. Green LAN-LINK LEDs show which LAN connectors are
being used for a connection.
12
Use only standard TP cables of category CAT 5e or better with a maximum length of 100 m to ensure the best possible transfer of data.
Cross-over cables can be used thanks to the auto-sensing function.
If optical connections are to be used, additional modules can be
purchased as accessories.
2.5 Software installation
The following section describes the installation of the Windows-compatible
system software LANtools, as supplied.
You may skip this section if you use your LANCOM Switch exclusively
with computers running operating systems other than Windows.

Switch
3.1 Configuration with WEBconfig
The configuration is done over a graphical user interfacevia a browser
(WEBconfig). Instructions for configuring the device with WEBconfig are available in the chapter "Web-based configuration".
There are two ways of starting the configuration by browser:
쮿 If you know the device's IP address, simply enter this into the address line
in the browser. The password for accessing the device is "admin".
EN
쮿 If you do not have the device's IP number, LANconfig can be used to
search for it. To start LANconfig click on Start 왘 Programs 왘 LANCOM
왘 LANconfig.
15
LANCOM GS-1224
쮿 Chapter 3: Configuring and monitoring the LANCOM Switch
EN
LANconfig automatically searches for all available devices in your network. Any available LANCOM devices will be displayed in the list, including the LANCOM Switch. Double-click on this entry to start the browser
automatically with the correct IP address.
What is the IP address of my LANCOM Switch?
The current IP address of the LANCOM Switch after being switched on depends on the network
constellation.
Networks with DHCP server – In its factory settings, the LANCOM Switch is set for auto DHCP
mode, meaning that it searches for a DHCP server to assign it an IP address, subnet mask and
gateway address. The assigned IP address can only be determined by using the appropriate
tools or via the DHCP server. If the DHCP server is a LANCOM device, the IP address of the LANCOM Switch can be read out from the DHCP table. If this is the case, the LANCOM Switch can
be accessed from any network computer that receives its IP address from the same subnetwork.
Network without a DHCP server – If no DHCP server is present in the network, the LANCOM
Switch waits about 5 minutes and then automatically adopts the address "172.23.56.250".
If this is the case, the LANCOM Switch can be accessed from any network computer with its IP
address set to the address range "172.23.56.x".
3.2 Back up and reload the configuration
With this function you can back up or reload you current configuration for
safety reasons. This backup can be uploaded into a new or defective device.

3.3 Monitoring the LANCOM Switch with LANmonitor
The current state of the device and all ports can be monitored using the LEDs
on the front panel. With LANmonitor the devices can be observed from any
workstation without being able to see the LEDs. Besides the status information provided by the LEDs the LANmonitor provides further important information on the ports.
3.3.1 Ethernet port status
LANmonitor displays the current status of all of the device's Ethernet ports.
This includes monitoring of the state as configured by the admin (config state)
and the actual state (link state) of the port. Each port is displayed with two
colored symbols in LANmonitor:
EN
쮿 The left icon shows the config state:
왏 Gray: The port is deactivated in the configuration
왏 Yellow: The port is activated in the configuration
쮿 The right-hand icon shows the link state:
왏 Gray: No active network device is connected to the port
왏 Green: A network device is connected to the port and active
