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 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 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.
1.1 Key Features in the Device
쮿QoS:
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.
쮿Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol)
standards.
쮿VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 24 active
VLANs and VLAN ID 1~4094.
쮿Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
쮿Bandwidth Control:
Support ingress and egress per port bandwidth control.

EN
쮿Power saving:
The switch can detect inactive links and deactivate the power supply for
the corresponding ports
쮿SNMP:
SNMP agent. In the device, SNMP agent is a client software which is ope-
rating 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 happe-
ned.
The device supports MIB II (RFC1213), Bridge MIB (RFC1493), Interface
Group MIB (RFC2863).
쮿IGMP 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 mul-
ticast packets are running over the network.

2.3.2 Connectors on rear of the LANCOM GS-1224
The following connectors are located on the rear of the device.
쐃Connector for the power supply cable.
2.4 Mounting and connecting up the LANCOM Switch
Installating the LANCOM Switch involves the following steps:
햲Mounting – 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
from excessive heat build-up.
햳LAN connection – Connect the network devices to the ports of the
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).
Use only standard TP cables of category CAT 5e or better with a maxi-
mum 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.
햴Supply power and switch on – Supply power to the device by means of
the IEC power cable.
햵Ready 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.

2.5.2 Which software should I install?
쮿LANconfig is the Windows configuration program for all LANCOM
devices. LANconfig searches for all LANCOM devices in your network.
You can use this to start the Web-based configuration of a LANCOM
Switch.
쮿With LANmonitor you can use a Windows computer to monitor all of
your LANCOM devices. This program displays all important status infor-
mation for a LANCOM Switch, such as link status or port PoE state.
쮿With Documentation you copy the documentation files onto your PC.
Select the appropriate software options and confirm your choice with Next.
The software is installed automatically.

3 Configuring and monitoring the LANCOM
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 avai-
lable in the chapter "Web-based configuration".
There are two ways of starting the configuration by browser:
쮿If 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".
쮿If you do not have the device's IP number, LANconfig can be used to
search for it. To start LANconfig click on Start 왘Programs 왘LANCOM
왘LANconfig.

LANconfig automatically searches for all available devices in your net-
work. Any available LANCOM devices will be displayed in the list, inclu-
ding the LANCOM Switch. Double-click on this entry to start the browser
automatically with the correct IP address.
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.
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 LAN-
COM 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".

3.3 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 informa-
tion provided by the LEDs the LANmonitor provides further important infor-
mation 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:
쮿The left icon shows the config state:
왏Gray: The port is deactivated in the configuration
왏Yellow: The port is activated in the configuration
쮿The right-hand icon shows the link state:
왏Gray: No active network device is connected to the port
왏Green: A network device is connected to the port and active

4 Operation of Web-based Management
This chapter instructs you how to configure and manage the LANCOM GS-
1224 Switch through the web user interface (WEBconfig). With this facility,
you can easily access and monitor through any one port of the switch all the
status of the switch.
The default values of the managed switch are listed in the table below:
Web Smart Switch supports a simplified user management function which
allows only one administrator to configure the switch at one time. Fill in the
IP address in the address row in a browser to start WEBconfig. The default
password is “admin”.
4.1 Web Management Home Overview
After login, System Information will be displayed as the following screenshot
