LANCOM switches are the foundation for a reliable infrastructure. These switches deliver multiple intelligent features for improving the availability of your critical business applications, protecting your sensitive information, and optimizing your network bandwidth to deliver information and applications more effectively. Easy to set up and use, they provide the ideal combination of economic efficiency and technical capabilities from entry level to enterprise level networks. All models offer enhanced security and management functions. In addition, they have networking features to support common applications of data, voice, security and wireless networking.

1.2 Switch Architecture

The switches performs a wire-speed, non-blocking switching fabric. This allows wire-speed transport of multiple packets at low latency on all ports simultaneously. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

The switches use store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

1.3 Network Management

The switch can be managed over the network with a web browser or CLI (Command Line Interface) via SSH or Telnet. Particular devices can be configured via the web-based interface only. These switches include a built-in network management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols.

For out-band management particular devices offer a RJ45 console port connector on the front panel, other devices offer a serial port on the back or front.

For a detailed description of the management features, refer to the user manual.

2 Network Planning

2.1 Introduction to Switching

A switch allows simultaneous transmission of multiple packets, it can partition a network more efficiently than bridges or routers. Therefore, the switch has been recognized as one of the most important device for today's networking technology.

When performance bottlenecks are caused by congestion at the network access point such as file server, the device can be connected directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch can subdivide the network into smaller and better manageable segments and recombine them to larger networks, thus removing the limitations by the maximum hop count.

A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly increase bandwidth while using conventional cabling and network cards.

2.2 Application Examples

The switches implement Gigabit Ethernet TP ports with auto MDIX and slots for removable SFP modules which support comprehensive types of fiber connection, such as LC and BiDi-LC modules. It is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below.

Among others, the switches are suitable for the following applications:

Remote site application is used in Enterprise or SMB
Peer-to-peer application is used in two remote offices
Office network

Position the switch near the devices you want to link and near a power outlet.
Be able to maintain the temperature of the switch within the limits listed in the Hardware Quick Reference Guide.
Have the switch accessible for installing, cabling, and maintaining the devices.
Allow the status LEDs to be clearly visible.

Make sure the twisted-pair Ethernet cable is always routed away from power lines, radios, transmitters or any other electrical interference.

Make sure that the switch is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz.

3.2 Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that the available cables are suitable for 100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network:

Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cable with RJ-45 connectors; Category 5 or Category 5e with maximum length of 100 meters is recommend for 100BASE-TX, and Category 5e or 6 with maximum length of 100 meters is recommend for 1000BASE-T
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires and data – based network wiring
Safe connections with no damaged cables, connectors or shields

(TP cable). The connectors automatically detect the available data transfer speeds and the pin assignment (autosensing).

Use only standard TP cables of category CAT 5 or better with a maximum length of 100 m to ensure the best possible data transfer. Cross-over cables can be used thanks to the auto-sensing function.

If optical connections are used, additional modules are necessary which can be purchased as accessories.

③ Supply power – Supply power to the device by means of the IEC power cable and/or an external power supply unit (model dependent).
④ Ready for operation? – After a brief self-test, the power or system LED lights up continuously. Green Link/Act LEDs show which LAN connectors are used for a connection.

4 Configuring and Monitoring the LANCOM Switch

4.1 Configuration options

There are two different options to configure the device:

By means of a graphical user interface or via browser (WEBconfig). This option is only available if you have network access to the device's IP address from your computer. The computer requires an operating system that supports TCP/IP (e.g. Windows, Linux, BSD Unix, Apple Mac OS) and also access to the LAN and a webbrowser.
Text-orientated configuration via console (Command Line Interface – CLI): This method of configuration, which requires a program such as SSH, Telnet, Hyperterminal, or similar, can be conducted over a network connection or with a direct connection via serial interface (RS-232).

When working with Windows, you can use the LANtools to detect and monitor LANCOM switches.

LANconfig 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.

With LANmonitor you can use a Windows computer to monitor all of your LANCOM devices. This program displays all important status information.

4.1.1 Starting WEBconfig

There are two ways of starting the configuration by browser:

If you know the device's IP address, simply enter this into the address line of the browser. The factory settings for accessing the device are: User name "admin", password "admin".
If you do not have the device's IP address, LANconfig can be used to search for it. To start LANconfig click on Start / Programs / LANCOM / LANconfig. LANconfig automatically searches for all available devices in your network. Any available LANCOM routers or access points displayed in the list, including LANCOM switches. 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 (e.g. LANconfig) or via 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 DHCP server.
Network without a DHCP server – If no DHCP server is present in the network, the LANCOM switch adopts an address which, depending on the model, may be "172.23.56.250" or "172.23.56.251". If this is the case,

Chapter 4: Configuring and Monitoring the LANCOM Switch

the LANCOM switch can be accessed from any network computer with its IP address set to the address range "172.23.56.x".

4.1.2 Starting the Command Line Interface over the Network

If you know the device's IP address (see section above) and the LANCOM switch is accessible from your computer via the network, you can use the command line interface via the network.

① To do this, start a console such as SSH or Telnet and enter the device's IP address as the target.
② Log on with user name and password (default: admin, password: admin).

4.1.3 Starting the Command Line Interface over the Serial Connection

If you do not know the IP address of the device, you can use the command line interface via a serial connection.

① Use the serial configuration cable to connect the LANCOM switch to the configuration computer (see "Mounting and connecting the LANCOM Switch").
② Start a terminal program on the configuration computer, such as PuTTY. Use the following parameters for the connection:

Baud rate: 115200
Stop bits: 1
Data bits: 8
Parity: N
Flow control: none

③ Log on with user name and password (default: admin, password: admin).

4.2 Monitoring the LANCOM Switch with LANmonitor

The current status of the device and all its 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 switch. Besides the status information provided by the LEDs, LANmonitor provides further important information on the ports.

4.2.1 Ethernet Port Status

LANmonitor displays the current status of all of the device's Ethernet ports. This includes monitoring the status as configured by the admin (config state) and the actual port status (link state). Each port is displayed with two colored symbols in LANmonitor:

The left icon shows the config status:

Gray: The port is deactivated in the configuration
Yellow: The port is activated in the configuration

The right-hand icon shows the link status:

Gray: No active network device is connected to the port
Green: A network device is connected to the port and active

Apart from the status, LANmonitor displays the VLAN ID for each port and the detected data rate at active ports connected to active network devices.
