Introduction
Overview
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 data, 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 capabilites from entry level to enter-
prise 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.
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.

Network management
LANCOM Systems offers three types of switches: unmanaged switches,
websmart switches, and managed switches.
AUnmanaged switches are not configurable.
AWebsmart switches are configurable only by their web-based GUI.
Additionally, these switches offer an integrated network management
agent, which allows managing via SNMP or RMON (Groups 1, 2, 3, 9).
AManaged switches support configuration via LANCOM Management
Cloud (LMC), a web-based GUI, or CLI (Command Line Interface via SSH
or Telnet). For outband management, these switches either provide a
front-sided RJ45 console port, or a serial port at the front- or backside
of the device. This port can be used for connecting a null-modem cable
to a PC for configuration and monitoring purposes.
4A LANCOM switch automatically contacts the LMC for 24 hours
after startup (boot / reset) to successfully terminate the coupling.
This enables zero-touch deployment for operation with the LMC.

Configuration options for websmart and managed
switches
There are three different options to configure the device:
AVia a graphical user interface in a browser (WEBconfig):
This configuraton option (for websmart- and managed switches) is only
available if you have network access to the device’s IP address from
your computer.
AVia a graphical user interface in a browser (LANCOM Management
Cloud – LMC):
This configuration option (only for managed switches) is only available
if you have network access and both your device for configuration and
the switch have a connection to the LANCOM Management Cloud.
AConfiguration via console (Command Line Interface – CLI):
This method of configuration (only for managed switches), 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 / RJ45).

12
LANCOM Installation Guide – Configuration

WEBconfig
There are two ways of starting the configuration by browser:
AIf 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:
ABefore LCOS SX 4.00: User name: admin, password: admin
AAs from LCOS SX 4.00: User name: admin, password: <empty>
AIf you do not have the device’s IP address, LANconfig can be used to
search for it. LANconfig automatically searches for all available devices
in your network. Any available LANCOM routers or access points will be
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.
Aa 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 appro-
priate 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.
ANetwork without a DHCP server – If no DHCP server is present in the
network, the LANCOM switch 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.

LANCOM Management Cloud
In order to configure a LANCOM switch via the LANCOM Management
Cloud (LMC), it must first be integrated into the LMC.
Integrating the switch into the LMC requires the switch to be connected to
the Internet and able to reach cloud.lancom.de.
There are two different methods of integrating a LANCOM device into the
LANCOM Management Cloud:
AIntegration into the LANCOM Management Cloud by serial number and
Cloud PIN
AIntegration into the LANCOM Management Cloud by activation code
Integration into the LMC by serial number and Cloud PIN
If you have purchased a LANCOM switch that was shipped with LCOS SX
(formerly LANCOM Switch OS) 3.30 or later – i.e. it is already “Cloud-ready”
– all you have to do is simply add the device to a project in the LANCOM
Management Cloud (Public).
You will need the serial number of the switch and the associated Cloud
PIN. You can find the serial number on the bottom of the switch or in
LANconfig or WEBconfig. The Cloud PIN can be found on the Cloud-ready
flyer, supplied with the device.

14
LANCOM Installation Guide – Configuration
EN
In the LANCOM Management Cloud, open the Devices view and click Add
new device.
In the next window, enter the serial number and Cloud PIN of the switch.
Then confirm with the button Add new device.
A LANCOM switch automatically contacts the LMC for 24 hours after
startup (boot / reset) to successfully conclude the pairing. After these 24
hours you can restart this period by a reset or use the following method
with activation code.

A Cloud PIN for integration into the LANCOM Management Cloud
(Public) is available for all switches delivered with LCOS SX (formerly
LANCOM Switch OS) 3.30 or later. If you have a device without a
Cloud PIN, you can also use an activation code to register the de-
vice.

Integration into the LMC by LMC Rollout Assistant
The Rollout Assistant is a web application. It uses a device equipped with a
camera and Internet access, such as a smartphone, tablet or notebook, to
read the serial number and PIN. It offers an extremely easy way to connect
the device to the LMC.
To start the Rollout Assistant, just enter the URL cloud.lancom.de/rollout
into a browser. The Rollout Assistant opens with this login screen:
You select the desired language and login to the LMC using your
credentials.
On the next page, you select the project that new devices are added to.
Do this by tapping the green button and scanning the serial number. The
Rollout Assistant may request access to the camera on the device to do

this. You scan the serial number either on the underside of the device or
alternatively from the barcode on the packaging box. Otherwise, you can
enter the serial number manually.
Next, scan the cloud PIN from the information sheet enclosed with the
device. Here, too, you have the option of entering the PIN manually.
Now you can select one of the locations available in the project, or
optionally use No location to leave this item open. Bear in mind that the
location is an important setting for the configuration by SDN (Software-
defined Networking).
In the next step, you assign various properties to the device. You give the
device a name, enter an address, and take a photo of the installation. The
address can be determined with the GPS information from your device.
In the final step, the information is displayed once again for checking. If
you find any errors, simply go back and correct the corresponding entry.
Click or tap add device to pair the device with the LMC. You will immedi-
ately see it in your project and can make other settings if necessary. As
soon as you connect the device and it connects with the LMC, it is provi-
sioned with an initial operating configuration based on the SDN settings,
and the status changes to “online”.
