쮿 Chapter 1: Introduction
1Introduction
The LANCOM switch models LANCOM ES-2126+ and LANCOM ES-2126P are
managed layer-2 switches with 24 Fast Ethernet ports (for twisted pair cable
– TP) and two Gigabit dual media ports with TP/SFP, which meets the IEEE
802.3/u/x/z Gigabit, Fast Ethernet and Ethernet specifications
The switch can be managed through RS-232 serial port via directly connec-
tion, or through Ethernet port using Telnet or Web-based management unit,
associated with SNMP agent. With the SNMP agent, the network administrator can logon the switch to monitor, configure and control each port’s activity
in a friendly way.
The overall network management is enhanced and the network efficiency is
also improved to accommodate high bandwidth applications. 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/RMON and IGMP Snooping capability via the intelligent software.
It is suitable for both metro-LAN and office application.
This LANCOM ES-2126P switch also complies with IEEE 802.3af, its advanced
auto-sensing algorithm enables providing power devices (PD) discovery, classification, current limit, and other necessary functions. It also supports high
safety with short circuit protection and power-out auto-detection to PD.
10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE 802.3/u/
x/z Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver is a
Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000BaseSX/LX standards.
1000Mbps 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.

3.1 Configuration options
There are two different methods of configuring the device.
EN
3.1.1 Starting WEBconfig
쮿 By means of a graphical user interface or via a browser (WEBconfig). This
option is only available if you have network access to the device's IP
address from your computer.
Instructions for configuring the device with WEBconfig are available in the
chapter "Web-based configuration".
쮿 Text-orientated configuration via a console (Command Line Interface –
CLI): This method of configuration, which requires a program such as Telnet, Hyperterminal, or similar, can be conducted over a network connection or with a direct connection via serial interface (RS-232).
Instructions for configuring the device with CLI are available in the chapter "Command line interface".
20
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 factory settings for accessing the device are: User
name "admin", password "admin".
LANCOM ES-2126+ and LANCOM ES-2126P

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 DHCP server.
Network without a DHCP server – If no DHCP server is present in the network, the LANCOM
switch automatically adopts the address "172.23.56.252" (LANCOM ES-2126+) or
"172.23.56.251" (LANCOM ES-2126P). 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".
22
3.1.2 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, the you can use the
command line interface via the network.
쐃 To do this, start a console such as Telnet and enter the device's IP address
as the target.
LANCOM ES-2126+ and LANCOM ES-2126P
쮿 Chapter 3: Configuring and monitoring the LANCOM switch
쐇 Log on with user name and password (default: admin, admin).
EN
3.1.3 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.
쐃 Use the serial configuration cable to connect the LANCOM switch to the
configuration computer (→ "Mounting and connecting up the LANCOM
Switch').
쐇 Start a terminal program on the configuration computer, such as Hyper-
terminal under Windows. Use the following parameters for the connection:

3.2 Which configuration does the device use?
The switch supports four different configurations: The start configuration, the
current working configuration, the user configuration and the default configuration.
쐃 Start configuration
At the system start, the device takes the parameters from the start configuration and copies these to the working configuration. On shipping, the
start configuration is the same as the default configuration.
To change the start configuration, the altered parameters have to be
saved as the start configuration.
쐇 Working configuration:
This is the currently active configuration in the device. It can be changed
at any time. All changes to the configuration are saved here. Each time
you make changes and press <Apply>, the changes are stored to the working configuration.
The changes to the working configuration are not automatically
adopted for the start configuration. They have to be saved specifically
as the start or user configuration. If you do not save the changes to
your working configuration, they will be lost and the previous start
configuration will be active when you start the system the next time.
24
쐋 User configuration:
This configuration exists for specific requirements or for making backups.
You can save any state of the working configuration as a user configuration and restore this state later or with the function “Restore user configuration”.

쮿 Chapter 3: Configuring and monitoring the LANCOM switch
If the start configuration is defective and the the device is not avai-
lable via network, you use the serial configuration interface and the
Command Line Interface to reload a functional start configuration.
쐏 Default configuration
This is the default configuration and it cannot be altered. The web user
interface has the following options to restore the switch to its default
setting.
왏 With the function "restore default configuration included default IP
address" you can reset the switch to the factory default settings
(including the administrator´s password and the auto DHCP setting).
왏 With the function “restore default configuration without changing
current IP address” you can reset the switch to the factory default settings, but without changing the IP address. You can access the switch
at its last IP address.
왏 With the serial configuration interface you can reset the switch to the
factory default setting, without knowing the current administrator´s
password. To do this you have to set up a serial connection to the
device as described in → ’Start Command Line Interface via serial
connection’. In the terminal program, before you enter the username
press CTRL+Z, enter “RESET” as the username and the MAC address
(without blank characters) as the password.

This action starts the reset process and all settings will be reset to the
factory default state, including the administrator´s password and the
auto DHCP setting.
3.3 Save/Restore
The switch supports three copies of configuration, including the default configuration, working configuration and user configuration for your configuration management. All of them are listed and described below respectively.
쮿 Default Configuration:
This is ex-factory setting and cannot be altered. In Web UI, two restore
default functions are offered for the user to restore to the default setting
of the switch. One is the function of "Restore Default Configuration including default IP address", the IP address will restore to default
"192.168.1.1" as you use it. The other is the function of "Restore Default

Configuration without changing current IP address", the IP address will
keep the same one that you had saved before by performing this function.
쮿 Working Configuration:

time. The configurations you are using are saved into this configuration
file. This is updated each time as you press <Apply> button.
쮿 User Configuration:

It is the configuration file for the specified or backup purposes and can be
updated while having confirmed the configuration. You can retrieve it by
performing Restore User Configuration.

쮿 Restore default configuration (includes default IP address)
Here you can reset the switch to its factory settings. The default configuration replaces the start configuration. The device is reset to Auto DHCP
and it retrieves its IP address from a DHCP server in the network. If no
DHCP server is available, the device takes the IP address “172.23.56.252”
(LANCOM ES-2126+) or “172.23.56.251” (LANCOM ES-2126P).
쮿 Restore default configuration (excludes current IP address)

address as set up by the user is not changed and will NOT be restored to
the default value.
쮿 Restore user configuration
Restore User Configuration function retrieves the previous confirmed working configuration from the flash memory to update the start configuration. After restoring the configuration, the system’s start configuration is
updated and activated after rebooting.
