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 connection, or through Ethernet port using Telnet or WEBconfig. Additionally, the
switches can be managed via SSH (Secure Shell) or WEBconfig with SSLencryption. 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.
EN
Additionally, the switches support TACACS+, a protocol for authentication,
authorization and accounting (AAA). It thus provides access to the network for
certain authorized users only, it regulates the rights of those users, and it is a
logging mechanism to keep track of user actions.
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.
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

쮿 Chapter 1: Introduction
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 256 active
EN
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 Port Security:
Support allowed, denied forwarding and port security with MAC address.
쮿 SNMP/RMON:
SNMP agent and RMON MIB. 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.
RMON is the abbreviation of Remote Network Monitoring and is a branch
of the SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON
MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643),
Ethernet MIB (RFC 1643) and so on.
쮿 TACACS+
Tacacs+ (Terminal Access Controller Access-Control System) is a protocol
for authentication, authorization and accounting (AAA). It thus provides
access to the network for certain authorized users only, it regulates the
rights of those users, and it is a logging mechanism to keep track of user
actions. TACACS+ is an alternative to other AAA protocols such as
RADIUS.
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

Instructions for configuring the device with CLI are available in the chapter "Command line interface".
3.1.1 Starting WEBconfig
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".

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 "172.23.56.250".
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".

3.1.2 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.
쐇 Log on with user name and password (default: admin, admin).
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.
EN
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:
왏 Baud rate: 115200

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.
EN
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
쐇 Working configuration:
saved as the start 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.
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”.
쐏 Default configuration
24
If the start configuration is defective and the the device is not available via network, you use the serial configuration interface and the
Command Line Interface to reload a functional start configuration.
LANCOM ES-2126+ and LANCOM ES-2126P+
쮿 Chapter 3: Configuring and monitoring the LANCOM switch
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.
EN
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 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.
EN
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:
