1.2 Management Options
Switch management options available in MS400870M Series are listed and described
below:
Local Console Management
Telnet Management
SNMP Management
WEB Management
Local Console Management
Local Console Management is done through the RS-232 DB-9 Console port located in the
back of the MS400870M Series Switch. Direct RS-232 cable connection between the PC
and the Managed switch is required for this type of management.
Telnet Management
Telnet runs over TCP/IP and allows you to establish a management session through the
network. Once the Managed switch is on the network with proper configurations, you can
use Telnet to login and monitor its status remotely.
SNMP Management
SNMP is also done over the network. Apart from standard MIB (Management Information
Bases), an additional private MIB is also provided for SNMP-based network management
system to compile and control.
Web Management
Web Management is done over the network and can be accessed via a standard web
browser, such as Microsoft Internet Explorer. Once the Managed switch is available on the
network, you can login and monitor the status of it through a web browser remotely or
locally. Local Console-type Web management, especially for the first time use of the
Managed Switch to set up the needed IP, can be done through one of the 10/100Base-TX 8-
pin RJ-45 ports located at the front panel of the Managed Switch. Direct RJ45 LAN cable
connection between a PC and the Managed Switch is required for Web Management.

10
1.3 Management Software
Following is a list of management software choices for MS400870M Series:
Managed switch CLI interface
SNMP-based Management Software
Web Browser Application
Console Program
The Managed Switch has a built-in, Command Line Interface called the CLI which you can
use to:
Configure the system
Monitor the status
Reset the system
You can use CLI as the only management system. However, other network management
option - SNMP -based management system is also available.
You can access the text-mode Console Program locally by connecting a VT100 terminal - or
a workstation running VT100 emulation software - to the Managed Switch RS-232 DB-9
Console port directly. Or, you can use Telnet to login and access the CLI through network
connection remotely.
SNMP Management System
Standard SNMP-based network management system is used to manage the Managed
Switch through the network remotely.
When you use a SNMP-based network management system, the Managed switch becomes
one of the managed devices (network elements) in that system. The Managed switch
management module contains an SNMP agent that will respond to the requests from the
SNMP-based network management system. These requests, which you can control, can
vary from getting system information to setting the device attribute values.
The Managed Switch‟s private MIB is provided for you to install in your SNMP-based
network management system.
Web Browser Application
You can manage the Managed Switch through a web browser, such as Internet Explorer or
Netscape, etc. (The default IP address of the Managed Switch port can be reached at
“http://192.168.0.1”.) For your convenience, you can use either this Web-based
Management Browser Application program or other network management option, for
example SNMP-based management system as your management system.

11
1.4 Management Preparations
After you have decided how to manage your Managed Switch, you are required to connect
cables properly, determine the Managed switch IP address and, in some cases, install MIB
shipped with your Managed Switch.
Connecting the Managed switch
It is very important that the proper cables with the correct pin arrangement are used when
connecting the Managed switch to another switches, hubs, workstations, etc.
1000Base-X / 100Base-FX SFP Port
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
data communications applications. It interfaces a network device mother board (for a
switch, router or similar device) to a fiber optic or unshielded twisted pair networking
cable. It is a popular industry format supported by several fiber optic component
vendors.
SFP transceivers are available with a variety of different transmitter and receiver
types, allowing users to select the appropriate transceiver for each link to provide the
required optical reach over the available optical fiber type. SFP transceivers are also
available with a "copper" cable interface, allowing a host device designed primarily for
optical fiber communications to also communicate over unshielded twisted pair
networking cable.
SFP slot for 3.3V mini GBIC module supports hot swappable SFP fiber transceiver.
Before connect the other switches, workstation or Media Converter, make sure both
side of the SFP transfer are with the same media type, for example: 1000Base-SX to
1000Base-SX, 1000Bas-LX to 1000Base-LX.And check the fiber-optic cable type
match the SFP transfer model. To connect to 1000Base-SX transceiver, use the
multi-mode fiber cable- with one side must be male duplex LC connector type. To
connect to 1000Base-LX transfer, use the single-mode fiber cable-with one side must
be male duplex LC connector type.
10/100/1000Base-T RJ-45 Auto-MDI/MDIX Port
24 x 10/100/1000Base-T RJ-45 Auto-MDI/MDIX ports are located at the front of the
Managed Switch. These RJ-45 ports allow user to connect their traditional copper-
based Ethernet/Fast Ethernet devices to the network. All these ports support auto-
negotiation and MDI/MDIX auto-crossover, i.e. either crossover or straight through
CAT-5 UTP or STP cable may be used.
RS-232 DB-9 Port
The RS-232 DB-9 port is located at the rear of the Managed Switch. This DB-9 port is
used for local, out-of-band management. Since this DB-9 port of the Managed switch
is DTE, a null modem is also required to connect the Managed Switch and the PC.

12
By connecting this DB-9 port, it allows you to configure & check the status of
Managed Switch even when the network is down.
IP Addresses
IP addresses have the format n.n.n.n, (The default factory setting is 192.168.0.1).
IP addresses are made up of two parts:
The first part (for example 192.168.n.n) refers to network address that identifies the
network in which the device resides. Network addresses are assigned by three
allocation organizations. Depending on your location, each allocation organization
assigns a globally unique network number to each network that wishes to connect to
the Internet.
The second part (for example n.n.0.1) identifies the device within the network.
Assigning unique device numbers is your responsibility. If you are unsure of the IP
addresses allocated to you, consult with the allocation organization where your IP
addresses were obtained.
Remember that none of the two devices on a network can have the same address. If you
connect to the outside network, you must change all the arbitrary IP addresses to comply
with those you have been allocated by the allocation organization. If you do not do this, your
outside communications will not be performed.
A subnet mask is a filtering system for IP addresses. It allows you to further subdivide your
network. You must use the proper subnet mask for proper operation of a network with
subnets defined.
MIB for Network Management Systems
Private MIB (Management Information Bases) is provided for managing the Managed switch
through the SNMP-based network management system. You must install the private MIB
into your SNMP-based network management system first.
The MIB file is shipped together with the Managed Switch. The file name extension is “.mib”
that allows SNMP-based compiler can read and compile.

13
2. Command Line Interface (CLI)
This chapter introduces you how to use your MS400870M Series CLI, specifically in:
Local Console
Telnet
Configuring the system
Resetting the system
The interface and options in Local Console and Telnet are the same. The major difference
is the type of connection and the port that is used to manage the Managed Switch.
2.1 Using the Local Console
Local Console is always done through the RS-232 DB-9 port and requires a direct
connection between the switch and a PC. This type of management is useful especially
when the network is down and the switch cannot be reached by any other means.
You also need the Local Console Management to setup the Switch network configuration for
the first time. You can setup the IP address and change the default configuration to desired
settings to enable Telnet or SNMP services.
Follow these steps to begin a management session using Local Console Management:
Step 1. Attach the serial cable the RS-232 DB-9 port located at the back of the Switch
with a null modem.
Step 2. Attach the other end to the serial port of a PC or workstation.
Step 3. Run a terminal emulation program using the following settings:
Emulation VT-100/ANSI compatible
BPS 9600
Data bits 8
Parity None
Stop bits 1
Flow Control None
Enable Terminal keys
Step 4. Press Enter to access the CLI (Command Line Interface) mode.

14
2.2 Remote Console Management - Telnet
You can manage the Managed Switch via Telnet session. However, you must first assign a
unique IP address to the Switch before doing so. Use the Local Console to login the
Managed Switch and assign the IP address for the first time.
Follow these steps to manage the Managed Switch through Telnet session:
Step 1. Use Local Console to assign an IP address of the Managed Switch,
IP address
Subnet Mask
Default gateway IP address, if required
Step 2. Run Telnet.
Step 3. Log into the Switch CLI mode.
Limitations: When using Telnet, keep the following in mind:
Only two active Telnet sessions can access the Managed Switch at the same time.

15
2.3 Navigating CLI
The Command Line Interface (CLI) of MS400870M Series is divided into three different
modes. After you enter the authorized username and password, you start from the User
mode. The commands available depend on which mode you are currently in. Enter a
question mark (?) at the system prompt to obtain a list of commands available for each
command mode.
In CLI management, the User mode only provides users basic functions to operate the
Managed Switch. If you would like to configure advanced features of the Managed Switch,
such as, VLAN, QoS, Rate limit control, you must enter the Enable or Config mode. The
CLI management of this Managed Switch is structured in a hierarchical manner which
means that when you want to enter Enable mode you must start from the User mode and
enter the required command and password and when you want to enter Config mode you
must enter the required command in Enable mode. The following table provides an overview
of this Managed Switch.
