1. Introduction

1

In today’s society, the ability to communicate quickly and share important data is
essential to our lifestyle. Computer networks have proven to be one of the fastest
methods of communication.

The MIL-SM801XX series are compact desktop size switches that are ideal
solutions for small, medium and enterprise networks. The switch provides wire­speed switching with high-performance, and low-cost connections. Using the store­and-forward switching method, this switch can auto-learn and store up to 8K worth
of MAC addresses.

Figure 1-1. The MIL-SM801XX

The MIL-SM801xx switch provides eight-switched auto-sensing 10/100 Mbps RJ-45
Ethernet ports plus one 100Base-FX fiber port. The switch will automatically detect
the speed of the device that you plug into, allowing you to use both 10 and
100Mbps devices. The 10Mbps bandwidth will accommodate 10Mbps workgroup
hubs while simultaneously providing the 100Mbps bandwidth needed to
accommodate multimedia applications. In addition, each RJ-45 port supports Auto
MDI/MDIX for easy installation.

The MIL-SM801XX switch provides one 100Base-FX fiber port. There are 4 types
of fiber connectors available on the switch. These fiber connectors are SC, ST, MT­RJ, VF-45 (multi-mode) and SC (single-mode). The fiber port can be used to
connect to a remote site up to 2 kilometers (multi-mode) or 15~60 kilometers (SC
single- mode).

The MIL-SM801XX includes built in Web-based Management. You can easily
configure and monitor the switch through your web browser. You can also use our
text base console program through Telnet, Serial Console, or any SNMP
management system.

Compare the contents of your MIL-SM801XX package with the standard checklist
above. If any item is missing or damaged, please contact your local dealer for
service.

Ethernet Switching Technology

Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with Carrier Sense Multiple
Access with Collision Detection protocol, and greatly reduced unnecessary
transmissions.

Switches have revolutionized the network world in three major ways. First, by using
a switch you can have two-way, simultaneous transmissions over the same port (full
duplex), essentially doubling the bandwidth. Second, by reducing the collision
domain to a single switched-port “Carrier Sensing” is eliminated. Third, using store­and-forward switching, unnecessary transmissions can be eliminated to avoid
congestion.

Auto-negotiation regulates the speed and duplex of each port, based on the
capability of both devices. Flow-control allows transmission from a 100Mbps node
to a 10Mbps node without loss of data. You may need to disable auto-negotiation
and flow control for some networking operations involving legacy equipment.
Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a
port.

Management Methods

4

The MIL-SM801XX series supports the following management methods:

n Console and Telnet Management
n Web-based Management
n SNMP Network Management

Console and Telnet Management

Console Management is done through the serial Console Port. This method
requires a direct connection between a PC and the MIL-SM801XX. Telnet
management is done over the network. Once the MIL-S801XX has an assigned IP
address and is on the network, you can use Telnet to login and make configuration
changes.

Web-based Management

The switch provides an embedded HTML web site residing in flash memory. It offers
advanced management features and allows users to manage the MIL-SM801XX
from anywhere on the network through a standard browser such as Microsoft
Internet Explorer or Netscape Navigator. For more information, see chapter 6.

SNMP Network Management

SNMP (Simple Network Management Protocol) provides a way to monitor and
control network devices, and to manage configurations, statistic collection,
performance, and security.

2. Hardware Description

This section explains how to configure console management using the console
management program.

Console management involves the administration of the switch via a direct
connection to the RS-232 console port, which has a female DB-9 connector. From
the main menu of the console program, user has access to manage the functions of
the switch.

Connecting a Terminal or PC to the Console Port

Figure 3-1. Connecting the MIL-SM801XX to a terminal via RS-232 cable

Use the supplied RS-232 cable to connect a terminal or PC to the console port. The
terminal or PC to be connected must support the terminal emulation program.

After connecting the switch via the RS-232 cable, run a terminal emulation
program or Hyper Terminal to match the following default characteristics of the
console port:

Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Control flow: None

The settings of communication
parameters

Note: Console program is case sensitive.

10

After you have finished setting parameters, press the “Enter” Key and the Main
Menu of console management appears.

Figure 3-3. The Main Menu of Console Management

Assigning an IP Address to the switch

Once you have logged into the MIL-SM801XX, you need to assign an IP address to
the switch’s Ethernet interface so that you can connect to the switch using a Web
Browser.

1. From the Main Menu of the console, select Item 1 by typing in “1” after the

prompt and press Enter. You must select the appropriate Boot Method ---
Flash, BOOTP, or DHCP (For more information, see Web-based Management
– Agent Config ).

2. There are three command options to change the IP Address (the initial Default

IP address is 192.168.1.77). For example, if you wanted to change the IP
address to 199.86.12.40, you could type one of the following at the MIL
prompt:

MIL> ip-address 199.86.12.40
MIL> 2 199.86.12.40
MIL> ip 199.86.12.40

Note: After typing in the command press Enter twice.

3. You will now find that the default IP address has been changed to IP address

192.168.12.40. Reboot by typing “reboot” or “H”.

4. By similar methods, you can configure Subnet Mask (default subnet Mask is

255.255.255.0), Broadcast (default Broadcast is 255.255.255.255), and
Gateway (default Gateway is 192.168.1.6). The gateway address is the router
that can forward packets to the other IP networks.

Figure 3-4. Changing IP address by typing in “ ip-address 199.86.12.40 ” after the prompt .

11

Figure 4-5. Execute reboot

12

Figure 3-6. After pressing Enter twice, you will find the old IP address has changed into new
IP address.

Note: After any setting changes, reboot. Use the ping command for verification.

Secured IP

13

Secured IP can guard against unauthorized users accessing the switch
management. Network security for IP access allows only one IP address or up to 3
IP addresses to access the web based management server and telnet server.

The Default Secured IP is 0.0.0.0 for all three secured IP, which means that no
network security on IP was set from original factory setting. Now, if you want to set
Secured IP, for example, you can type in “securedip 1 199.86.12.46” after the
prompt press Enter twice. The first Secured IP has been registered. Only the end
station with IP 192.168.1.27 has access to the network management.

Figure 3-7. Type in “ securedip 1 199.86.12.46” after the prompt in order to set the first
secured IP.

Figure 3-8. After pressing Enter twice, the first secured IP address is set to 199.86.12.46.

Resetting Factory Defaults

You can reset the switch back to factory default settings by using the loaddefault

command. Simply type L 2 at the MIL>_ prompt and press enter.

Note: If you do not type L 2, and only type L, the following option appears:

Usage: loaddefault (0:1:2).

The only correct option is L 2 for the MIL-SM801XX.

VLANS

21

A LAN was originally defined as a network of computers located within the same
area.. Today, LANs are defined as a single broadcast domain. This means that if a
user broadcasts information on his/her LAN, every user on the LAN will receive the
broadcast. A VLAN (Virtual LAN) is a group of ports designated by the switch as
belonging to the same broadcast domain. This feature allows workgroups to be
defined on the basis of their logical location instead of their physical location.

VLANs can be used to strengthen security between the departments as well as
isolating broadcast traffic to increase net bandwidth.

Figure 5-5. The example of VLAN setting on VLAN Page

Each port can be configured to belong to one or more of the nine VLANs by clicking
on the desired group(s). By default, all ports are a member of one group. A port
can be a member of more than one group.

Trunking

22

Trunking allows you to create additional bandwidth by aggregating several ports
into one single group.

Figure 5-6. The Trunking Page

From the Trunking page you can click the drop-down menu and select your desired
trunk group. You have a choice between a 2-port trunk (ports 1&2) or 4-port trunk
(ports 1, 2, 3, & 4).

Remember to click Apply after making your selection.

Note: Make sure Trunking ports are in the same VLAN group.

Agent Config

23

After clicking the Agent Configuration page, the screen displays the MIL­SM801XX’s current configuration. Refer to the following Agent Configuration page
for your own settings.

Figure 5-7. The Agent Config Page

Boot Methods

24

There are three modes that you can boot your switch in --­FLASH Boot – Boots from a memory chip that software images can be stored,
booted, and rewritten as necessary. Flash memory resides in a chip and holds its
content without power.

BootP - Boots your system from a BootP (Bootstrap Protocol) server. BootP is a
TCP/IP protocol used by a diskless workstation or network computer to obtain its IP
address and other network information such as server address and default
gateway.

DHCP Boot – Boots your system from a DHCP (Dynamic Host Configuration
Protocol) server. DHCP servers can automatically assign IP addresses to client
stations logging onto a TCP/IP network.

The following are the initial factory values. You can change the information by

7. Troubleshooting

26

This section is intended to help you resolve the most common problems on the MIL­SM801XX series.

Incorrect connections

n Faulty or loose cables

Look for loose or obviously faulty connections. Make sure the connections are
snug. If that does not correct the problem, try a different cable.

n Non-standard cables

Non-standard or incorrectly pinned cables may cause anything from network
collisions to no network connectivity at all. A category 5 cable tester is
recommended during your network installation.

n Improper Network Topologies

It is important to make sure that you have a valid network topology. Common
topology faults include excessive cable length and too many repeaters (hubs)
between end nodes. In addition, you should make sure that your network topology
contains no data path loops. Between any two-end nodes, there should be only one
active cabling path at any time. Data path loops will cause broadcast storms that
will severely impact your network performance.

Diagnosing LED Indicators

You can diagnose common problems by monitoring the LED indicators on the front
panel of the switch. If you are having network connection issues the first place to
check is the switches LED link lights. If you do not have a link light, you may have
an incorrect cable type.

If the power LED does not light up when the power cord is plugged in, you may
have a problem with power outlet, or power cord.

n Cabling

RJ-45 ports - Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable
for the RJ-45 connections. Use 100ohms Category 3, 4 or 5 cable for 10Mbps
connections or 100ohms Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed 100 meters (328
feet).

100Base-FX fiber port - Fiber multi-mode connector type must use 50/125 or

62.5/125µ multi-mode fiber cable. You can connect two devices up to 2-kilometers.
With single-mode fiber use 9/125µ fiber cable for multi-mode as well. You can
connect two devices from 15 to ~60- kilometers in full duplex operation.
