Remote Console Management  
Configuring the Switch  
You can manage the Switch remotely by having a remote host establish a  
Telnet connection to the switch via an Ethernet or modem link.  
Overview  
The Switch features a menu-driven console interface for switch configura-  
tion. The Switch can be configured locally through the console port using ter-  
minal emulation software, such as Hyperterminal, or remotely via a Telnet  
connection.  
To use this management method:  
•
•
The host must run a SLIP protocol if a modem is used  
The Switch must have an IP address. The default IP address is  
192.168.1.254.  
Web-Based Configuration and Management  
•
Remote Telnet Login must be enabled on the Switch.  
This User Guide provides instructions on how to configure and manage the  
Switch using the console interface. If you wish to manage the switch through  
a web connection, you can do so by connecting to the Switch’s IP Address  
using your web browser.  
The Remote Console Management interface is identical in appearance and  
functionality to the Local Console Management interface. If you are using  
Microsoft’s Telnet, the terminal setting should be set to VT100/ANSI.  
SNMP Management  
Although the web-based management menu will differ in appearance from  
the console-based management menu, you will still have access to all the  
same configuration and management features.  
You can manage the Switch across a LAN using an SNMP Network  
Management Station with a graphical user interface. This management  
method allows you to monitor statistical counters and set switch parameters  
from the remote Network Management Station.

Overview  
• Link down  
This section describes the Switch’s Simple Network Management  
Protocol (SNMP) and Remote Monitoring (RMON) capabilities.  
• Authentication failure  
• Rising alarm  
• Falling alarm  
• Topology change  
RMON is an abbreviation for the Remote Monitoring MIB (Management  
Information Base). RMON is a system defined by the Internet Engineering  
Task Force (IETF) document RFC 1757, which defines how networks can be  
monitored remotely. RMONs typically consist of two components: an RMON  
probe and a management workstation:  
MIB-2 defines a set of manageable objects in various layers of the TCP/IP  
protocol suites. MIB-2 covers all manageable objects from layer 1 to layer 4  
and, as a result, is the major SNMP MIB supported by all vendors in the net-  
working industry. The Switch supports a complete implementation of SNMP  
Agent and MIB-2.  
• The RMON probe is an intelligent device or software agent that continually  
collects statistics about a LAN segment or VLAN. The RMON probe trans-  
fers the collected data to a management workstation on request or when a  
pre-defined threshold is reached.  
RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)  
The Switch provides hardware-based RMON counters in the switch chipset.  
The switch manager CPU polls these counters periodically to collect the sta-  
tistics in a format that complies with the RMON MIB definition.  
• The management workstation collects the statistics that the RMON probe  
gathers The workstation can reside on the same network as the probe, or it  
can have an in-band or out-of-band connection to the probe.  
RMON GROUPS SUPPORTED  
The Switch provides RMON capabilities that allow network administrators to  
set parameters and view statistical counters defined in MIB-II, Bridge MIB,  
and RMON MIB. RMON activities are performed at a Network Management  
Station running an SNMP network management application with graphical  
user interface.  
The Switch supports the following RMON MIB groups defined in RFC1757:  
• RMON Statistics Group maintains utilization and error statistics for the  
switch port being monitored.  
SNMP Agent and MIB-2 (RFC1213)  
• RMON History Group gathers and stores periodic statistical samples from  
the previous Statistics Group.  
The SNMP Agent running on the switch manager CPU is responsible  
for:  
• RMON Alarm Group allows a network administrator to define alarm  
thresholds for any MIB variable. An alarm can be associated with Low  
Threshold, High Threshold, or both. A trigger can trigger an alarm when the  
value of a specific MIB variable exceeds a threshold, falls below a thresh-  
old, or exceeds or falls below a threshold.  
• Retrieving MIB counters from various layers of software modules according  
to the SNMP GET/GET NEXT frame messages.  
• Setting MIB variables according to the SNMP SET frame message.  
• RMON Event Group allows a network administrator to define actions  
based on alarms. SNMP Traps are generated when RMON Alarms are trig-  
gered. The action taken in the Network Management Station depends on the  
specific network management application.  
• Generating an SNMP TRAP frame message to the Network Management  
Station if the threshold of a certain MIB counter is reached or if other trap  
conditions (see next page) are met:

BRIDGE GROUPS SUPPORTED  
Appendix  
The Switch supports the following four groups of Bridge MIB (RFC1493):  
About Fast Ethernet  
• The dot1dBase Group a mandatory group that contains the objects appli-  
cable to all types of bridges.  
As the demand for desktop video, multimedia development, imaging, and  
other speed-intensive applications continues to rise, the need for high per-  
formance, fault tolerant LAN technology will become more critical.  
• The dot1dStp Group contains the objects that denote the bridge's state,  
with respect to the Spanning Tree Protocol. If a node does not implement  
the Spanning Tree Protocol, this group will not be implemented. This group  
is applicable to any transparent only, source route, or SRT bridge that imple-  
ments the Spanning Tree Protocol.  
Standard Ethernet, which has been the most popular networking technology  
to date with a maximum data throughput of 10Mbps (Megabits per second),  
is becoming insufficient to handle the latest video, multimedia, and other  
speed-intensive client/server LAN applications.  
• The dot1dTp Group contains objects that describe the entity's transparent  
bridging status. This group is applicable to transparent operation only and  
SRT bridges.  
Among the solutions to the problem of network speed, Fast Ethernet has  
emerged as the most viable and economical. Capable of sending and receiv-  
ing data at 100Mbps, it is more than fast enough to handle even the most  
demanding video and other real-time applications.  
• The dot1dStatic Group contains objects that describe the entity's destina-  
tion-address filtering status. This group is applicable to any type of bridge  
which performs destination-address filtering.  
Although there are a number of different competing Fast Ethernet implemen-  
tations, 100BaseTX is by far the most popular. Operating on two pairs of  
Category 5 unshielded twisted-pair (UTP) cabling, 100BaseTX supports high  
speed signaling and is relatively inexpensive. Because it uses four wires for  
data transmission and the same packet format, packet length, error control,  
and management information as 10BaseT, 100BaseTX can be made to com-  
municate with slower 10BaseT equipment when routed through a switch.  
This backwards compatibility is one of 100BaseTX's major advantages over  
other forms of Fast Ethernet; it allows critical, speed-dependent network seg-  
ments to be upgraded to 100BaseTX speeds as needed without re-wiring,  
refitting, and retraining an entire site. Networks can now mix both slow and  
fast network segments for different users or departments. Publishing, R&D,  
video, multimedia, or accounting departments can enjoy a 100Mbps pace,  
while other corporate segments can operate at slower and more affordable  
10Mbps speeds.

Twisted-Pair Cabling  
About Gigabit Ethernet  
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times  
faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with  
100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hard-  
ware with either fiber optic cabling or copper Category 5 cabling, with fiber  
optics more suited for network backbones. As the new Gigabit standard grad-  
ually integrates into existing networks, current computer applications will  
enjoy faster access time for network data, hardware, and Internet connections.  
There are different grades, or categories, of twisted-pair cabling. Category 5  
is the most reliable and is highly recommended. Straight-through cables are  
used for connecting computers to a hub. Crossover cables are used for con-  
necting a hub to another hub (there is an exception: some hubs have a built-in  
uplink port that is crossed internally, which allows you to link or connect  
hubs together with a straight-through cable instead).  
You can buy pre-made Category 5  
cabling, or cut and crimp your own.  
Category 5 cables can be purchased  
or crimped as either straight-through  
or crossover cables. A Category 5  
cable has 8 thin, color-coded wires  
inside that run from one end of the  
cable to the other. All 8 wires are  
used. In a straight-through cable,  
wires 1, 2, 3, and 6 at one end of the  
cable are also wires 1, 2, 3, and 6 at  
the other end. In a crossover cable,  
the order of the wires change from  
one end to the other: wire 1 becomes  
3, and 2 becomes 6. See the diagrams  
on the next page for  
Fiber Optic Cabling  
Fiber optic cabling is made from flexible, optically efficient strands of glass  
and coated with a layer of rubber tubing, fiber optics use photons of light  
instead of electrons to send and receive data. Although fiber is physically  
capable of carrying tetrabits of data per second, the signaling hardware cur-  
rently on the market can handle no more than a few gigabits of data per sec-  
ond.  
Fiber cables come in different with two main connector types. The most com-  
monly used fiber optic cable is multi-mode fiber cable (MMF), with a 62.5  
micron fiber optic core. Single-mode fiber cabling is somewhat more effi-  
cient than multi-mode but far more expensive, due to its smaller optic core  
that helps retain the intensity of traveling light signals. A fiber connection  
always require two fiber cables: one transmits data, and the other receives it.  
more detailed informa-  
tion on straight-through  
Each fiber optic cable is tipped with a connector that fits into a fiber port on  
a network adapter, hub, or switch. In the U. S., most cables use a square SC  
connector that slides and locks into place when plugged into a port or con-  
nected to another cable. In Europe, the round ST connector is more prevalent.  
and crossover cabling.  
To determine which wire is wire number 1, hold the  
cable so that the end of the plastic RJ-45 tip (the part  
that goes into a wall jack first) is facing away from  
you. Face the clip down so that the copper side faces up  
(the springy clip will now be parallel to the  
floor).When looking down on the copper side, wire 1  
will be on the far left.

Glossary  
10BaseT - An Ethernet standard that uses twisted wire pairs.  
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs  
of Category 5 UTP or STP wire.  
1000BASE-T - provides half-duplex (CSMA/CD) and full-duplex 1000Mb/s  
Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-568-A.  
Topology rules for 1000BASE-T are the same as those used for 100BASE-T.  
Category 5 link lengths are limited to 100 meters by the ANSI/TIA/EIA-568-  
A cabling standard. Only one CSMA/CD repeater will be allowed in a colli-  
sion domain.  
802.1x - Based on the Extensible Authentication Protocol (EAP), the 802.1x  
standard is one of the IEEE standards for network authentication and key  
management. It establishes a framework that supports multiple authentication  
methods. This standard can be incorporated into any type of network to  
enhance its security.  
For example, a wireless user may use one of the authentication methods to  
access a wireless network protected by an authentication server. The user, also  
called the supplicant, sends a request to an access point or wireless router,  
also called the authenticator. The authenticator sends an identification request  
back to the user. After the user sends the authenticator the identification mes-  
sage, the authenticator forwards the user's identification message to the  
authentication server. If the server accepts the identification message, then  
the user is permitted access to the wireless network. The 802.1x standard can  
also support encryption key management to strengthen wireless network  
encryption services.  
Adapter - Printed circuit board that plugs into a PC to add to capabilities or  
connectivity to a PC. In a networked environment, a network interface card  
(NIC) is the typical adapter that allows the PC or server to connect to the  
intranet and/or Internet.  
Architecture - The total design and implementation of the network. It  
includes the network's topology, transmission technologies and communica-  
tions protocols, management and security systems, and any other attributes  
that give a network a particular set of capabilities and functionalities.  
ARP (Address Resolution Protocol) - A TCP/IP protocol used to figure out a  
host's Ethernet address (MAC address/node ID) from its Internet address.

Automatic Fall-back - A feature provided by some wireless products to  
Broadband - A data-transmission scheme in which multiple signals share the  
bandwidth of a medium. This allows the transmission of voice, data and video  
signals over a single medium. Cable television uses broadband techniques to  
deliver dozens of channels over one cable.  
increase connection reliability. Automatic fall-back enables a device to  
dynamically shift between various data transfer rates. It works by decreasing  
the data transfer rate when interference increases, distance increases, and  
other factors undermine signal strength and quality.  
Browser - A browser is an application program that provides a way to look at  
and interact with all the information on the World Wide Web or PC. The word  
"browser" seems to have originated prior to the Web as a generic term for  
user interfaces that let you browse text files online.  
Auto-MDI/MDIX - On a network hub or switch, an auto-MDI/MDIX port  
automatically senses if it needs to act as a MDI or MDIX port. The auto-  
MDI/MDIX capability eliminates the need for crossover cables.  
Auto-Sensing - To automatically determine the correct settings. The term is  
often used with communications and networking. For example, Ethernet  
10/100 cards, hubs and switches can determine the highest speed of the node  
they are connected to and adjust their transmission rate accordingly.  
BSS (Basic Service Set) - An infrastructure network connecting wireless  
devices to a wired network using a single access point.  
Buffer - A buffer is a shared or assigned memory area used by hardware  
devices or program processes that operate at different speeds or with different  
sets of priorities. The buffer allows each device or process to operate without  
being held up by the other. In order for a buffer to be effective, the size of the  
buffer and the algorithms for moving data into and out of the buffer need to  
be considered by the buffer designer. Like a cache, a buffer is a "midpoint  
holding place" but exists not so much to accelerate the speed of an activity as  
to support the coordination of separate activities.  
Backbone - The part of a network that connects most of the systems and net-  
works together and handles the most data.  
Bandwidth - The transmission capacity of a given facility, in terms of how  
much data the facility can transmit in a fixed amount of time; expressed in  
bits per second (bps).  
Beacon Interval - A beacon is a packet broadcast by the Access Point to  
keep the network synchronized. A beacon includes the wireless LAN service  
area, the AP address, the Broadcast destination addresses, a time stamp,  
Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM).  
CAT 5 - ANSI/EIA (American National Standards Institute/Electronic  
Industries Association) Standard 568 is one of several standards that specify  
"categories" (the singular is commonly referred to as "CAT") of twisted pair  
cabling systems (wires, junctions, and connectors) in terms of the data rates  
that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps  
and is usually utilized for 100BaseTX networks.  
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.  
Also, the smallest form of data.  
CAT 5e - The additional cabling performance parameters of return loss and  
far-end crosstalk (FEXT) specified for 1000BASE-T and not specified for  
10BASE-T and 100BASE-TX are related to differences in the signaling  
implementation. 10BASE-T and 100BASE-TX signaling is unidirectional-  
signals are transmitted in one direction on a single wire pair. In contrast,  
Gigabit Ethernet is bi-directional-signals are transmitted simultaneously in  
both directions on the same wire pair; that is, both the transmit and receive  
pair occupy the same wire pair.  
Boot - To cause the computer to start executing instructions. Personal com-  
puters contain built-in instructions in a ROM chip that are automatically exe-  
cuted on startup. These instructions search for the operating system, load it  
and pass control to it.  
Bottleneck - A traffic slowdown that results when too many network nodes  
try to access a single node, often a server node, at once.  
Bridge - A device that interconnects different networks together.  
Cookie - Data created by a Web server that is stored on a user's computer. It  
provides a way for the Web site to keep track of a user's patterns and prefer-  
ences and, with the cooperation of the Web browser, to store them on the  
user's own hard disk.

DHCP supports static addresses for computers containing Web servers that  
called the "processor," it is made up of the control unit and ALU.  
need a permanent IP address.  
Database - A database is a collection of data that is organized so that its con-  
tents can easily be accessed, managed, and updated.  
DMZ (Demilitarized Zone) - Allows one IP address (or computer) to be  
exposed to the Internet. Some applications require multiple TCP/IP ports to  
be open. It is recommended that you set your computer with a static IP  
address if you want to use DMZ Hosting.  
Data Packet - One frame in a packet-switched message. Most data communi-  
cations is based on dividing the transmitted message into packets. For exam-  
ple, an Ethernet packet can be from 64 to 1518 bytes in length.  
DNS - The domain name system (DNS) is the way that Internet domain name  
are located and translated into Internet Protocol (IP) addresses. A domain  
name is a meaningful and easy-to-remember "handle" for an Internet address.  
Default Gateway - The routing device used to forward all traffic that is not  
addressed to a station within the local subnet.  
Domain - A subnetwork comprised of a group of clients and servers under  
the control of one security database. Dividing LANs into domains improves  
performance and security.  
Denial of Service - A protocol that directs the network to no longer respond  
to requests that might arise as the result of a Denial of Service attack.  
Denial of Service Attack - An assault on a network that floods it with so  
many additional requests that regular traffic is either slowed or completely  
interrupted.  
Download - To receive a file transmitted over a network. In a communica-  
tions session, download means receive, upload means transmit.  
Driver - A workstation or server software module that provides an interface  
between a network interface card and the upper-layer protocol software run-  
ning in the computer; it is designed for a specific NIC, and is installed during  
the initial installation of a network-compatible client or server operating sys-  
tem.  
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network  
administrators manage centrally and automate the assignment of Internet  
Protocol (IP) addresses in an organization's network. Using the Internet's set  
of protocol (TCP/IP), each machine that can connect to the Internet needs a  
unique IP address. When an organization sets up its computer users with a  
connection to the Internet, an IP address must be assigned to each machine.  
Without DHCP, the IP address must be entered manually at each computer  
and, if computers move to another location in another part of the network, a  
new IP address must be entered. DHCP lets a network administrator super-  
vise and distribute IP addresses from a central point and automatically sends  
a new IP address when a computer is plugged into a different place in the net-  
work.  
DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit  
pattern for all data transmitted. This bit pattern is called a chip (or chipping  
code). Even if one or more bits in the chip are damaged during transmission,  
statistical techniques embedded in the receiver can recover the original data  
without the need for retransmission. To an unintended receiver, DSSS appears  
as low power wideband noise and is rejected (ignored) by most narrowband  
receivers. However, to an intended receiver (i.e. another wireless LAN end-  
point), the DSSS signal is recognized as the only valid signal, and interfer-  
ence is inherently rejected (ignored).  
DHCP uses the concept of a "lease" or amount of time that a given IP address  
will be valid for a computer. The lease time can vary depending on how long  
a user is likely to require the Internet connection at a particular location. It's  
especially useful in education and other environments where users change  
frequently. Using very short leases, DHCP can dynamically reconfigure net-  
works in which there are more computers than there are available IP address-  
es.  
Dynamic IP Address - An IP address that is automatically assigned to a  
client station in a TCP/IP network, typically by a DHCP server. Network  
devices that serve multiple users, such as servers and printers, are usually  
assigned static IP addresses.

Dynamic Routing - The ability for a router to forward data via a different  
route based on the current conditions of the communications circuits. For  
example, it can adjust for overloaded traffic or failing lines and is much more  
flexible than static routing, which uses a fixed forwarding path.  
Firewall - A firewall is a set of related programs, located at a network gate-  
way server, that protects the resources of a network from users from other  
networks. (The term also implies the security policy that is used with the pro-  
grams.) An enterprise with an intranet that allows its workers access to the  
wider Internet installs a firewall to prevent outsiders from accessing its own  
private data resources and for controlling what outside resources to which its  
own users have access.  
Encryption - A security method that applies a specific algorithm to data in  
order to alter the data's appearance and prevent other devices from reading  
the information.  
Basically, a firewall, working closely with a router, examines each network  
packet to determine whether to forward it toward its destination.  
ESS (Extended Service Set) - A set of more than two or more BSSs (multiple  
access points) forming a single network.  
Firmware - Code that is written onto read-only memory (ROM) or program-  
mable read-only memory (PROM). Once firmware has been written onto the  
ROM or PROM, it is retained even when the device is turned off.  
Ethernet - IEEE standard network protocol that specifies how data is placed  
on and retrieved from a common transmission medium. Has a transfer rate of  
10 Mbps. Forms the underlying transport vehicle used by several upper-level  
protocols, including TCP/IP and XNS.  
Fragmentation - Breaking a packet into smaller units when transmitting over  
a network medium that cannot support the original size of the packet.  
Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet  
CSMA/CD network access method.  
FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IP  
network (Internet, UNIX, etc.). For example, after developing the HTML  
pages for a Web site on a local machine, they are typically uploaded to the  
Web server using FTP.  
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes  
(hops) the carrier frequency of a conventional carrier several times per second  
according to a pseudo-random set of channels. Because a fixed frequency is  
not used, and only the transmitter and receiver know the hop patterns, inter-  
ception of FHSS is extremely difficult.  
FTP includes functions to log onto the network, list directories and copy files.  
It can also convert between the ASCII and EBCDIC character codes. FTP  
operations can be performed by typing commands at a command prompt or  
via an FTP utility running under a graphical interface such as Windows. FTP  
transfers can also be initiated from within a Web browser by entering the  
URL preceded with ftp://.  
Fiber Optic - The medium and the technology associated with the transmis-  
sion of information as light impulses along a glass or plastic wire or fiber.  
Fiber optic wire carries much more information over longer distances than  
conventional copper wire and is far less subject to electromagnetic interfer-  
ence.  
Unlike e-mail programs in which graphics and program files have to be  
"attached," FTP is designed to handle binary files directly and does not add  
the overhead of encoding and decoding the data.  
Fiber Optic Cable - A transmission medium that uses glass or plastic fibers  
rather than copper wire to transport data or voice signals. The signal is  
imposed on the fibers via pulses (modulation) of light from a laser or a light-  
emitting diode (LED). Because of its high bandwidth and lack of susceptibili-  
ty to interference, fiber optic cable is used in long-haul or noisy applications.  
Full Duplex - The ability of a device or line to transmit data simultaneously  
in both directions.  
Gateway - A device that interconnects networks with different, incompatible  
Finger - A UNIX command widely used on the Internet to find out informa-  
tion about a particular user, such as telephone number, whether currently  
logged on or the last time logged on. The person being "fingered" must have  
placed his or her profile on the system. Fingering requires entering the full  
user@domain address.

Half Duplex - Data transmission that can occur in two directions over a sin-  
gle line, but only one direction at a time.  
IKE (Internet Key Exchange) - A negotiation and key exchange protocol  
specified by the Internet Engineering Task Force. An IKE security association  
(SA) automatically negotiates encryption and authentication keys. With IKE,  
an initial exchange authenticates the VPN session and automatically negoti-  
ates keys that will be used to pass encrypted data over the Internet or any  
other network.  
Hardware - Hardware is the physical aspect of computers, telecommunica-  
tions, and other information technology devices. The term arose as a way to  
distinguish the "box" and the electronic circuitry and components of a com-  
puter from the program you put in it to make it do things. The program came  
to be known as the software.  
In-Band Management - Management of the network from a station attached  
directly to the network.  
Hop - The link between two network nodes.  
IP (Internet Protocol) - The method or protocol by which data is sent from  
one computer to another on the Internet. It is a standard set of rules, proce-  
dures, or conventions relating to the format and timing of data transmission  
between two computers that they must accept and use to be able to under-  
stand each other.  
HTTP (HyperText Transport Protocol) - The communications protocol used  
to connect to servers on the World Wide Web. Its primary function is to estab-  
lish a connection with a Web server and transmit HTML pages to the client  
browser.  
Hub - The device that serves as the central location for attaching wires from  
workstations. Can be passive, where there is no amplification of the signals;  
or active, where the hubs are used like repeaters to provide an extension of  
the cable that connects to a workstation.  
IP Address - In the most widely installed level of the Internet Protocol (IP)  
today, an IP address is a 32-binary digit number that identifies each sender or  
receiver of information that is sent in packet across the Internet. When you  
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP  
includes your IP address in the message (actually, in each of the packets if  
more than one is required) and sends it to the IP address that is obtained by  
looking up the domain name in the Uniform Resource Locator you requested  
or in the e-mail address you're sending a note to. At the other end, the recipi-  
ent can see the IP address of the Web page requestor or the e-mail sender and  
can respond by sending another message using the IP address it received.  
ICMP (Internet Control Message Protocol) - Part of the TCP/IP protocol.  
Network devices such as routers or servers use ICMP to transmit error mes-  
sages and control messages. For example, the PING program uses ICMP.  
IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE  
describes itself as "the world's largest technical professional society, promot-  
ing the development and application of electrotechnology and allied sciences  
for the benefit of humanity, the advancement of the profession, and the well-  
being of our members."  
IPCONFIG - A Windows NT or 2000 utility that provides for querying,  
defining and managing IP addresses within a network. A commonly used  
utility for configuring networks with static IP addresses.  
The IEEE fosters the development of standards that often become national  
and international standards. The organization publishes a number of journals,  
has many local chapters, and several large societies in special areas, such as  
the IEEE Computer Society.  
IP Multicast Filtering - A process whereby the switch can pass multicast  
traffic along to participating hosts.  
IPSec (Internet Protocol Security) - A suite of protocols used to implement  
secure exchange of packets at the IP layer. IPSec supports two basic modes:  
Transport and Tunnel. Transport encrypts the payload of each packet, leaving  
the header untouched, while Tunnel mode encrypts both the header and the  
payload and is therefore more secure. IPSec must be supported on both  
transmitter and receiver and must share a public key. Tunnel mode is widely  
deployed in VPNs (Virtual Private Networks).  
IGMP (Internet Group Management Protocol) - A multicast host registration  
protocol that allows any host to inform its local router that it wants to receive  
transmissions addresses to a specific multicast group. If there is more than  
one multicast router on a given subnetwork, one of the routers is elected  
"querier" and assumes the responsibility of keeping track of group member-  
ship.

LAN (Local Area Network) - A group of computers and associated devices  
that share a common communications line and typically share the resources  
of a single processor or server within a small geographic area (for example,  
within an office building).  
Network - A system that transmits any combination of voice, video and/or  
data between users.  
Node - A network junction or connection point, typically a computer or work  
station.  
Latency - The time delay between when the first bit of a packet is received  
and the last bit is forwarded.  
Out-of-Band Management - Management of the network from a station not  
attached to the network.  
Layer 2 - Data Link layer in the International Standards Organization (ISO)  
7-Layer Data Communications Protocol, also known as the OSI (Open  
Systems Interconnection) model. This is a standard model to consult when  
designing network protocols. Layer 2 is directly related to the hardware inter-  
face for network devices and passes traffic based on MAC addresses.  
Packet - A unit of data routed between an origin and a destination in a net-  
work.  
Packet Filtering - Discarding unwanted network traffic based on its originat-  
ing address or range of addresses or its type (e-mail, file transfer, etc.).  
Layer 3 - Network layer in the International Standards Organization (ISO) 7-  
Layer Data Communications Protocol, also known as the OSI (Open Systems  
Interconnection) model. This is a standard model to consult when designing  
network protocols. Layer 3 handles the routing functions for data moving  
from one open system to another.  
Ping (Packet INternet Groper) - An Internet utility used to determine whether  
a particular IP address is online. It is used to test and debug a network by  
sending out a packet and waiting for a response.  
Port - A pathway into and out of the computer or a network device such as a  
switch or router. For example, the serial and parallel ports on a personal com-  
puter are external sockets for plugging in communications lines, modems and  
printers.  
MAC (Media Access Control) Address - A unique number assigned by the  
manufacturer to any Ethernet networking device, such as a network adapter,  
that allows the network to identify it at the hardware level.  
Mbps (Megabits per second) - One million bits per second; unit of measure-  
ment for data transmission.  
Port Mirroring - Port mirroring, also known as a roving analysis port, is a  
method of monitoring network traffic that forwards a copy of each incoming  
and outgoing packet from one port of a network switch to another port where  
the packet can be studied. A network administrator uses port mirroring as a  
diagnostic tool or debugging feature, especially when fending off an attack. It  
enables the administrator to keep close track of switch performance and alter  
it if necessary. Port mirroring can be managed locally or remotely.  
MDI (Medium Dependent Interface) - On a network hub or switch, a MDI  
port, also known as an uplink port, connects to another hub or switch using a  
straight-through cable. To connect a MDI port to a computer, use a crossover  
cable.  
MDIX (Medium Dependent Interface Crossed) - On a network hub or switch,  
a MDIX port connects to a computer using a straight-through cable. To con-  
nect a MDIX port to another hub or switch, use a crossover cable.  
Port Trunk - Defines a network link aggregation and trunking method, which  
specifies how to create a single high-speed logical link that combines several  
lower-speed physical links.  
MIB (Management Information Base) - A set of database objects. This set  
contains information about a specific device for utilizing SNMP.  
QoS (Quality of Service) - A wide variety of techniques that prioritizes spe-  
cific types of network traffic. QoS is used to maximize a network's perform-  
ance according to its requirements. QoS ensures better service to high-priori-  
ty types of network traffic, which may involve demanding, real-time applica-  
tions, such as videoconferencing.  
Multicasting - Sending data to a group of nodes instead of a single destina-  
tion.

RAID improves performance by disk striping, which interleaves bytes or  
groups of bytes across multiple drives, so more than one disk is reading and  
writing simultaneously.  
SPI (Stateful Packet Inspection) - A firewall technology that monitors the  
state of the transaction so that it can verify that the destination of an inbound  
packet matches the source of a previous outbound request. It examines not  
just the headers of the packet, but also the contents, to determine more about  
the packet than just its source and destination information. It is called "state-  
ful" because verifies that the stated destination computer has previously  
requested the current communication. In this way, it verifies that all commu-  
nications are initiated by the recipient computer and are taking place only  
with sources that are known and trusted from previous interactions. In addi-  
tion to being a more rigorous inspection, stateful packet inspection closes off  
ports until connection to the specific port is requested. This allows an added  
layer of protection from the threat of port scanning.  
RIP (Routing Information Protocol) - A simple routing protocol that is part  
of the TCP/IP protocol suite. It determines a route based on the smallest hop  
count between source and destination. RIP is a distance vector protocol that  
routinely broadcasts routing information to its neighboring routers.  
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector  
that holds up to eight wires, used for connecting Ethernet devices.  
RMON (Remote MONitoring) - RMON provides comprehensive network  
monitoring capabilities. It eliminates the polling required in standard SNMP,  
and can set alarms on a variety of traffic conditions, including specific error  
types.  
Static Routing - Forwarding data in a network via a fixed path. Static routing  
cannot adjust to changing line conditions as can dynamic routing.  
Storage - The semi-permanent or permanent holding place for digital data.  
Server - Any computer whose function in a network is to provide user access  
to files, printing, communications, and other services.  
STP - 1. (Shielded Twisted Pair) Telephone wire that is wrapped in a metal  
sheath to eliminate external interference. 2. (Spanning Tree Protocol) A tech-  
nology that checks your network for any loops. A loop can often occur in  
complicated or back-up linked network systems. Spanning-tree detects and  
directs data along the shortest path, maximizing the performance and effi-  
ciency of the network.  
SMTP (Simple Mail Transfer Protocol) - The standard e-mail protocol on  
the Internet. It is a TCP/IP protocol that defines the message format and the  
message transfer agent (MTA), which stores and forwards the mail.  
SNMP (Simple Network Management Protocol) - A widely used network  
monitoring and control protocol. Data is passed from SNMP agents, which  
are hardware and/or software processes reporting activity in each network  
device (hub, router, bridge, etc.) to the workstation console used to oversee  
the network. The agents return information contained in a MIB (Management  
Information Base), which is a data structure that defines what is obtainable  
from the device and what can be controlled (turned off, on, etc.).  
Subnet Mask - The method used for splitting IP networks into a series of  
subgroups, or subnets. The mask is a binary pattern that is matched up with  
the IP address to turn part of the host ID address field into a field for subnets.  
Swapping - Replacing one segment of a program in memory with another  
and restoring it back to the original when required.  
Software - Instructions for the computer. A series of instructions that per-  
forms a particular task is called a "program." The two major categories of  
software are "system software" and "application software." System software  
is made up of control programs such as the operating system and database  
management system (DBMS). Application software is any program that  
processes data for the user.  
Switch - 1. A data switch connects computing devices to host computers,  
allowing a large number of devices to share a limited number of ports. 2. A  
device for making, breaking, or changing the connections in an electrical cir-  
cuit.  
A common misconception is that software is data. It is not. Software tells the  
hardware how to process the data.

TCP (Transmission Control Protocol) - A method (protocol) used along with  
the IP (Internet Protocol) to send data in the form of message units (data-  
gram) between network devices over a LAN or WAN. While IP takes care of  
handling the actual delivery of the data (routing), TCP takes care of keeping  
track of the individual units of data (called packets) that a message is divided  
into for efficient delivery over the network. TCP is known as a "connection  
oriented" protocol due to requiring the receiver of a packet to return an  
acknowledgment of receipt to the sender of the packet resulting in transmis-  
sion control.  
Upgrade - To replace existing software or firmware with a newer version.  
Upload - To transmit a file over a network. In a communications session,  
upload means transmit, download means receive.  
UTP - Unshielded twisted pair is the most common kind of copper telephone  
wiring. Twisted pair is the ordinary copper wire that connects home and many  
business computers to the telephone company. To reduce crosstalk or electro-  
magnetic induction between pairs of wires, two insulated copper wires are  
twisted around each other. Each signal on twisted pair requires both wires.  
Since some telephone sets or desktop locations require multiple connections,  
twisted pair is sometimes installed in two or more pairs, all within a single  
cable.  
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com-  
munication language or set of protocols for communications over a network  
(developed specifically for the Internet). TCP/IP defines a suite or group of  
protocols and not only TCP and IP.  
VLAN (Virtual LAN) - A logical association that allows users to communi-  
cate as if they were physically connected to a single LAN, independent of the  
actual physical configuration of the network.  
Telnet - A terminal emulation protocol commonly used on the Internet and  
TCP/IP-based networks. It allows a user at a terminal or computer to log onto  
a remote device and run a program.  
Throughput - The amount of data moved successfully from one place to  
another in a given time period.  
Topology - A network's topology is a logical characterization of how the  
devices on the network are connected and the distances between them. The  
most common network devices include hubs, switches, routers, and gateways.  
Most large networks contain several levels of interconnection, the most  
important of which include edge connections, backbone connections, and  
wide-area connections.  
TX Rate - Transmission Rate.  
UDP (User Datagram Protocol) - A method (protocol) used along with the IP  
(Internet Protocol) to send data in the form of message units (datagram)  
between network devices over a LAN or WAN. While IP takes care of han-  
dling the actual delivery of the data (routing), UDP takes care of keeping  
track of the individual units of data (called packets) that a message is divided  
into for efficient delivery over the network. UDP is known as a "connection-  
less" protocol due to NOT requiring the receiver of a packet to return an  
acknowledgment of receipt to the sender of the packet (as opposed to TCP).
