Introduction  
Introduction  
This chapter introduces the Agilent 4986B Ethernet LanProbe (shown in Figure 1-  
1 on page 2), including its installation and configuration options.  
You can use your LanProbe with NetMetrix/UX (for HP-UX and Solaris) The  
term “NetMetrix” is used in this manual to refer to Agilent NetMetrix/UX.  
The following sections are included in this chapter:  
“Installation and Configuration Overview” on page 4  
“LanProbe Overview” on page 5  
The Agilent 4986B Ethernet LanProbe is a Motorola 68040-based, SNMP-  
managed segment monitor for distributed Ethernet networks. Its network interface  
(port) consists of a single RJ-45 connector.

Introduction  
The Ethernet LanProbe has 16 MB of memory (optionally 32 MB), and uses  
FLASH EPROM. Future upgrades to LanProbe’s firmware are easily downloaded  
over the LAN to multiple probes simultaneously. You can also download  
firmware using LanProbe’s serial port.  
LanProbe maintains a variety of statistical measurements on network  
performance, continuously keeping track of traffic levels, errors, and other  
important trends. Alarm thresholds can be set on any of these parameters,  
immediately alerting the network manager or initiating a packet trace to capture  
the details of the event for later analysis. Traffic and error levels are also  
monitored per node for each station on the segment.  
Private MIB extensions give LanProbe additional capabilities beyond RMON.  
Multiple SNMP trap addresses, or groups of addresses, can be defined for event  
notification. The probe maps MAC addresses to IP addresses for node  
identification, and provides duplicate IP address detection. A real time utilization  
variable has been added, which provides the ability to alarm on instantaneous  
peaks of network load. An additional Out-of-Band connection to the probe can be  
established using Serial Link Internet Protocol (SLIP), either directly, using a  
modem, or by using a data switch.  
You can configure the LanProbe to perform Echo Test Monitoring (tests to verify  
communications) of network nodes from your network management station.  
LanProbe allows the network manager to select one or several nodes to perform a  
one-time test or specify an interval for periodic testing. You can view the results  
of the Echo Test Monitoring from your NetMetrix management console. This can  
be very useful for monitoring critical nodes to verify connectivity. This test can  
also be performed from several points on the network (using several LanProbes)  
to verify connectivity from each point. When a node becomes unreachable an alert  
can be sent from LanProbe to your management station. To provide testing of a  
large range of nodes, Echo Test Monitoring supports ICMP, IEEE 802.2, and  
IEEE 802.3 for Novell IPX. This extension is supported by the NetMetrix  
software.

Introduction  
LanProbe Overview  
LanProbe also contains the Agilent Private MIB which allows for configuration  
and administration of the probe. It provides enhanced authentication features,  
specification of trap destinations, remote download of new firmware revisions,  
serial line control, and other features. The Agilent Private MIB is available  
electronically with NetMetrix.  
You can refer to Table B-8 on page 104 for specific information on your probe’s  
protocol directory.  
Management Stations  
Management stations gather network data collected by Agilent LanProbes. They  
present this information in easy-to-use and easy-to-understand text and graphic  
formats. You can use a management station to communicate with your LanProbe  
after it has been installed and configured.  
The LanProbe communicates with the NetMetrix software running on your  
management station. NetMetrix management applications allow you to review  
and reconfigure LanProbe parameters (such as IP address, trap destinations,  
filters, and packet captures), to manage the information collected by LanProbe  
(including statistics, historical studies, alarms, packet size distribution, and  
captured packet traces), and to monitor local or remote networks (by gathering  
network statistics from Agilent LanProbe agents as network monitors).  
Refer to your NetMetrix documentation for more information.  
Access Security  
The LanProbe configuration menu allows network administrators to disable  
standard RMON functions which could be considered a security risk. The security  
menu allows network administrators to disable the RMON-1 packet capture  
capabilities of LanProbe to prevent network users from viewing network traffic.  
TFTP firmware downloads can be disabled to prevent users from downloading  
earlier versions of the LanProbe firmware which did not support these new  
security features. For more information, refer to “Modify/View Security Values”  
on page 20.

Introduction  
LanProbe Overview  
The LanProbe private MIB uses a four-level access control scheme. An access  
level is assigned for each community string to be used with LanProbe. The access  
level is an integer value between one and four, with increasing degrees of  
authorization granted for higher authorization numbers. Each higher level is  
granted the rights of all lower levels in addition to the specific privileges of that  
level. Table 1-1 shows specific access privileges by level.

CONFIG Button  
The CONFIG button is used to configure LanProbe from a terminal or to restart  
the probe. The CONFIG button is recessed and located on the back of the probe  
near the RS-232C connector. You will need to use a narrow, pointed object (like a  
pen) to press the CONFIG button.  
To configure LanProbe using a local terminal (or PC emulating a terminal),  
connect a terminal to LanProbe using a null modem cable and push the CONFIG  
button to display LanProbe’s Main Menu. This operation is described in Chapter 2  
“Local Terminal Configuration”.  
You can restart the probe (with a warm start or cold start) using the CONFIG  
button. These functions are described in Chapter 5 “LanProbe Operation”.

Installation  
Selecting a Location  
Selecting a Location  
Select a location for your LanProbe where it will be the most useful. The  
LanProbe can only monitor traffic that is present on the LAN where it is attached.  
Because interconnect devices (bridges, for example) filter traffic, a LanProbe may  
need to be attached on each side of an interconnect device for complete collection  
of network statistics. In this respect, the placement of LanProbe affects the  
statistics collected.  
Consider the following installation requirements when selecting a location for  
your probe:  
NOTE  
The Fault and Activity LEDs on the front of LanProbe will light if any of the  
individual port LEDs on the rear panel light. To determine which port has activity  
or a fault, you are required to look at the port LEDs on the back panel. This should  
be considered when selecting a location or LanProbe’s orientation in a rack.  
A flat surface that is large enough to support the probe (requires clearance at  
rear and sides for cooling and rear panel access), adequate wall space, or  
space in a 19 inch rack or cabinet.  
A grounded power outlet (either 100-120/VAC or 220-240/VAC).  
Access to one or more Ethernet connection taps.  
Access to an RS-232C connection (required only for Out-of-Band

Access to a phone line and a modem within 50 feet (required only for Out-  
of-Band communication using a modem connection).  
NOTE  
The MAC address for the probe can be found on the rear label. It is a good idea to  
make a note of this address prior to installing your LanProbe because some  
installation methods make it difficult to see the rear label without removing the  
probe.

Installation  
Connecting the Probe  
Connecting the Probe  
LanProbe communicates with Agilent NetMetrix either through the In-Band  
network connection or by using an Out-of-Band serial connection. You can  
establish both In-Band and Out-of-Band connections to give you the option of  
communicating with the probe either over the network or over the serial link,  
respectively.  
The In-Band connection adds a slight amount of traffic to the network, but is  
faster than the Out-of-Band connection. The disadvantage of using only the  
In-Band connection is that certain network or component failures can result in loss  
of communication with LanProbe.  
The Out-of-Band serial connection can be used as the primary means of  
communication or as a backup link in case of a network failure. The disadvantage  
of using only the Out-of-Band connection is that it is a slower means of  
communications.  
Connecting to the Network (In-Band)  
You can connect LanProbe to the network by connecting the 10Base-T (RJ-45)  
port. Figure 3-13 on page 38 shows the rear panel of LanProbe.  
CAUTION  
Do not touch the probe connector pins or the cable connector pins. Static  
discharge may damage equipment.

Configure the Management Station and LanProbe  
Refer to your NetMetrix documentation for information on configuring the  
management station for use with a modem. Verify that the packet retransmission  
timeout is set appropriately. For example, a 1500-byte SNMP packet requires  
about one second to transmit over a 9600 baud connection, with another one  
second for the reply. A packet retransmission timeout of three to five seconds is  
appropriate for this example.

Installation  
Connecting the Probe  
The LanProbe can be configured for Serial Line Internet Protocol (SLIP) link  
communications either by using a local terminal through the serial port or by  
using a NetMetrix management station over the network.  
If you use the network to configure LanProbe, make the network connection (refer  
to “Connecting to the Network (In-Band)” on page 37) and then refer to your  
NetMetrix documentation to configure the following LanProbe parameters:  
Serial Port IP Address  
Serial Port Speed  
Hardware Flow Control (if unsure, consult your modem’s documentation)  
Modem Init String  
If you use an ASCII terminal to configure LanProbe as described in Chapter 2  
“Local Terminal Configuration”, attach the terminal and configure the following  
LanProbe parameters:  
Serial Port IP Address  
Serial Port Subnet Mask  
Serial Port Speed  
Hardware Flow Control (if unsure, ask your local network administrator)  
Modem Init String  
The Serial Port IP Address must be on the same IP subnet as the management  
station’s serial IP address.  
Normally, each company has one subnet mask that is used for all machines on  
their network. Enter this subnet mask value into the Serial Port Subnet Mask  
field. The Serial Subnet Mask used for the probe should match the subnet mask  
used for the SLIP port on the management station.  
Set the Serial Port Speed to a value that is less than or equal to the maximum  
speed at which your modem can operate.  
Set the Hardware Flow Control to Off (On is the default), unless you are using  
high speed modems (14.4K baud or faster) with advanced features, such as error  
correction and data compression. If the Hardware Flow Control is set to On, you  
can set it to Off by using LanProbe’s menu or over the network from a NetMetrix  
management station (refer to your NetMetrix documentation for details).

Installation  
Connecting the Probe  
Verify that the Modem Init String is properly initialized for the attached modem  
by referencing the modem’s documentation. The probe’s default modem  
initialization string is configured to work with low-speed and medium-speed  
Hayes compatible modems. The following modem settings are recommended for  
low-speed to medium-speed modem connections:  
Modem Flow Control:  
Data Compression (if applicable):  
Error Correction (if applicable):  
Off  
Off  
Off  
Not all Hayes commands are the same for all Hayes-compatible modems. Refer  
to your modem’s documentation to determine the commands required for each of  
the above settings and append these commands to the end of the default Modem  
Init String.  
NOTE  
Your modem’s documentation discusses the features that are relevant to your  
modem. If your modem does not support a feature (data compression, for  
example), you do not need to turn it off in the Modem Init String.  
Some modems require you to set register values explicitly, rather than sending  
Hayes style commands. In this case, follow your modem’s documentation to set  
these registers.  
If you are using a high-speed modem, you probably need to modify the default  
modem initialization string. The following modem settings are recommended for  
high-speed modem connections:  
Modem Flow Control:  
Carrier Detect:  
Data Compression:  
Error Correction:  
Hardware Flow Control (RTS/CTS signaling)  
Always On  
Enabled  
Enabled  
After appending the appropriate commands to the modem initialization string,  
warm start your LanProbe.  
Refer to your NetMetrix documentation for information on how to establish  
communications with LanProbe over the SLIP link.

Installation  
Connecting the Probe  
Data Switch Connection  
Use the data switch connection to provide the flexibility of using more than one  
management station to communicate with more than one LanProbe.  
To make a data switch connection to LanProbe, connect a NetMetrix management  
station to LanProbe’s RS-232C port through a data switch. Set the Serial Port  
Mode to Direct, if your probe is directly connected to the data switch, or set it to  
Modem, if your probe must dial through a modem to another modem that is  
attached to the data switch.  
To allow traps to be sent from the probe to your management station, specify a  
Serial Trap Destination of type Switch or Modem Switch, using NetMetrix.  
Refer to your data switch documentation for information on setting up your data  
switch. There are many variations available for this connection method. Figure 3-  
17 on page 46 shows a possible data switch connection scheme.

Chapter 4 “Bootp Server Configuration”.  
If you used the local terminal method of configuration, attach the power cord and  
Agilent Power Module to LanProbe. The probe does not have a power switch, but  
is powered on when power is attached. When powered on or reset, LanProbe runs  
self-tests and transmits ICMP echo frames to the default gateway for the purpose  
of allowing the probe to be discovered by the routers (ARP cache). The probe  
transmits four ICMP echo request packets about 10 seconds after booting and  
again every autodiscovery echo interval. Refer to Chapter 5 “LanProbe  
Operation” for more information on resetting the probe.

Verifying the Installation  
Verifying the Installation  
You can verify the LanProbe installation by looking at the status LEDs on the  
front of the probe. After the LanProbe restarts (boots), it runs a power-on self-test  
(POST) and then starts normal operations.  
The Fault LED is briefly turned on (about three seconds) during the POST. After  
LanProbe passes the POST, the Fault LED turns off. The Activity LED flashes  
during network activity. The ~Line On or Power LED should be on to indicate that  
power is applied to the probe.  
After LanProbe has passed its self-tests, look at the status LEDs to verify your  
installation. The status LEDs should be in the following states:  
LED  
State  
Activity  
Flashing, if connected to a network with traffic, or may  
appear to stay on solid during periods of steady traffic.  
~ Line On or Power  
Fault  
On solid  
Off

Bootp Server Configuration  
Probe Configuration Using a Bootp Server  
Probe Configuration Using a Bootp Server  
You can use a Bootstrap Protocol(Bootp*) server to load LanProbe’s IP  
configuration. This method requires that a Bootp server maintains a file  
containing client configuration information, maps from MAC addresses to IP  
addresses, and responds to requests from clients. You can configure the probe  
from an HP-UX, Solaris, or MS-DOS system acting as a Bootp server. The system  
that is operating as the Bootp server must be connected to your network. Table 4-2  
on page 54 shows the minimum requirements for a Bootp server operating on HP  
9000, Sun SPARC, and PC systems.  
Before you can use the Bootp server, you must edit the bootptab file to configure  
the required LanProbe parameters. Refer to “Configuring the Bootptab File” on  
page 65 for more information.  
LanProbe’s MAC address is twelve characters long and is printed on a tag on the  
back of the probe. You must determine the IP Address, Default Gateway IP  
Address, and Subnet Mask from the network.  
To allow LanProbe to use a Bootp server that is not on the same subnet, the router  
involved must support Bootp Relay (the transfer of a Bootp request). For example,  
if you have multiple LanProbes that you want to configure from a single Bootp  
server, be sure that the routers in the path between your Bootp server and the  
LanProbes support Bootp Relay. Otherwise, you will need to operate the Bootp  
server on the same subnet as your LanProbes. You can configure multiple  
LanProbes on one subnet and then place them on their respective segments.

Bootp Server Setup on an HP or Sun System  
If your Bootp server is an HP-UX or Solaris system, use the following instructions  
to configure LanProbe:  
1. Determine the IP address to be used for LanProbe.  
2. Determine the name to be used as LanProbe’s Domain Name Services (refer  
to the HP ARPA Services manual) or configure an IP address and name for  
LanProbe in your local /etc/hosts file.  
3. Make sure that the Bootp server can communicate with LanProbe (if they  
are separated by a router, the router must support Bootp Relay).  
4. From the Bootp server, edit the client configuration file and enter the  
following parameters to be used for LanProbe (do not specify any other  
parameters):  
MAC Address  
IP Address  
Default Gateway IP Address (if available)  
Subnet Mask  
NOTE  
The Bootp server must support the vendor specific subnet mask field and the  
default gateway field.  
5. Start the Bootp daemon as described in “Starting the Bootp Server on an HP  
or Sun System” on page 57.  
6. Connect the power cord and Agilent Power Module (0950-2546) to  
LanProbe and to a power source (either 100-120/VAC or 220-240/VAC).  
LanProbe does not have a power switch but becomes operational when  
power is attached.

The probe automatically broadcasts Bootp requestswhen its IP address is  
0.0.0.0(the default). The probe broadcasts Bootp requests to signal its  
need to be configured.  
7. For HP-UX systems: Log in as root, then use SAM to follow the instructions  
presented on the screen.  
For HP-UX 9.x, choose:  
Networking/Communications -> Service:Enable/Disable  
For HP-UX 10.x and 11.x, choose:  
Networking and Communications -> Network Services  
NOTE  
If the last screen presented in Step 7 displays bootp server enabled, (for  
either HP-UX 9.x, HP-UX 10.x, or HP-UX 11.x) then your machine is already set  
up as a bootp server.  
8. Edit the /etc/bootptabfile to configure the probe and add descriptive  
comments to the file for reference. Refer to “Configuring the Bootptab File”  
on page 65, the bootpd(1M)man page or the HP ARPA Services manual  
for more information on configuring the /etc/bootptab file.  
9. Use tail -fto check the system log file to ensure that the Bootp server  
responded correctly to the Bootp request. The log file is /var/adm/  
messages(Solaris), /usr/adm/syslog(HP-UX 9.x), or /usr/  
adm/syslog/syslog.log(HP-UX 10.x and 11.x).  
10. If you are using HP OpenView, you can verify that LanProbe has been  
assigned the correct IP address and shows up on the management station  
map as a network analyzer. The discovery process that places LanProbe in  
the management station map can take several minutes to complete.  
NOTE  
You may be able to decrease the required time for discovery of LanProbe by  
pinging it continuously from your Agilent NetMetrix management station. You  
can also ping LanProbe to verify that it responds to the new IP address.

As a TSR (terminate-and-stay-resident) program by entering the following:  
bootpd -a IP address  
63  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Bootp Server Configuration  
Bootp Server Setup on a PC  
Where:  
-a IP address is required and specifies the IP address of the PC where you are  
running bootpd.  
-s specifies that you are running bootpd as a standalone executable (not as a  
TSR). You may want to use the -s option if you do not need the Bootp daemon  
to continually service bootp requests. This is preferable, since the Bootpd TSR  
may consume a large amount of memory (depending on the size of your  
bootptab file).  
Upon startup, Bootpd reads the bootptab file and then listens for bootp request  
packets from the network. Bootpd re-reads the bootptab file when it receives a  
bootp request packet and detects that the file has been updated. If hosts are added,  
deleted, or modified, their entries in Bootpd’s internal database are also updated  
when the bootptab file is re-read. All Bootp status messages are logged to the  
BOOTPD.LOG file.  
You can now attach the power cord and Agilent Power Module (0950-2546) to  
LanProbe and to a power source (either 100-120/VAC or 220-240/VAC).  
LanProbe does not have a power switch but becomes operational when power is  
attached. When powered on and when its IP address is 0.0.0.0(the default),  
LanProbe automatically broadcasts Bootp requests that trigger the Bootp server to  
provide its configuration parameters.

Restarting the Probe  
The LanProbe can be restarted by performing a warm start or a cold start. In  
either case, the probe executes self-tests and re-initializes. There are differences in  
the effects of each type of restart.  
A warm start resets LanProbe’s measurement data only.  
A cold start resets all of LanProbe’s measurement data, filters, alarms, and  
user-defined statistics studies (excluding communications configuration  
parameters) back to default values.  
Warm Start  
A warm start resets LanProbe’s measurement data only. You can warm start  
Cycling power (or a power outage).  
Selecting the menu item Warm start and Exit from LanProbe’s Main Menu  
when you have a local terminal connected to the probe, as described in Step  
3 on page 74.  
Using Agilent NetMetrix to execute a LanProbe warm start. Refer to your  
NetMetrix documentation for details.

LanProbe Operation  
Restarting the Probe  
Cycling Power  
A power outage or cycling power to LanProbe causes a warm start. LanProbe  
does not have a power switch; therefore, cycling the power consists of  
disconnecting and reconnecting the power cord.  
Use the following procedure to warm start the probe using LanProbe’s Main  
Menu:  
1. Connect a local terminal (or a PC emulating a terminal) to LanProbe. Refer  
to Chapter 2 “Local Terminal Configuration” for information on connecting  
a local terminal.  
2. Press the CONFIG button once (on the back of the probe) to place LanProbe  
into the configuration mode. Use a narrow, pointed object (like a pen) to  
press the recessed CONFIG button. LanProbe then displays its Main Menu  
on the terminal. Figure 5-18 shows LanProbe’s Main Menu.

Verify the following before you start the download procedure.  
The probe is connected to the network.  
The IP address, subnet mask, and default gateway of LanProbe are  
configured correctly.  
A terminal (or a PC running terminal emulator software) is attached to the  
probe’s RS-232 port (using a null modem cable). Configure the  
communication link for 8 bits per character, 1 stop bit, no parity, Xon/Xoff  
handshaking, and a baud rate of 9600.  
You will also need the IP address of the networked PC.  
Use the following procedure to download firmware to LanProbe from the  
networked PC using a terminal:

After the download process is complete, LanProbe reboots and starts running the  
new firmware.  
If an error occurs during the download process, LanProbe returns to the Main  
Menu without storing the new firmware to memory.  
If you are using an HP workstation and LanProbe takes more than 90 seconds to  
download new firmware and to restart (boot), verify that the workstation is setup  
correctly, and restart inetdby entering and running the following commands at  
the workstation:  
ps -ef | grep inetd  
/etc/inetd -k  
/etc/inetd  
NOTE  
If you are experiencing tftp transfer timeouts or read errors, use the following  
procedure to verify that tftp is configured correctly on your unix workstation.  
1. Verify tftpd functionality by copying the firmware file to another directory  
using the tftp command.  
a. cd/tmp  
b. tftp 127.0.0.1  
c. get ethsnmp.lp  
d. quit  
2. If the previous step fails, the problem is due to the tftpd configuration on the  
unix server.

The memory allocated to each parameter depends on how much memory is  
installed in LanProbe. The memory parameter values relate to the various items in  
the RMON or the Agilent private MIBs. These parameters were valid at the time  
of publication.  
Table B-7 on page 103 shows the memory allocated to each parameter for the  
available LanProbe memory configurations. The memory allocation shown for  
each table assumes that all of the available memory within the probe is allocated  
to the identified table.

LanProbe Specifications  
NOTE  
The parameter values shown in Table B-7 on page 103 are approximate and  
subject to change without notice. The values assume that RMON-2 tables  
have not been created.  
Host Table entries, Matrix Table entries, TopN entries, History buckets and  
Trace buffers (packet capture buffers) are allocated dynamically from the  
same memory allocation. The values shown for History buckets assume  
that no Trace buffers are configured. If Trace buffers are configured, the  
number of History buckets are reduced. The value for host and matrix table  
sizes assume that both tables are the same size.  
The value shown for Trace buffer octet capacity assumes that only the  
default history studies are set up.

Glossary  
10Base-T  
10 Mbps, BASEband operation, unshielded Twisted-pair wiring used for Ethernet  
networks.  
Agent  
A node (or software/hardware on a node) that supplies network management  
information.  
Battery-backed RAM  
The probe’s memory that contains a copy of the probe configuration. If power is  
removed from the probe (either by unplugging the power cord or from a power  
outage), this memory is preserved by power provided by the probe's internal  
battery.  
Bridge  
A device providing an intelligent connection between two otherwise independent  
LANs. Bridges operate at layer 2 of the ISO OSI reference model. A bridge  
inspects every packet originating on either LAN and creates a table of nodes and  
their locations. It isolates the LANs from each other, allowing both sides to pass  
traffic internally. If a transmission from one LAN is addressed to a node on the  
other LAN, the bridge transmits it onto the other LAN for the destination node.  
Broadcast address  
The station address FFFFFF-FFFFFF. Packets intended for all nodes on a LAN  
use this address as the destination address.  
Broadcast packet  
A packet sent to all nodes on a LAN.  
Collision  
The result of two or more nodes on a LAN transmitting at the same time,  
producing a garbled transmission.  
Console  
The ASCII terminal, or PC emulating an ASCII terminal that is connected to the  
probe and used to configure, monitor, and troubleshoot the probe.

CRC (cyclic redundancy check)  
An error detection scheme used by the probe to ensure that packets received by  
the probe have not been corrupted during transmission from the source node.  
CSMA/CD (Carrier Sense Multiple Access/Collision Detection)  
The network access-control mechanism that is based on collisions and utilized by  
Ethernet networks. On contention-based networks, like Ethernet networks, each  
station must detect an idle network prior to transmitting. If more than one station  
transmits simultaneously, a collision occurs, all stations are notified, and the  
colliding stations try retransmitting after waiting a random amount of time.  
Default Gateway Address  
The address of the gateway which is closest to the probe.  
DRAM  
Dynamic Random Access Memory, which is the main memory of LanProbe.  
Ethernet  
A LAN developed by Xerox Corp., Digital Equipment Corp., and Intel Corp. It  
uses the CSMA/CD method of access and transmits at 10 Mbit/s on a bus  
topology. The IEEE 802.3 standard evolved from Ethernet, but they are not  
exactly the same. Network devices based on both standards can co-exist on the  
same medium, but they cannot exchange data directly without special,  
“bilingual”, software that can decode packets of both types.  
Extended LAN  
A network consisting of two or more LANs that are connected by bridges, routers,  
or other similar devices. Resources on the LANs can be accessed by users on any  
of the LANs. See also LAN.  
Flash EPROM  
EPROM that can be erased and reprogrammed while installed in a circuit.  
Gateway  
A dedicated computer that is used to route frames from one dissimilar network to  
another.

IEEE 802.3 standard  
Part of the Institute of Electrical and Electronics Engineers 802 family of LAN  
standards. The 802.3 standard defines the physical layer (layer 1) and part of the  
data link layer (layer 2) of the ISO OSI reference model for a CSMA/CD LAN.  
The IEEE 802.3 standard evolved from Ethernet, but the two networks are not  
fully compatible with each other.  
IP Address (Internet Protocol Address)  
A 32-bit address that is divided into network-identifier and host-identifier fields,  
which are used to identify a particular physical network or a particular device  
attached to that physical network (respectively).  
LAN (local area network)  
A general-purpose communications network that interconnects a variety of  
devices within a limited geographical area. Two common LANs, IEEE 802.3 and  
Ethernet, have compatible cabling requirements, and can co-exist on a common  
installation, but have different protocols.A LAN might connect computers on  
adjacent desks, within a building, or within several buildings of a campus. See  
also extended LAN.  
LAN cable  
The medium through which data moves in a LAN. LAN cables come in many  
types. For example, thick (10 mm) coaxial cable, thin (5 mm) coaxial cable, fiber-  
optic cable, and twisted-pair cable.  
LanProbe  
See probe.  
MAC address  
A 12-digit (48 bit) hexadecimal number that identifies a specific network station  
and allows messages to be directed to that station only. Because the IEEE has  
assigned identifiers for each hardware manufacturer, no two pieces of equipment  
have the same address. The address assigned according to the IEEE plan is  
referred to as a device’s globally-administered station address. Some devices  
provide an option for the user to assign a different station address that will  
override the original. This type of address is referred to as a locally-administered  
station address. The station address is also commonly called a MAC address,  
Ethernet address, Token-Ring address, or physical address.

Manager  
A node that collects network management information from agents.  
Management station  
A station that collects network management information from probes.  
MAU (Medium Attachment Unit)  
The assembly used to provide the physical connection and access to a LAN. It is  
the device on the LAN that detects collisions. (A transceiver is also called a MAU  
in the IEEE 802.3 standard.)  
MIB (Management Information Base)  
A data structure used for communication and control of the probe.  
NetMetrix  
NetMetrix refers to the HP OpenView NetMetrix/UX software suite for HP-UX  
and Solaris.  
Node  
A computer or other addressable device on a network, including PCs, terminals,  
probes, routers, and mainframes. Usually, a node has a station address.  
Object  
Any device that can be monitored or controlled by use of the SNMP protocol.  
Packet  
A bit stream consisting of predefined fields that contain data, addresses, and  
control information. In the IEEE 802.3 environment, this structure is often  
referred to as the MAC frame. Packet is used in the Ethernet environment and is  
used in this guide because it is the more commonly understood term. Different  
protocols have different packet and frame specifications.  
Private MIB  
A proprietary MIB that has variables which are used for probe configuration and  
control options.  
113

Probe  
A device on the LAN that monitors all frames and produces network management  
information including current and historical traffic statistics and snapshots of  
selected frames. Probes are also known as monitors.  
Protocol  
A set of rules that governs data transfer among devices on a network. A protocol  
identifies the handshake type, frame size and format, timing, error recovery  
scheme, word size or other characteristics of each transfer, depending on the  
system.  
RMON MIB (Remote Network Monitoring MIB)  
The collection of objects defined by the Internet Engineering Task Force in RFC  
1757, RFC 1213, RFC 1157, RFC 2021, RFC 2074, and Agilent LanProbe private  
MIB that are used for network monitoring.  
RS-232 port  
A serial interface connector on a computer or peripheral that adheres to the current  
RS-232 standard. The LanProbe RS-232 port adheres to this standard.  
SAM (System Administration Manager)  
A configuration tool provided by HP-UX for managing system resources and  
changing configuration parameters.  
Server

Station  
A computer or other addressable device on a network, including PCs, terminals,  
probes, routers, and mainframes. A station must have an IP address.  
Subnet Mask  
Identifies the subnet field of a network address and is a 32-bit Internet address  
written in dotted-decimal notation. A subnet mask is used to divide a network  
into sub networks.  
Terminal  
An input/output device that permits interaction with a probe or computer. The  
device can be a display and keyboard, or a personal computer. An ASCII  
terminal, or PC emulating an ASCII terminal, can be connected to the probe for  
configuration, monitoring, and troubleshooting the probe.  
Topology  
The organization of network devices in a network. Ethernet uses a bus Topology.
