The Ethernet LanProbe has 16 MB of memory (optionally 32 MB), and uses
FLASH EPROM. Future upgrades to La nProbe’s firmware are easily do wnloaded
over the LAN to multiple probes simultaneously. You can also download
firmware using LanProbe’s serial port.
LanProbe maintains a variety of statisti cal 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 -Ban d connection to the pr obe ca n 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 netw or k manag er t o select one or several no des t o pe rf orm 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 connectiv ity from each point . When a node becomes unr eachable an aler t
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
Installation and Configuration Overview
Installation and Configuration Overview
To quickly install and configure your LanProbe, it is important for you to
understand the available configuration and installation options. Configuration
consists of setting the LanProbe parameters (IP address, for example). Installation
consists of physically installing the probe and connecting it to the network.
You will reference different chapters of this Installation/User’s Guide depending
on which of the following installation and configuration options you select:

“Installation and Bootp Server Configuration” below
Local Terminal Configuration and Installation
This method of installation and configuration requires that you configure the
probe first and then install the probe. These procedures are detailed in Chapter 2
“Local Terminal Configuration” and Chapter 3 “Installation”.
Installation and Bootp Server Configuration
This method of installation and configuration requires that you install the probe
first and then configure the probe. These procedures are detailed in Chapter 3
“Installation” and in Chapter 4 “Bootp Server Configuration”.

Introduction
LanProbe Overview
This section provides some general information on the Agilent 4986B Ethernet
LanProbe.
The LanProbe is a non-intrusive SNMP agent that monitors all packets and
network performance. This includes current and historical traffic statistics and
snapshots of selected packets.

System Overview
A typical LanProbe distributed monitoring system consists of the following:
z
One or more LanProbes
z
One or more NetMetrix management stations, using NetMetrix

The LanProbe implements groups 1 through 9 of RFC 1757 and groups 11
through 20 of RFC 2021. Refer to RFC 1757 for more informati on on the Remo te
Network Monitoring Manage ment Inf ormati on Base Pr otocol I dentif iers (RMON1 MIB), to RFC 2021 for information on the RMON-2 MIB, and to RFC 2074 for
information on Protocol Identifiers. LanProbe also supports MIB-II.

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 docu mentation fo r more information.
Access Security
The LanProbe configuration menu allows network administrators to disable
standard RMON functions which c ould be consi dered a se curity risk . The securit y
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.

LanProbe Overview
Introduction
The LanProbe private MIB uses a four-level access control scheme. An access
level is assigned for each communi ty stri ng to be used with Lan Probe. The acc ess
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.
