Introduction 1 - 1
RMON Overview
Remote Monitoring (RMON) is a standards-based network management
tool that allows you to efficiently and effectively monitor segments
throughout the network. You can use RMON to identify and isolate
potential problems in your network before disruptions occur.
RMON-compliant devices operate without impacting network operation.
They function as promiscuous devices, which listen to and capture data on
the network, but do not add additional traffic.
The following sections describe:
❑
RMON Architecture
❑
Ethernet RMON Groups
RMON Architecture
RMON technology requires two components within a network:
❑
RMON Probe
❑
RMON Client
RMON Probe
An RMON probe contains both hardware and software, and is referred to
as the RMON agent. As a promiscuous device, the RMON probe:
❑
Observes packets on the network
❑
Captures packets that match user-defined criteria
❑
Stores packets from the network segment
Through the packet capture and store feature, the RMON agent provides
an extensive set of Ethernet-based statistics to the network manager.
1 - 2 Ethernet RMON MultiProbe Module Installation and Operation Guide
RMON Client
The RMON Client consists of a management station running an application
that uses SNMP (such as the 3Com ONdemand LANsentry™ software) to
request data from the probe and display that data in various formats. You
can also use the graphical interface to configure the RMON agent.
The client application does not have to be located on the same segments as
the network to which the probe is assigned, but does need connectivity to
the networks.
Ethernet RMON Groups
The Ethernet RMON standard is defined in Request For Comment (RFC)
1757 (formerly 1271). The goal of the standard is to ensure interoperability
in multivendor environments. As defined by the RFC standards for Ethernet
RMON, the Ethernet RMON specification identifies the following RMON
groups:
❑
Alarm Group - Allows you to define and set thresholds for various
counters. If a counter reaches a predefined threshold, an event is
generated. (See Event Group below.)
❑
Event Group - Controls the action taken as a result of an event, (an
event can be triggered by an alarm). For example, if a counter
reaches a threshold, then a trap may be generated or an event may
be logged.
❑
Filter Group - Instructs the RMON MultiProbe Module to capture
only those packets that match a specific criteria (such as IP Protocol
or a specific MAC address).
❑
History Group - Provides historical views of statistics based on
predefined sampling intervals. This information illustrates traffic or
error patterns, which can be useful in trend analysis.
❑
Host Group - Contains statistical counters, grouped by MAC address,
specific to each station on the network. This group also contains the
order in which devices or stations were discovered.
Introduction 1 - 3
❑
HostTopN Group - Sorts stations by top traffic contributors. You can
use this information to identify the most active hosts on a segment or
the hosts producing the most errors.
❑
Matrix Group - Collects statistics between pairs of devices on the
network and tracks information specific to each connection, such as
the number of packets transmitted between devices.
❑
Packet Capture Group - Handles the capture and uploading of
packets collected by the RMON MultiProbe Module.
❑
Statistics Group - Contains cumulative traffic and error statistics (for
example, packet distribution, and Cyclic Redundancy Check) for each
device being monitored.
1 - 4 Ethernet RMON MultiProbe Module Installation and Operation Guide
RMON MultiProbe Module Overview
The RMON MultiProbe Module is a single-slot Ethernet module that you
install in an ONline and ONcore hub. The RMON MultiProbe Module can
monitor up to three Ethernet networks simultaneously and perform all
functions on all networks in parallel.
The RMON MultiProbe Module supports:
❑
UDP/IP (User Datagram Protocol/Internet Protocol) over Ethernet
❑
SLIP (Serial Line Internet Protocol)
❑
SNMP (Simple Network Management Protocol) over UDP for
management access
❑
ICMP (Internet Control Message Protocol) Echo and Redirect
Introduction 1 - 5
RMON MultiProbe Module Features
When you use the RMON MultiProbe Module in conjunction with an RMON
client application, you can:
❑
Monitor the network
❑
Generate reports based on network information
❑
Filter and capture packets
❑
Process events and thresholds
❑
Detect network events
In addition, the RMON MultiProbe Module monitors:
❑
Per-network collisions
❑
Per-port collisions (PPC)
❑
Port-address correlation (PAC)
1 - 6 Ethernet RMON MultiProbe Module Installation and Operation Guide
Other benefits of the RMON MultiProbe Module include:
❑
3Com TriChannel™ Architecture - The RMON MultiProbe Module
operates in an ONline System Concentrator and an ONcore Switching
Hub.
❑
Slot Independence - You can install modules into any available slot
in a 3Com ONline or ONcore hub. This flexibility eliminates the need
to shut down the network and rearrange the existing configuration
of the concentrator when you install new modules.
❑
Hot Swap Capability - You can install or remove modules from the
ONline or ONcore hubs when the hub is powered up without
affecting the operation of any other modules in the concentrator.
❑
Management Support - You can manage the RMON MultiProbe
Module through the 3Com® ONdemand LANsentry application. You
can also manage the module using terminal management through an
ONline Ethernet Management Module (EMM) or an ONcore
Distributed Management Module (DMM).
❑
Compliance - The 3Com Ethernet RMON MultiProbe Module
complies with the RMON standard as defined by RFC 1757.
Introduction 1 - 7
Theory of Operation
This section describes the theory of operation for the RMON MultiProbe
Module.
The RMON MultiProbe Module:
❑
Supports simultaneous analysis of three Ethernet channels
❑
Monitors the network proactively
For example, when a network event occurs or a problem becomes
apparent in the network, you use a protocol analyzer to attempt to isolate
and correct the problem. RMON technology also provides you with
protocol analyzer capabilities. However, RMON takes a more proactive
approach to network monitoring by:
❑
Alerting you of network events before they can become a problem
❑
Providing you with information to help isolate problems
You can also configure the RMON MultiProbe Module to check
continuously for specific error conditions and notify you or log the event
when the conditions occur.

This section describes the format of the modem:
❑
Init Strings
❑
Hangup Strings
To allow the RMON MultiProbe Module to communicate with a modem or
a serial data switch, use the modem Init String and Hangup String. The
strings contain embedded commands to control how the module interacts
with a remote device through the serial interface. Commands are
represented as 2-character sequences beginning with the ^ character.
Table 3-5 describes the modem Init Strings and Hangup Strings that the
RMON MultiProbe Module supports.
Note: Command characters are case-sensitive.

^s
Sends string that follows, which is terminated by the
next command or the end of string.
^c
Delays for the number of seconds that follows. Discard
any data received instead of storing it in a buffer for
parsing.
^t
Sets timeout to the value represented by the decimal
digits that follow. The default timeout is 20 seconds. The
timeout may be overridden by a smaller serial Timeout
configured for the associated serial interface.

^w
Waits for the reply string that follows which is
terminated by the next command or the end of string.
Partial and case insensitive matching is applied (that is, if
the RMON MultiProbe Module finds the reply string [any
case combination] anywhere in the received string, the
match is found). If the current timeout elapses without a
match, the module ignores the remaining control string.
^!
The ^ character.
^d
Delays the number of seconds specified by the decimal

You may also insert binary data into the data stream using the following
control sequence for each byte of binary data: ^0x## (where ## is the
hexadecimal representation of the data byte).
Two ASCII characters (0-9, a-f, A-F) must follow the ^0x control prefix. For
example, ^0x0D^0x0A is interpreted as a carriage return followed by a line
feed.
Modem Response Strings
This section describes the modem response string formats:
❑
Connect Response Strings
❑
No Connect Response Strings
Connect Response - An ASCII string that contains substrings that describe
the expected modem connection response code and associated bps rate.
The substrings are delimited by the first character in the string.
The following connect response string example is interpreted in Table 3-6.
CONNECT/300/CONNECT 1200/1200/CONNECT

The RMON MultiProbe Module uses the information in this string to adjust
the bps rate of the serial interface once you establish a modem connection.
No Connect Response - An ASCII string that contains response codes
generated by a modem to report the reason for a connection attempt
failure. The response codes are delimited by the first character in the string.
For example:
/NO CARRIER /BUSY/NO DIALTONE/NO ANSWER/ERROR/
If the RMON MultiProbe Module receives one of the response codes on its

Configuring the Module and Interfaces
Before the RMON MultiProbe Module can become operational, you must
configure the following parameters for the module and interfaces:
❑
IP address (for each interface)
❑
Subnet mask (for each interface)
❑
Default gateway (for the module)
Assigning the Interface IP Address and Subnet Mask
You must assign a unique IP network address for each interface.
For example, if you do not bridge the three interfaces, you could assign IP
addresses for a subnetted class B network as shown in the following IP
address examples:
Note: In both of the IP address examples, each interface has a
subnet mask of 255.255.255.0.
❑
Interface 1 - 151.104.36.7
❑
Interface 2 - 151.104.37.8
❑
Interface 3 - 151.104.38.9
For example, if you bridge the three interfaces, the network portion of the
IP addresses can be identical as shown in the following IP address
examples:
❑
Interface 1 - 151.104.36.7
❑
Interface 2 - 151.104.36.8
❑
Interface 3 - 151.104.36.9

Using BOOTP to Configure the Module and Interfaces
This section describes:
❑
BOOTP Description
❑
BOOTP Configuration Process
❑
BOOTP Requirements
❑
Using BOOTP
BOOTP Description
BOOTP (Bootstrap Protocol) is a UDP/IP-based (User Datagram
Protocol/Internet Protocol) broadcast protocol which allows a device to
configure itself dynamically without user intervention. Use BOOTP to
download configuration information from a BOOTP server to the RMON
MultiProbe Module interface configured for BOOTP.
BOOTP Configuration Process
During initialization, the RMON MultiProbe Module verifies that the IP
address and subnet mask of the interface configured for BOOTP is not set
to null (all zeros). If either the IP address or subnet mask are null, the
module automatically sends out BOOTP requests every 60 seconds through
the designated BOOTP interface until it receives a valid BOOTP response. If
the default gateway is originally set to null, the BOOTP server also supplies
the module with gateway information.
The response from the BOOTP server supplies the RMON MultiProbe
Module with its network parameters. When BOOTP obtains valid addresses,
the module stores the parameters in battery-backed RAM and becomes
operational.
The RMON MultiProbe Module defaults to interface 1 for a BOOTP server.
Because only one interface at a time can be used with BOOTP, you can only
download configuration information to the interface configured for BOOTP.
Configuring the Module 3 - 29
To configure other interfaces, use the Modify/View Network Settings
configuration menu to change the BOOTP network interface.
BOOTP Requirements
The BOOTP server must perform the following functions:
❑
Map hardware addresses to IP addresses
❑
Respond to BOOTP requests from clients
❑
Support the vendor-specific subnet mask and default gateway fields
Using BOOTP
To use BOOTP, add the following information to the BOOTP server
bootptab configuration file:
❑
MAC address - Hardware address of the RMON MultiProbe Module
interface to be configured
❑
IP address - IP address for the module interface
❑
Subnet mask - Subnet mask for the module interface
❑
Default gateway - Default gateway for the RMON MultiProbe
Module
For additional information on BOOTP configurations, refer to your server
documentation.
Sample BOOTPtab file
A sample bootptab file is shown on the next page. If necessary, create this
file on the BOOTP server.

Assigning Interfaces to Networks
To assign RMON MultiProbe Module interfaces to networks, you can use
either:
❑
DIP switch settings, if your hub is unmanaged (an ONline or ONcore
management module is not installed in the hub).
❑
ONline or ONcore network management commands (if an ONline or
ONcore management module is installed in the hub).
You can assign the three RMON MultiProbe Module network interfaces as
follows:
❑
Interface 1 to Ethernet 1 or Isolated
❑
Interface 2 to Ethernet 2 or Isolated
❑
Interface 3 to Ethernet 3 or Isolated
Note: Each interface can only be configured to its corresponding
Ethernet network or isolated (that is, Interface 1 to
Ethernet 1, Interface 2 to Ethernet 2, Interface 3 to
Ethernet 3).
3 - 32 Ethernet RMON MultiProbe Module Installation and Operation Guide
Using the DIP Switch to Assign Networks
If you have an unmanaged hub, use the DIP switch on the module to assign
networks to the RMON MultiProbe Module interfaces. However, the DIP
switch settings are ignored if the following two conditions are met:
❑
A network management module is installed in the hub.
❑
The master management module has DIP_CONFIGURATION disabled.
The RMON MultiProbe Module contains an 8-position DIP switch (SW1).
This DIP switch allows you to configure and enable the three RMON
MultiProbe Module interfaces to the corresponding Ethernet networks.
Figure 3-8 shows the DIP switch location on the module

Using Management Commands to Assign Interfaces to
Networks
With a terminal attached to a 3Com management module console, you can
use management commands to assign the RMON MultiProbe Module
interfaces to networks.
The following 3Com network management modules enable you to assign
interfaces to networks:
❑
ONline Ethernet Management Module (EMM) (Version V4.20)
❑
ONcore Distributed Management Module (DMM) (Version V2.10)
To configure all other RMON MultiProbe Module parameters (such as
IP address, subnet mask, and serial configurations), use the RMON
MultiProbe Module configuration menus.
Examples of the management commands for assigning networks are
discussed here briefly. For additional information on management
commands, refer to the appropriate management module commands
guide.
Note: Management commands that refer to ports are applicable
to the RMON MultiProbe Module interfaces. (For example,
the SET PORT and SHOW MOD ULE_PORT commands apply
to the module interfaces.)
Configuring the Module 3 - 35
Management Command Examples
To assign interface 1 on the RMON MultiProbe Module in slot 7 to
Ethernet 1, use the following network management command:
SET PORT 7.1 NETWORK ETHERNET_1
Port 07.01 network id set to ETHERNET_1.
To assign interface 1 to isolated, use the following command:
SET PORT 7.1 NETWORK ISOLATED
Port 07.01 network id set to ISOLATED.
To assign interface 3 on the RMON MultiProbe Module in slot 7 to
Ethernet 3, use the following network management command:
SET PORT 7.3 NETWORK ETHERNET_3
Port 07.03 network id set to ETHERNET_3.
You cannot assign an interface to a network other than its corresponding
network. For example, a management module aborts the following
command:
SET PORT 7.3 NETWORK ETHERNET_1
Port 3 can only be set to ETHERNET_3 or
ISOLATED: command aborted.
