Network
Man agement
Full Network View
from a Single PC
Many businesses today run their computers on a computer network.
Using a network man ag ement solution allows you to track the
performance of your network and quickly identify problems before they
affect your users. This in turn helps you to run your business more
efficiently .
Network management provides the following benefits:
Full Network View from a Single PC
■
Reduci ng Downtime
■
Improving Performance
■
Freeing Up Personnel
■
Reduci ng Equipment Costs
■
Some network management software (including 3Com
Supervisor) allows you to view and display all devices, links and activity o n
your network from the convenience of a single, centrally-situated PC. For
example, you can easily locate and monitor the health of a specific PC or
other type of device without leaving your desk.

Reducing Downtime Network downtime can affect your business and its productivity. When
this happens, it is important that you restore connections as quickly as
possible.
Reactive network management does reduce downtime by responding to
device and link failures. However , a network management solution
provides you with a proactive management capability. This reduces the
number and severity of failures and can help avoid dow ntim e altogether.
Improving
Performa nce
Network topology and monitoring information give you an accurate view
of your network’s struct ur e and traff i c rates . Using this information you
can make changes to the structure of your netw ork to im pr ove its
performance.
Freeing Up Perso nnel Using a network management solution which gives a full view of your
network and actively warns you of problems, reduces the day-to-day
demands on person nel to find and fix problems. This automation allows
people to focus on key management activities.
Reducing Equipment
Costs
Network manag em ent ena bles you to make better use of current
equipment, delaying expensive and disr uptive upgrades until they are
necessary . Understanding your network also enables you to choose
upgrades that give the best return for any investment.
Key Ne two r k Man agement Functions

Major Benefits of Network Management with Netwo rk Superviso r
Color-Code d View of
Your Network
Connectivity
Wizards are provided to guide you through the setup and configuration
of Network Supervisor parameters.
The Wizards often suggest useful default settings which can help you
start monitoring your network even when you are not sure which values
to set.
Networ k Supe rvisor b rings yo u the follow ing major benefits to help you
manage your network. These are:
Color-Coded View of Your Network Connectivity

Real-Time Detailed Stress Monitoring
■
Total V isib ili ty of Ne t w o rk A ct iv ity
■
Immediate No tif ication of P r ob l e m s
■
Using Network Supervisor’s graphical m ap a nd int ell ig en t m onitoring you
can quickly identify problem areas and overloaded links on your network.
The map shows the devices and connections on your network, including
the links attaching the hubs, switches and routers to PCs. This provides an
instant, color-co ded view of the state of your network.
Real-Time Detailed
Stress Monitoring
Network Supervisor’s map also provides physical connectivity information
for your network.
Good m onitoring involves examining a combination of available
bandwidth, gen erated erro rs, service availabilit y and service re s pon se
times.
Using Network Supervisor’s monitoring and alerts system, you are free to
run your business, while Ne twork Supervisor w atches the important parts
of your network and informs you if anything goes wrong.
Stress monitoring pro vides yo u with a p erform anc e m easures of a
network object (a device or link) against pre-defined thresholds.
Network devices such as switches are monitored for their own internal
performance and for their external communication performance with
other devices. End stations are monitored for response time and service
availability.
Settin g up Ne two rk Supervisor for the First Time 13

Netwo rk Activity
Immediate
Notification of
Problems
Setting up Network Super vi sor fo r the First T ime
You cannot always be scanning the Net work Supervisor map for potential
problems. You need another way of achieving total visibility of your
network.
Network Supervisor pr ovides this with an Event List which logs all issues
as they occur.
Network Supervisor’s Event List also lets you annotate events, adding
additional information or comments on how the problem was solved.
This allows you to build a knowledgebase of your network, making
recurring problems easier to identify and resolve.
You also need to be confident that you will know of network problems
befo r e o r at th e s am e tim e as y our users.
Network Supervisor pro vides an alert system which ensures that you are
notified of problems immediately . You can choose various visual and
audible methods to notify you of significant network activity , for example,
an e-mail, sound or popup dialog box.
These are the initial ste ps which provide the co nt e xt for your network
management:

There are two steps w hich are u sed to construct a map of you r network.
Network Supervisor:
1 Finds the devices connected to your network (and builds a model of each
one)
A ping m essag e is sent by Netw ork Supervisor to each IP address in the
range y o u c h oo s e t o s pec if y. Each device that r esponds is then contacted
individually and Network Supervisor constructs a model of that device
from the information it provides.
2 Figures out how each device is connected to the rest of your network
Net wor k Sup ervis or wo rks o ut th e con nec tion s by ta lking to th e sw itch es,
routers and hubs on your network.
Monitoring Cor e
Devices and Links
Network Superv iso r at tempts to id e ntif y the c o re d evices and links and
monitor them for you. It judges which devices and links are most
important to keep your network’s central services operating; that is, the
backbone devices of your network. This is your core network.
For your initial settings, it is probably best to m onitor only these devices
which are critical to your network’s operation and performance levels.
Network Supervisor also sho ws t he state of each core l ink. F or example, it
shows whether each core link is up or down. Network Supervisor uses
color-coding to enable easy recognition of the stress level on each device
and link.
If there is not enough information for Network Supervisor to discover
what connections are present on a part of the network, it displays a cloud
where it knows that devices are connected but cannot say how.
Unsupported SNMP devices (for example, some non-3Com devices) are
shown in this way.
Monitoring Add itional Devices and Links
You can also manually start monitoring any other devices or links which
are particularly important to your network.
For example, you may have a switch which connec ts a server farm. As this
switch and its links are important to many users, you may want to turn on
monitoring to it and other links like it.
A server farm is a collection of servers (for example, file servers and
printers) which are available to groups of users on a network.
Viewing the Stress on your Network 15
Reacting to Netwo rk
Events
When you start monitoring for the first ti me, you m ay start to see many
events in the Event List.
If the number of events in the list appears to be excessive, this may
indicate that the activity thresholds set are too low for your network. If
this is the case, Network Supervisor lets you tune the thresholds to a
more app r opriate level.
You should decide which of thes e events are important and tell Network
Supervisor how to handle these when they occur again.
For e x a mple, you m a y c h oo s e t o co nf ig ure an alert for a par tic ular event:
this m ea ns that ever y ti m e t he sa me pro blem occu rs again, you will
immediately be informed of it. This is a reactive step which you will only
need to do once.
Alerts are a notification mechanism. They can be an e-mail, sound, popup
message or can launch an application. They are attached to an item on
your network map and are triggered when an event occurs.
Once you have configured your first set of alerts, you can then use the
following steps to quickly locate and identify any problems on your
network:
1 React to an alert.
Viewing the Stres s on your Network
2 Look in the Event List.
3 Follow the link from the Event List to the problem area on the map.
4 Perform diagnosis.
When you launch a Network Stress window (shown in Figure 1), Networ k
Supervisor shows the magnitude of stres s for a particula r device. This
provides yo u with more use f ul information than merely being told the
device has a high or low level of stress.
Stress is the performance measure of a network object (a device or link)
against pre-defined thr esholds.
The s tress bars r e p r e s ent the s t r e s s of th e devices and links on your
network by low (green), warning (yellow) and high ( r ed) zones.
16 C
HAPTER
SING NETWOR K SUPERVISOR TO MANAGE YOUR NETWOR K
2: U
The significant advantage of having a yellow (warning) zone is that it
gives you a cl ear indication that a monitor is approaching a serious
condition. This may allow you to predict some network problems before
they become critical.
For example , a half-lit green bar indicates that you should have
consider able scope before that device requires attention, while a fully-lit
red bar shows that something is seriously wrong with the performance of
that device and that it probably needs urgent attention.
A monitor is a meas ure of the stress being expe rienced by a networ k
devic e or l ink.

Once Network Supervisor has identified whic h device or link is causing a
problem, you may want more detailed inform ation on the indivi dual

Managing and Mani pulating Events 19
Managing and Manipulating Events
Intelligent Eve nt
Generation
The Network Supervisor Event List greatly improves your ability to
prioritize and react to problems on your network.
Network Supervisor generates events intelligently. For example, to
prevent utilization ‘spikes’ causing unnecessary events, the threshold set
must be exceeded for a reasonable period of time (determined by
Network Supervisor) before an event is generated.
This means that Network Supervisor will produce a more accurate
representation of what is effectively one incident, than if it generated an
event every time the threshold w as passed.
The events in the Event List are generated internally by Network
Supervisor, they are not SNMP traps generated by network devices.
Network Supervisor provides the following to help you manage
genera ted events:

about why an event occurred previously and a suggested solution.
You can then filter events based on the content of a comment, searching
for information to help solve a newly discovered problem.

problems quickly.
Sorting
Sorting lets you order events by the column headings of the Event List.
For example, you can sort by event severity, time or importance.
Acknowledg ing
This lets you mark as acknow ledged, even ts or gr oup s of events which
you have seen.
Ageing
This lets you control how many events are retained in the Event List. You
can se t a m a x im um numbe r o f ev en ts to be k e pt or s p ec ify that event s of
a certain age (number of days) are deleted.
Instant Notification of Significant Activity Using Alerts
Although the Event List gives you a comprehensive view of network
activity, it is also useful to find out instantly if there is any significant
activity on your network.
Network Supervisor pr ovides alerts for this purpose. They instantly notify
you of signific ant network activity without requiring that you
continuously have Network Supervisor as the active application on your
PC.
If yo u w a nt to be n otifi e d of an ev en t as s oo n as i t h a p pen s , c o nf i g ure an

message, audio alert, pager message or it can launch a specified
application.

Tracking the Devices
on Your Network
Sometimes it is he l p f u l to ha v e a n o verview or s t ati s ti c al s u mmary of
certain aspects of your network.
This type of information is useful for outlining patterns and trends in the
use of your network which may not be easily visible in o ther views. It is
especially useful for strategy and planning purposes, such as the future
expansion of your network when your business, volume of network
traffic and numb er o f us ers expa nd .
Reports can be generated for all devices on your network map or on
selecte d de vices only.
You can use the Network Inventory Report (shown in Figure 4
) to help
track the number of PCs and other devices currently on your network.
This is particularly useful for asset management. For example, at the end
of a financial month or year, this type of information can help you
calcula te and budget for the follo win g y ear’s requirements.

Planning Your
Network Capacity
Listing All th e D ev ices
Attached to Each Port
You can use the Network Capacity Report to calculate the number of
ports available on your network and identify which devices they belong
to.
This provides a powerful planning tool which allows you to quickly view
the devices which are close to using the maxim um num ber of ava ilable
ports. Using this information, you can then plan the number of ports that
your network needs for the future.
For example, you can calculate the maximum number of ports that each
device on your network can support. As your business grows, use a

You can then plan when you should start to invest in new devices, before
the capacity is reached and the state of your network b ecomes critical.
The Network Topology Report lets you list and identify what devices and
types of device are attached to each port. It gives you a printable list of
devices and their connectivity status. This makes it especially useful if you
have to go into a wiring closet to modify a device or if you do not have a
portable PC.
The list of devices includes a textual description of each attached device.
Network Discovery
Report
The Network Discovery Report outlines which of the discovered
suppor t ed devices have unsupport ed agents inst alled .
It also provides details of which version of agent software is installed on a
device and which version of agent software is the earliest supported by
Network Supervisor for that type of device.
