Set up Network Discovery | 95 CHAPTER 8 Set up Ne tw or k Di sc o v er y The following flowchart shows all the im portant tasks that must be completed to set up Network Discovery.
96 | Set up Network Discovery Network Discovery Import ant: If you are usi ng Network Discover y with Desk top Inventory, you must follow th e steps outlined i n Using Network Discovery with Desktop Inventory and Desk top Administration . How it w orks Essentially, network configura tion works as follows.
Set up the IPv4 range(s) to discover | 97 Setup Guide Note: The list of comm unity stri ngs must be separated by co mmas (for example, “public,private,string1,string2”). 3 Click Change . Note: Hop 0 (zero) is always the Peregrine appliance itself, an d hop 1 is always the default gateway.
98 | Set up Network Discovery Network Discovery Impor t y our IPv4 ranges from a CSV file Instead of entering all your IP ranges manually, you ca n i m p o r t t h e m f r o m a C S V file.
Set up the IPv4 range(s) to discover | 99 Setup Guide Groups/Sets in the CSV file, and you do not select a default, the IP range will not be imported. 5 Click Import . Once you import the CSV file, you will see a report explaining whether or not the import was successful.
100 | Set up Network Discover y Network Discovery To delete an IPv4 range 1 From Administration > Network configuration > List IPv4 ranges . 2 Select the IPv4 range. If the range has subranges, Network Discovery gives you a ch oice of deleting only the range or of deleting the range plus all of its subranges.
Set up the IPv4 range(s) to avoid | 101 Setup Guide 3 For Property Set/Group , select Network: Active Discovery . Network Discovery will perform netwo rk discovery (pi ng, poll, and table read) on the rang e you have entered. 4 Click Submit . Repeat step 1 to step 4, if ne cessary, for all your subnets.
102 | Set up Network Discover y Network Discovery Add ranges for DHCP ser v ers and unmanaged routers If you have one or more DHCP servers or you have unmanaged routers, add their IPv4 addresses and apply the appropriate Property Group so that Network Discovery will monitor th e ranges differently.
Add community strings—the quick way | 1 03 Setup Guide Here’s how it works. You give commun ity strings to a Community Proper ty Group and the n appl y the Community Pr operty Group to an IPv4 range. For now, just add all your co mmunity strings to on e Property Group, the “glo bal” Community Property Group.
104 | Set up Network Discover y Network Discovery Activa te your pr oposed changes The Activate Changes page allows you to revi ew all the changes you have proposed for Netwo rk Discovery network configuration before actually making those change s take effect.
Check that it’s working | 105 Setup Guide Peregrine Systems recommends waitin g at least 48 ho urs while Network Discovery is first discovering your network. If you have concerns after th at, call customer support. Are de vices appearing on the Net w ork Map? Within the next few minutes, you can chec k that network discovery is occurri ng.
106 | Set up Network Discover y Network Discovery To check the Device Filters Report Click Status > Filtered devices To see a full list of po ssible filters, click Help > Classifications > Device Filters .
Refining Network Discovery | 107 CHAPTER 9 Refining Net w ork Disco v er y The procedures in this chapter are option al. You may wish to come back to this chapter after Network Discovery has been up and running for a while. Here you will learn how to take advantage of the precision Network Di scover y offers you for setting up Network Discovery.

A tree of IPv4 ra nges | 109 Setup Guide You will be creating a tree of ranges and the tree can be as complicated as necessary to have Network Discovery monitor your network the way you want. Note: A range can consist of one device. The start ing and ending IPv4 addresses are the same.
110 | Refini ng Network Discovery Network Discovery To merge IPv4 ranges 1 Administration > Network configu ration > Merge IPv4 ranges. Network Discovery displays all adjacent ranges sharing identical properties along with what the re sults of merge will be.
Network Pr operty Groups | 111 Setup Guide Administration > Network configuration > Network Pro perty Groups > List Network Pr operty Groups The list is a table with the names of the groups on the left and the names of the properties across the top.
112 | Refini ng Network Discovery Network Discovery The following properties are in every Network Property Group: Property Purpose Hardcoded Default Setting Allow devices Allow devices to be added Off.
How to use Network Property Groups | 113 Setup Guide How t o use Network Pr oper t y Gr oups Some of the propert y groups cause Network Discov ery to give you more da ta than others, but in doing so they also generate more traffic on th e network and cause more load on the device being moni tored.
114 | Refini ng Network Discovery Network Discovery Making changes to Netw ork Pr oper ty Groups You are unlikely to need to know how to create, modify, or delet e Network Property Groups. The default Network Pr operty Groups will almost cer tainly meet your needs, but if they do n’t, h ere are the instruction s.
Making changes t o Network Property Groups | 1 15 Setup Guide Crea te a Netw ork Propert y Gr oup Add a Network Property Gro up 1 Administration > Network configuration > Network Pro perty Groups > Add a Network Property Group. 2 Give your new Property Group a name.
116 | Refini ng Network Discovery Network Discovery Apply a Netw ork Proper ty Group to a range You might think of it as addi ng ranges that you want to subtract in some way from the preceding range. Each success ive range that you add takes all its properties from the range of which it is a subset—except the properties you specify for it.
Community Property Groups | 117 Setup Guide To create a Community Property Grou p 1 Administration > Network configuration > Community Property Group > Add a community property group. 2 Give a name to the Communit y Property Group. Use a name that is meaningful to you.
118 | Refini ng Network Discovery Network Discovery More on community strings If you do not add any commun ity strings, but keep “pub lic” (the default) in the list, Network Discovery will attempt to read the MIB of all devices in the defined IP range or set of rang es using only “public.
More on community s trings | 119 Setup Guide either disable all such traps o r use only a single correct community string for each device that issues a trap. Note: If another network managemen t system is used in the same network with Network Discovery, this other system may generate alarms due to these traps.
120 | Refini ng Network Discovery Network Discovery You have deleted a single community st ring from a Community Property Group in your proposed configuration, but your change will not take place until you activate changes.
Reviewing and activating your c onfiguration changes | 121 Setup Guide the strings you added. I t’s a shortcut to save you from entering IPv4 ranges more than once. You should always give your Property Sets meaningful names, for example “servers” or “routers” so you can apply it to specific portions of your network.
122 | Refini ng Network Discovery Network Discovery 2 If you wish to see details on the prop osed changes to the IPv4 ranges, you can click on the tree di agram to expand it. New ranges appear in green. Changes to existing ranges are in yellow. Removed ranges a re in grey.
Setting up Accounts | 123 CHAPTER 10 Set ti ng up A c c ou n ts Once you have set up th e Peregrin e appliance and configured Network Discovery, you will want to set up acco u nts. For each account, you can set the name, password, and other important information.
124 | Setting up Accounts Network Discovery How man y people c an use Netw ork Disco ver y a t once Network Discovery supports a maximum of 250 accounts. More than one account can be used at a time. Up to six accounts can view a Network Map simultaneously .
Creating accounts | 125 Setup Guide You should also modify the capab ilities of the account and the contact da ta for the person who owns the account. You can also modify the properties of the account , but this is optional ; the account owner can perfor m these actions on his or her own account.
