    Network Discovery Note: Network Discovery defines a node as any network device with at least one MAC address. A managed device is a network device that has an SNMP agent and MIB so it can respond to SNMP requests. How many nodes do you believe are active on your network? Are there any remote sites to be managed? If yes, approximately how many managed nodes are at remote sites? Is your network divided into subnets?

  • Page 24: Turn On Snmp Management In All Routers And Core Switches

    Network Discovery Turn on SNMP management in all routers and core switches Depending on the device, this may be a case of enabling an existing SNMP agent or setting up an SNMP agent. You may also turn on SNMP management in other devices. The more managed devices in your network, the better.

  • Page 25: Set Dhcp Lease Time

    Set DHCP lease time If you use DHCP (Dynamic Host Configuration Protocol) in your network, set the IP address lease time to at least 7 days and turn on SNMP management on the DHCP servers. About community strings A community string is like a password. A device uses a community string to protect its SNMP MIB—and it’s the data from the SNMP MIB that Network Discovery relies on.

  • Page 26: (Optional) Adjust Bridge Aging

    Network Discovery What happens if a device with directed community strings is not configured with the IP address of the Peregrine appliance? Network Discovery will behave as though the device does not have SNMP management turned on. Network Discovery will appear to work, but you’ll eventually notice that it is working poorly.

Run Router Discovery Set up IPv4 Ranges to Discover Set up IPv4 Ranges to Avoid Set up Specialty IPv4 Ranges (DHCP and unmanaged routers)

  • Page 96: How It Works

    Network Discovery Important: If you are using Network Discovery with Desktop Inventory, you must follow the steps outlined in Using Network Discovery with Desktop Inventory and Desktop Administration. How it works Essentially, network configuration works as follows. You add IPv4 ranges that you want Network Discovery to monitor.

  • Page 97: Set Up The Ipv4 Range(S) To Discover

    Note: The list of community strings must be separated by commas (for example, “public,private,string1,string2”). Click Change. Note: Hop 0 (zero) is always the Peregrine appliance itself, and hop 1 is always the default gateway. Run Router Discovery Click Administration > Router discovery > Run router discovery. Click Confirm.

  • Page 98: Import Your Ipv4 Ranges From A Csv File

    Network Discovery Import your IPv4 ranges from a CSV file Instead of entering all your IP ranges manually, you can import them from a CSV file. The file must be set up properly, as in the example below. State whether this Starting IP is a range or a address...

  • Page 99: View An Ipv4 Range

    Groups/Sets in the CSV file, and you do not select a default, the IP range will not be imported. Click Import. Once you import the CSV file, you will see a report explaining whether or not the import was successful. Read the report carefully to ensure that all your IPv4 ranges have been imported properly.

  • Page 100: Add An Ipv4 Range

    Network Discovery To delete an IPv4 range From Administration > Network configuration > List IPv4 ranges. Select the IPv4 range. If the range has subranges, Network Discovery gives you a choice of deleting only the range or of deleting the range plus all of its subranges. Click Delete this IPv4 range.

  • Page 101: Set Up The Ipv4 Range(S) To Avoid

    For Property Set/Group, select Network: Active Discovery. Network Discovery will perform network discovery (ping, poll, and table read) on the range you have entered. Click Submit. Repeat step 1 to step 4, if necessary, for all your subnets. You have added the range(s) to discover to your proposed new configuration, but your changes will not take effect until after you have reviewed and activated your changes.

  • Page 102: Add Ranges For Dhcp Servers And Unmanaged Routers

    Network Discovery Add ranges for DHCP servers 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 the ranges differently. To add IPv4 addresses to be treated as DHCP servers or unmanaged routers Click Administration >...
  • Page 103 Here’s how it works. You give community strings to a Community Property Group and then apply the Community Property Group to an IPv4 range. For now, just add all your community strings to one Property Group, the “global” Community Property Group. Note: Community strings are case-sensitive.

  • Page 104: Activate Your Proposed Changes

    Network Discovery Activate your proposed changes The Activate Changes page allows you to review all the changes you have proposed for Network Discovery network configuration before actually making those changes take effect. Note: Changes to network configuration do not take effect if you do not activate them.

  • Page 105: Are Devices Appearing On The Network Map

    Peregrine Systems recommends waiting at least 48 hours while Network Discovery is first discovering your network. If you have concerns after that, call customer support. Are devices appearing on the Network Map? Within the next few minutes, you can check that network discovery is occurring. To check that network discovery is occurring Click Status >...

    Network Discovery To check the Device Filters Report Click Status > Filtered devices To see a full list of possible filters, click Help > Classifications > Device Filters. Check the Device Modeling Queue During the initial discovery of your network, the modeling queue may show devices, depending on the size of your network and how quickly Network Discovery is discovering and modelling devices.

  • Page 107: Refining Network Discovery

    Refining Network Discovery CHAPTER The procedures in this chapter are optional. 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 Discovery offers you for setting up Network Discovery.

  • Page 108: A Tree Of Ipv4 Ranges

    Network Discovery You can leave discovery set up that way, if it is satisfactory to you. In fact, if there is a lot of change in your network, leaving it alone may be the best thing to do. However, you can set discovery up more precisely. For instance, you may want to reduce overhead on the network, or you may have a lot of community strings for security reasons and want to set up separate ranges for them.
  • Page 109 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 starting and ending IPv4 addresses are the same.

  • Page 110: Property Groups

    Network Discovery To merge IPv4 ranges Administration > Network configuration > Merge IPv4 ranges. Network Discovery displays all adjacent ranges sharing identical properties along with what the results of merge will be. Click Merge. You have merged any adjacent identical IPv4 ranges in your proposed new configuration.

  • Page 113: How To Use Network Property Groups

    How to use Network Property Groups Some of the property groups cause Network Discovery to give you more data than others, but in doing so they also generate more traffic on the network and cause more load on the device being monitored. It can be a trade-off, a balance between efficiency and performance.

  • Page 114: Making Changes To Network Property Groups

    Network Discovery Property Group Passive Discovery Restrict to scanned-only Remove Address All off Making changes to Network Property Groups You are unlikely to need to know how to create, modify, or delete Network Property Groups. The default Network Property Groups will almost certainly meet your needs, but if they don’t, here are the instructions.

  • Page 115: Create A Network Property Group

    Create a Network Property Group Add a Network Property Group Administration > Network configuration > Network Property Groups > Add a Network Property Group. Give your new Property Group a name. Give your new Property Group a description. For each parameter, click On or Off or leave it at the default value, Inherit. Click Submit.

  • Page 116: Apply A Network Property Group To A Range

    Network Discovery Apply a Network Property Group to a range You might think of it as adding ranges that you want to subtract in some way from the preceding range. Each successive range that you add takes all its properties from the range of which it is a subset—except the properties you specify for it.
  • Page 117 To create a Community Property Group Administration > Network configuration > Community Property Group > Add a community property group. Give a name to the Community Property Group. Use a name that is meaningful to you. Add a description. Under the heading Add a Community String enter a string name, and select the appropriate Type (read or write, or both).

  • Page 118: More On Community Strings

    Network Discovery More on community strings If you do not add any community strings, but keep “public” (the default) in the list, Network Discovery will attempt to read the MIB of all devices in the defined IP range or set of ranges using only “public.” Note: If you do not add any community strings and delete “public”...

  • Page 119: Directed Community Strings

    either disable all such traps or use only a single correct community string for each device that issues a trap. Note: If another network management system is used in the same network with Network Discovery, this other system may generate alarms due to these traps.

    the strings you added. It’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. You can list, add, modify and delete Property Sets, the same way you do with Property Groups.
