In the Console, Configure Discovery Seeds

[This is the Context-Sensitive Help topic for the Discovery Config: Discovery Seeds form.]

Discovery seeds are sometimes optional and sometimes required. See Specify discovery seeds for details.

For the alternate method of configuring Discovery Seeds, see From the Command Line, Add Discovery Seeds and Add Multiple Seeds, Configure Discovery Seeds.

To add a discovery seed using the console:

  1. Complete all prerequisites. See Prerequisites for discovery, Concept Link IconSee Also.
  2. Do one of the following:

    • To add a discovery seed, click the  New icon.
    • To edit a discovery seed, double-click the row representing the discovery seed you want to edit.
    • To delete a discovery seed, select a row, and click the  Delete icon (see Delete Discovery Seeds and Delete Nodes for more information).
  3. Provide appropriate information (see table).

    NNMi uses information gathered from Routers to establish membership for Subnet connections. Make sure that important Routers in your network environment are SNMP enabled.

    NNMi uses either of the following criteria to identify a Router:

    • The Router responds to an SNMP query with appropriate values for sysServices (1.3.6.1.2.1.1.7) and ipForwarding (1.3.6.1.2.1.4.1). See RFC 1213, MIB-II for details.
    • The Router responds to an SNMP query with an appropriate MIB-II sysObjectID value according to the current settings in NNMi's Device Profile configuration.

    You must provide the appropriate SNMP Community Strings to NNMi.

  4. Click  Save and Close to return to the Discovery Configuration form.

    Tip Click the  Save and New icon to continue to adding discovery seeds.

  5. Click  Save and Close. As soon as you enter one or more discovery seeds, discovery begins.

Discovery Seed Definition
Attribute Definition
Hostname / IP

To identify the node, enter one of the following:

  • Fully-qualified hostname of the discovery seed (not case-sensitive)
  • IP address of the discovery seed

    If you specify an IP address, NNMi uses that IP address only during initial discovery of the Seed. NNMi then requests the current Management Address (the address from which the node's SNMP Agent responds) and uses that IP address for all communication after initial discovery.

Caution For nodes with addresses provided by Network Address Translation (NAT) protocols, use the appropriate address:

  • Static Network Address Translation (NAT):

    • If the NNMi management server is outside the NAT domain - use the node's external IP address
    • If the NNMi management server is inside the NAT domain - use the node's internal IP address
  • Dynamic Network Address Translation (NAT) - use the node's internal IP address.
  • Dynamic Port Address Translation (PAT/NAPT) - use the node's internal IP address.

The IP addresses in the following table cannot be used as Discovery Seeds or Auto-Discovery Hints. NNMi still Discovers and Monitors these addresses within the context of a Node, but NNMi does not gather information about neighbors from these addresses.

Invalid IP Addresses for Discovery Seeds or Auto-Discovery Hints
IPv4 Address Range IPv6 Address Range Explanation
0.*.*.* not applicable Reserved IP addresses
0.0.0.0 ::0 Any Local (listen) address
127.*.*.* ::1 Loopback addresses
not applicable fe80::*:*:*:* IPv6 link-local addressA non-routable IPv6 unicast address only used for communication with other nodes on the same link (LAN or VLAN). Link local addresses cannot be used for communication that must be forwarded through a router. IPv6 auto-configuration automatically assigns a unique link local address in the fe80::/10 address space to each IPv6-enabled interface on a system.
224-239.*.*.*

not allowed (ff00:: to ffff:ffff:ffff:ffff:ffff:ffff:ffff)

multicast addressUsed to identify a group of hosts joined into a group. IPv4 multicast addresses are in the range 224.0.0.0 to 239.255.255.255 and IPv6 multicast addresses have the prefix ff00::/8.
255.255.255.255 not applicable Broadcast address
Initial Discovery Tenant

For the Initial Discovery Tenant setting, do one of the following:

  • Leave this attribute empty (blank). NNMi assigns each Node to the Default Tenant (and whichever Initial Discovery Security Group attribute value is currently assigned to the Default Tenant).
  • Optional. Assign a Tenant to a particular seed before discovery. See Configure tenants and About Security Groups for more information.

    • Click the drop-down icon to see the list of previously configured Tenant names or Tenant UUIDUniversally Unique Object Identifier, which is unique across all databases.s. Use the auto-complete feature to quickly specify which tenant.

      Tip You can also click the  Lookup icon and select  Quick Find for the list of previously defined tenants.

    • To define a new Tenant, click the  Lookup icon and select  New.
Discovery Seed Results An automatically generated value. The most recent discovery status for this discovery seed. See Discovery Seed Results for details. 
Last Modified The date and time of the last change in Discovery Seed Results.
