Add Multiple Seeds, Configure Discovery Seeds

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

For the alternate method of configuring Discovery Seeds, see In the Console, Configure Discovery Seedsor From the Command Line, Add Discovery Seeds.

To add multiple discovery seeds using a seed file:

1. Complete all prerequisites. See Prerequisites for discovery, See Also.

2. Using a text editor, create a list of seeds, one per line, using the following syntax (see table below for more details):

   <IP Address or HostName>, "<optional Tenant Name or UUID>" # <optional Notes text>

   Note The directory and filename of the seed file must be accessible for non-root users.

3. Navigate to the Seeds view.

   1. From the workspace navigation panel, select the  Configuration workspace.
   2. Expand Discovery.
   3. Select Seeds.

4. Select any row and do one of the following:

   • Click Actions → Add Multiple Seeds.
   • Right-click any row and select Add Multiple Seeds.

5. Follow the instructions in the Add Multiple Seeds dialog.

Discovery Seed Definition

Attribute	Definition
Hostname / IP Address	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. (NNMi Advanced) When providing IPv6 addresses as discovery seeds, use IPv6 notation as defined in RFC 2373. Click here for more information. 16-byte (128-bit) address, composed of eight groups of 2-byte (16-bit) hex values separated by colons (XXXX:XXXX: XXXX:XXXX: XXXX:XXXX: XXXX:XXXX) Uppercase and lowercase (A-F/a-f) permitted for the hex digits. Note NNMi displays IPv6 addresses as all lowercase. Optional. Omit leading zeros in each 2-byte hex value. :: means a single contiguous sequence of all zero 2-byte hex values. However, :: is permitted only one time per address. For example, the following three IPv6 address notations are equivalent: 2001:0D88:0000:0000:0008:0800:200C:417A 2001:d88:0:0:8:800:200c:417a 2001:d88::8:800:200C:417a For the right-most 32-bits, IPv4 dotted-decimal notation can replace the pair of 2-byte hex values. For example, the following two IPv6 address notations are equivalent: 2001:D88::5efe:10.7.150.201 2001:D88::5efe:a07:96c9 Types of IPv6 Addresses IPv6 Address Range Explanation 0::to 1fff:ffff:ffff:ffff:ffff:ffff:ffff unassigned or reserved 2000:: to 3fff:ffff:ffff:ffff:ffff:ffff:ffff global unicast address(2000:: to 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff) A publically routable IPv6 unicast address, used for communication between nodes anywhere on the internet. The first part of the address is a global routing prefix in the 2000::/3 address space for your organization (assigned by the Internet Service Providers). The complete host address can either be manually configured or automatically assigned using IPv6 auto-configuration and neighbor discovery. fd00:: to fdff:ffff:ffff:ffff:ffff:ffff:ffff unique local address(fd00:: to fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff) A privately routable IPv6 unicast address used only for communication between nodes within your organization. The unique local addresses cannot be routed to the public internet. The address consists of a routing prefix in the fd00:/8 address spaces, assigned locally by your organization. And the full host address might be manually configured or automatically assigned using IPv6 auto-configuration and neighbor discovery. 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.
Notes	Provide any additional information about this discovery seed that would be useful to you or your team. Type a maximum of 1024 characters. [Notes & Description]Use any combination of alpha-numeric characters, multibyte characters (such as Japanese), spaces, punctuation, and special characters (~ ! @ # $ % ^ & * ( ) _+ -).
