A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Network Node Manager i Software10.30

Overlapping Address Mapping Form

[This is the context-sensitive link for the Overlapping IP Address Mapping form]

If static Network Address Translation (NAT) is part of your network management domain, and the NNMi management server is outside of that static NAT domain, you can use Overlapping Address Mapping to configure NNMi for the following:

Populate the Mapped Address attribute of the IP Address form for the identified Tenant / NAT internal IP address. This Mapped Address attribute displays the corresponding NAT external IP address (public address).
Ensure that in the following special cases, Spiral Discovery successfully detects changes:
- The Communication Configuration you establish for a Node enables the Enable SNMP Address Rediscovery attribute (Configure communication protocol). This setting instructs NNMi to search for a new SNMP agent for the Node if the currently configured SNMP agent stops communicating for any reason (rather than waiting for the SNMP agent to come back online).
- The Monitoring Configuration you establish for a Node enables the Enable IP Address Fault Polling attribute (Monitor Network Health). This setting instructs NNMi to use ICMP. When using ICMP for this purpose, the Overlapping IP Address Mapping is required for each monitored internal address within the Static NAT.

Your network domains might use static NAT for duplicate addresses in enterprise local area networks (LANs), corporate offices, or residential networks. See Overlapping Addresses in NAT Environments for more information about possible network configurations.

Note If you are configuring NNMi for areas of your network management domain that use dynamic Network Address Translation (NAT) or dynamic Port Address Translation (PAT/NAPT), do not use this form. For more information: See Also

To configure NNMi to display static Network Address Translation (NAT) external IP address in the IP Address form, do the following:

Tip There is also a command line tool for this task nnmloadipmappings.ovpl.

Prerequisite: Configure each network management domain as a unique Tenant. See Configure tenants.
Navigate to the Overlapping Address Mapping view.
1. From the workspace navigation panel, select the Configuration workspace.
2. Select Discovery.
3. Select Overlapping Address Mapping.
Do one of the following:
- To create a new configuration, click the New icon.
- To edit an existing configuration, double-click the Overlapping IP Address Mapping definition you want to edit.
- To delete a configuration, select the Overlapping IP Address Mapping definition you want to delete and click the Delete icon.
Make your configuration choices, all three settings are required. (See the Overlapping IP Address Mapping Attributes table.)
Click Save and Close.

Note: If you reassign a Node from one Tenant to another Tenant, this setting does not automatically update.

Overlapping Address Mapping Attributes
Attribute	Description
Tenant	Designate which Tenant owns the Addresses you are mapping. See Configure tenants. Click the Lookup icon and do one of the following: To select an existing Tenant configuration, click the Quick Find icon To create a new configuration, click the New icon. Note This attribute value does not automatically update if the NNMi administrator reassigns the Node to another Tenant.
External Address	Provide the appropriate substitute address configured in static Network Address Translation (NAT) for the Internal Address (next value). The address you provide here shows up in the IP Address form's Mapped Address attribute if NNMi discovers the designated Tenant / Internal Address pair.
Internal Address	Provide the address that requires mapping. The External Address you map to this address appears in the IP Address form's Mapped Address attribute.
