Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
|A single word||
||Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".|
You can specify that the search results contain a specific phrase.
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.
Two or more words in the same topic
|Either word in a topic||
|Topics that do not contain a specific word or phrase||
|Topics that contain one string and do not contain another||
|A combination of search types||

Managing Overlapping IP Addresses in NAT Environments
NNMi helps you manage areas of your network that include Network Address Translation (NAT) domain implementations (potentially causing duplicate IP addresses, and requiring NNMi configuration for handling the NAT internal/external IP address pairs). NNMi administrators identify each NAT domain by creating a Tenant definition. NNMi identifies each Node by using a Tenant / IP address pair. Addresses are not considered duplicates unless they are duplicated within one Tenant’s group of Nodes.
Note Duplicate IP addresses outside of the context of NAT domain integrations: If your network includes firewall or load-balancer devices that have duplicate IP addresses / MAC addresses (such as virtual instances hosted on a physical device). The NNMi administrator populates a configuration file with the sysObjectId values of the firewall and load-balancer. Then, NNMi successfully acknowledges each instance of a Node object having those sysObjectId values (rather than merging all as if they were the same Node object).
