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||
- Configure Trap Forwarding
Configure NNMi SNMPv3 Security Settings for Trap Forwarding and Inform-Requests
Note If your network environment uses SNMPv2c or SNMPv1 and does not use SNMPv3, skip this task.
If your network environment uses SNMPv3, specify which user-based security model (USM) settings the NNMi management server uses when NNMi acts as an authoritative entity in the following situations:
- Forwarding SNMPv3 traps to other devices in your network environment
- Sending responses to SNMPv3 Inform-Requests
The settings in this form grant permission for NNMi to communicate with the SNMPv3 agent. The SNMPv3 engine identifier and the user-based security settings are required for successful authentication in SNMPv3 protocol. Devices that are sending SNMPv3 informs to NNMi must use these settings.
To configure the NNMi management server as an authoritative entity for SNMPv3:
Navigate to the Trap Forwarding Configuration form.
- From the workspace navigation panel, select the Configuration workspace.
- Expand the Incidents folder.
- Expand the Trap Server folder.
- Select Trap Forwarding Configuration.
- Navigate to the NNMi SNMPv3 Trap Forwarding Security Settings group.
NNMi displays the ID of the engine assigned to the SNMPv3 agent that NNMi uses when forwarding or sending data to other SNMPv3 agents. See the attribute value for Engine Id.
Caution Devices that are sending SNMPv3 informs to NNMi must use these settings.
- Provide the USM information that NNMi uses for authentication and privacy when using SNMPv3 protocol for forwarding traps or receiving Inform-Requests from other devices in your network environment (see table).
- Click Save and Close to save your changes.
|User Name||The SNMPv3 User Name is the text string used for SNMPv3 requests in your network environment.|
The SNMPv3 authentication protocol. Determines whether authentication is required and indicates the type of authentication protocol used. NNMi supports the following protocols:
The SNMPv3 USMUser-based Security Model authentication passphrase used by the NNMi management server. If required for authentication, provide the appropriate authentication passphrase for the authentication protocol.
The length limitations of the authentication passphrase depend on the authentication protocol.
Specify the SNMPv3 USMUser-based Security Model privacy protocol used by the NNMi management server.
The SNMPv3 USM privacy protocol determines whether encryption is required and indicates the type of privacy protocol used. NNMi supports the following privacy protocols:
Note Leaving this attribute empty means SNMP Minimum Security Level = No Privacy for this SNMPv3 configuration.
Specify the SNMPv3 USMUser-based Security Model privacy passphrase used by the NNMi management server.
If required for privacy, provide the appropriate encryption passphrase for use with the privacy protocol.
The length limitations of the privacy passphrase depend on the privacy protocol.
