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.

Configure default SNMPv3 settings

Use the Default SNMPv3 Settings tab to provide default SNMPv3 user-based security model (USM) settings. For each address, NNMi checks the communication configuration settings in this order: communication protocols for specific nodes, communication protocols for network regions, and if no match is found, NNMi tries these default user-based security model (USM) settings. If NNMi discovers a device for which no SNMP settings are provided, that device is treated as a Non-SNMP device.

During initial discovery, NNMi tries many SNMP configuration settings until a match is found. After a match is identified for a Node, the information is recorded to prevent future authentication errors.

If you provide SNMPv3 user-based security model (USM) settings for a specific device, NNMi honors your choice and does not try any Region or Default settings for that device.

NNMi uses SNMP queries for ongoing discovery and monitoring of your network environment. SNMPv3 user-based security model (USM) settings are used to authenticate messages sent from NNMi to an SNMP agent. NNMi uses SNMP to gather useful information about the devices in your network environment. After receiving an SNMP request, an SNMP agent compares the SNMPv3 user-based security model (USM) settings in the request to the SNMPv3 user-based security model (USM) settings that are configured for that SNMP agent. The SNMP agent responds to the request only when the request is accompanied by valid SNMPv3 user-based security model (USM) settings.

During NNMi installation, any SNMPv3 user-based security model (USM) settings that were provided are automatically stored in the table on the Default SNMPv3 Settings tab.

Provide any number of additional SNMPv3 user-based security model (USM) settings that are used broadly in your environment (for example, by default). The order in which your SNMPv3 user-based security model (USM) settings appear in this table does not matter. NNMi checks all Default SNMPv3 Settings at a particular security level in parallel.

NNMi uses Default SNMPv3 user-based security model (USM) settings to access devices.

To view the current list of default SNMPv3 USM settings:

Navigate to the Default SNMPv3 Settings tab.
1. From the workspace navigation panel, select the Configuration workspace.
2. Select Communication Configuration.
3. Navigate to the Default SNMPv3 Settings tab.
The displayed table lists the Unique Name of each default SNMPv3 USM setting.

NNMi tries to use the Specific Node SNMPv3 Settings. If none match, NNMi tries the Region SNMPv3 Settings. If none match, NNMi tries the default SMNPv3 settings provided here.
You can do the following:
- To establish a new setting, click the New icon.
  
  Click Save and Close to return to the Default SNMPv3 Settings form.
- To edit an existing setting, select a row, click the Open icon.
  
  Click Save and Close to return to the Default SNMPv3 Settings form.
- To delete an existing setting from the Default list, select a row and click the Delete icon.
  
  The record remains in the database for possible use elsewhere and is simply removed from the Default list.

Default SNMPv3 Settings form

NNMi can use SNMPv3 user-based security model (USM) settings to access devices.

NNMi tries to use the current SNMPv3 Settings attribute value from Specific Node Settings. If none match, NNMi tries the Region SNMPv3 Settings. If none match, NNMi tries the default SMNPv3 settings provided here.

To configure a Default SNMPv3 Setting:

Navigate to the Default SNMPv3 Settings form.
1. From the workspace navigation panel, select the Configuration workspace.
2. Select the Communication Configuration.
3. Navigate to the Default SNMPv3 Settings tab.
4. Do one of the following:
  - To create default SNMPv3 Setting definition, click the New icon.
  - To edit a default SNMPv3 Setting, select a row, click the Open icon.
Click the SNMPv3 Settings Lookup icon and select one of the options from the drop-down menu:
- Show Analysis to display Analysis Pane information for the currently configured (selected) SNMPv3 Setting name.
- Quick Find to view and select from the list of all existing SNMPv3 Settings.
- Open to display the details of the currently configured (selected) SNMPv3 Setting.
- New to create a new SNMPv3 Setting.
Click Save and Close to return to the Default SNMPv3 Settings form.
