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 the default device credentials

[This is the Context-Sensitive Help topic for the Default Device Credentials tab on the Communication Configuration form and the Default Device Credentials form.]

NNMi uses the Device Credentials settings for the following:

Device discovery of some vendor-specific devices that require non-SNMP communication, such as Netconf over SSH. For a list of the these devices see the NNMi Device Support Matrix.
Device Diagnostics
Requires Network Node Manager iSPI Network Engineering Toolset Software (NNM iSPI NET) and requires installation of a Diagnostic Server.
(NNMi Advanced) Last resort discovery for hypervisor discovery when neither of the following are available:
- Region configurations for each area authorized by a CA certificate (one per organization, used to validate all hypervisors within the organization).
- Specific node configurations for each hypervisor authorized by a Self-Signed Certificate.

NNMi uses the following sequence to determine Device Credentials:

Use the Specific Node Device Credentials. If none match, continue.
Use the Region Device Credentials. If none match, continue.
Use the Default Credential settings (provided here).

To provide the default credentials setting:

Navigate to the Default Device Credentials tab.
1. From the workspace navigation panel, select the Configuration workspace.
2. Select Communication Configuration.
3. Navigate to the Default Device Credentials tab.
Click New. The Default Device Credentials form opens.
Provide the default attribute values.
Click Save and Close to return to the Communication Configuration form.
Click Save and Close to apply your changes.

NNM iSPI NET uses the Default Credentials setting to access devices when running Diagnostics either automatically or when the Actions > Run Diagnostics option is used.

You can also right-click any object in a table or map view to access the items available within the Actions menu.

At each level in the sequence to determine the Device Credentials (see bullet list above), NNMi first uses Secure Shell (SSH) to establish a secure connection, and if the SSH attempt fails, NNMi tries Telnet protocol as the communication method.

Caution By default, neither Microsoft Internet Explorer nor Mozilla Firefox defines the telnet command nor the SSH command, so using either of these menu items produces an error message.

Default Device Credential Attributes
Attribute	Description
Type	Select one of the following: Shell Use this setting to provide credentials for NNMi to use when communicating with devices using Secure Shell (SSH) or Telnet protocol. VMware Use this setting to provide credentials for NNMi to use when communicating with VMware ESXi servers using VMware VSphere® WebService.
User Name	Type the user name that you want NNMi to use for logging into devices by default (when no Region or Specific Node settings work).
Password	Type the password that you want NNMi to use for logging into devices by default (when no Region or Specific Node settings work). NNMi encrypts the password and displays asterisks for this attribute. If you want to change the password, first clear the asterisks displayed in the Password attribute and enter the new Password value.
