Configuring Device Credentials

Credentials apply to devices at the following levels:

• The Grid: Settings apply across the Grid and all Probe appliances licensed for Discovery.

• Discovery Probe appliances: You can use inherited Grid settings or override them.

• Individual devices: You can use inherited Grid or Probe settings or override them with device-specific settings.

You can configure the following types of device polling credentials:

• SNMPv1/v2 Credentials

• SNMPv3 Credentials

• CLI Credentials

Once configured, you can test the credentials.

For more information on configuring device credentials, see the following sections:

• Configuring SNMPv1/v2 Credentials

• Configuring SNMPv3 Credentials

• Configuring CLI Credentials

• Defining CLI Credentials for Objects

• Testing SNMP and CLI Credentials

If any SNMP or CLI credentials become obsolete, you can reset them for all affected devices at once. After that, Network Insight re-guesses the credentials for each device. This does not apply to CLI credentials manually set for specific devices. For more information, see the reset snmp and reset cli Administrative Shell commands.

You can assign a credential to a credential group that is specific to a particular device group. For more information about credential groups, see Configuring Credential Groups below.
