The Device Viewer allows you to enter login credentials for a device in the network and test them. The device must already be recognized in NetMRI through discovery. Credentials can be specified for SNMP and for CLI.

To establish SNMP device credentials at the device level, perform the following:

  1. On the Network Explorer  page, do one of the following:
    • Click Inventory > Devices and then click a device IP.
    • Click Discovery and then click a device IP. The chosen device's Device Viewer appears.
  2. To open the page for creating SNMP login credentials, click Settings and Status > SNMP Credentials.
  3. Click the Edit button to enable changes to the current settings for device-specific SNMP information.
  4. Click Use SNMP v1/2c or Use SNMP v3. The options are mutually exclusive. For SNMP v1/2c, enter the community string for the device. For SNMP v3, enter the required authentication and privacy passwords and then choose their encryption protocols from the Auth. Protocol and Privacy Protocol drop-downs.
  5. Click Test to try out the new credential. You can also click Show Password to verify that you've entered the correct values. When you click Show Password, the table of credentials for the selected device displays a new Password column.
    For SNMP credentials, NetMRI tests against device-related OIDs such as sysUptime and sysDescr. The test is considered passed if these items are successfully polled. For SNMPv1/v2c tests, SNMP version 1 is used during the test.

    A test example is shown below:

    Test Starting

    +++ Checking SNMPv1/v2c [public] ................. Credential passed

    Discovered working credential for device after testing 1 credentials

    Test Completed

  6. Click Save. Saved credentials can be deleted by clicking the Delete icon in the table row.

The lower panel is a history that lists all credentials attempted during the last credential guessing attempt for the given device. This data resets each time credentials are guessed for a device. The table indicates the time of each guess and the result of that attempt. If a device is manually configured with a credential, NetMRI updates the history once it attempts to use that credential for data collection.
