Testing SNMP and CLI Credentials

After configuring SNMP and CLI credentials, you can click Test Credentials in the SNMP Credentials or CLI Credentials panel to test the credentials. Credential testing ensures that the configured credentials work for as many devices and networks as possible. The procedure in this section applies to both the Grid and the member levels. You can override the Grid settings at the member level.

For CLI credentials, you can test an admin login name and password tuple as well as a following enable credential, if necessary. You can also override CLI credentials and enable credentials for IPAM objects such as fixed addresses, IP reservations, and host objects. You can test any credential set, an enable credential, or both in combination against any device within any network view. Network Insight sets the login sequence to match the command-line standards for the selected device.

To test SNMP credentials or CLI credentials, complete the following:

1. From the Grid tab, select the Grid Manager tab, and then click Discovery.

2. For the Grid: Click Edit > Grid Discovery Properties in the Toolbar.
   For a Probe member: Select a member checkbox, and then click Edit > Member Discovery Properties in the Toolbar.

3. In the Grid Discovery Properties or Member Discovery Properties Editor, click the Credentials tab > SNMPv1/v2 tab, SNMPv3 tab, or CLI tab.

4. Select the checkbox or checkboxes for the Login credentials and/or Enable credentials (if applicable) you want to test.
   For a Probe member, click Override, and then select the credential checkboxes.

5. Click Test Credentials.

6. In the Test SNMP Credentials or Test CLI Credentials dialog box, complete the following:

   • IP Address: Select this to test the credential against an IP address of a reachable device in a network (even if it has not been discovered or managed through NIOS) within a specified network view. Enter the IP address in the field. Ensure that you select the respective network view in which this IP address resides.

   • Network View: If you have multiple network views, select the network view in which the IP address resides from the drop-down list. If you have only one network view, which is the default view, the Network View drop-down list is hidden by default. NIOS conducts credential testing for the IP address in the selected network view.

   • Device: Select this to test against a selected device. Click Select Device and the Device Selector appears. If you have multiple network views, you must first select the network view in which the device resides from the Network View drop-down list, located at the upper left-hand corner of the selector. If you have only one network view, which is the default view, the Network View drop-down list is hidden by default. You can check the device categories under All Devices to locate discovered switches and routers or any unmanaged devices previously detected by discovery under NIOS. You can explore categories including Discovered Switches/Routers, Microsoft Windows Devices (this can include items such as Windows Servers of various types), Router and Wireless Access Point Devices, Unmanaged, and others. By default, all devices previously discovered appear in this selector. If you have a long list of devices, you can enter a device name search value or a search expression in the Find field and click Go. You can also click Show Filter to narrow down your selection by selecting available filters. Click OK after you have selected a device and its corresponding network view.

7. Click Start to begin testing the credential against the IP address or selected device. The communication and testing processes appear in the lower panel of the editor.
