- From the Data Management tab, select the IPAM tab. The IPAM Home page appears.
- Expand the Toolbar and click Discovery Status.
The same Discovery Status button can be found under Data Management –> Devices.
The Discovery Status table lists detailed information about network devices and end hosts discovered through all methods, including SNMP, ICMP ping sweeps and other processes.- IP Address: the IPv4 or IPv6 address of the discovered device. You can filter the table by this value.
- Name: The name of the discovered device as reported through SNMP. You can filter the table by this value.
- Type: The discovered device type. Examples include Router, NIOS, Switch-Router, Firewall, Load Balancer, and numerous others.
- Overall Status: Indicates the overall success or failure of the discovery task on the device. Hover the mouse over the device to see more detailed information about the discovery status, including the timestamp of the last discovery event, confirmation of detection ("Device Exists"), and the means of detection, which are usually methods such as SNMP, reading the ARP table or location through a Seed router. You can filter the table by this value.
- Reached Status: Indicates the reachability of the discovered device. Typically, devices are reported Passed for Reached Status if they are reachable through SNMP, a path trace through ICMP, or UDP-based path tracing for an IPv6 address.
You may see a Reached Status of Passed and still receive an Overall Status of Failed. This often occurs because either the CLI credentials or SNMP credentials provided for discovering the device do not work, or another problem occurs in some part of the discovery process. - SNMP Collection Enabled: Indicates whether the managed device allows SNMP as a management protocol. This value shows Yes or No. You do not see any SNMP collection status updates if this value shows No.
- SNMP Credential Status: Indicates whether the correct SNMP credential is used by discovery. Usually shows simple Passed or Failed status. Passing the mouse over the Failed status reading for this column shows the location in the SNMP data collection where information gathering failed. The typical message for a failure of this type typically shows Failure to Authenticate, which simply means that the correct SNMP credentials have not been provided for either SNMPv1, SNMPv2c or SNMPv3 as required and defined for the device's discovery configuration.
If SNMP Credential Status shows Failed, you do not see a value under SNMP Collection Status, because that is dependent on successful credential authentication. Should you succeed in SNMP Credential Authentication for a device, this value shows Passed. - SNMP Collection Status: Indicates whether managed device information has been successfully collected from the device. If the current device shows an SNMP Credential Status of Failed, this field remains blank. Should you succeed in SNMP Credential Authentication, SNMP Collection Status may or may not show a Passed outcome. If the final outcome is successful, passing the mouse over the table value shows the SNMP data set that was successfully collected from the device. When theSNMP Collection Status is set to Passed, it indicates that the credentials provided in Member Discovery Properties for discovering the device are correct and discovery has completed successfully on the device. For more information, see Defining the Discovery Member Type.
- CLI Credential Status: Reports the basic success state of CLI credential usage for device discovery. When you see a Failed status in this column, hover the mouse over the table value. Details related to failed CLI credentials normally relate to "Failed to Authenticate" events. (For more information, see the following subsection Analyzing Discovery Status.) If you define device discovery requirements to use both SNMP and CLI, and you receive complete SNMP discovery information but fail to authenticate for CLI, the Overall Status for the device remains as Failed.
- CLI Collection Enabled: indicates the CLI collection configuration state for the discovered or managed device. Possible values are Yes (CLI collection is enabled) or No (CLI collection is disabled for the device).
- Fingerprint Status: Shows the status of discovery of the device's OS through fingerprinting.
- Last Update: Timestamp showing the conclusion of the last data update for the current device.
- First Seen: Timestamp showing the initial discovery event.
- Last Seen: The date and time when the device was last successfully polled by discovery.
- Last Action: The last action performed by discovery upon the device after the discovery took place. Hover the mouse over this field to obtain details.
Visible columns can be changed in the Discovery Status window. At the top of any column header, click the down arrow tool, and choose Columns – > Edit Columns.
