Device entries created in Device Manager
The following table lists the fields populated in a device entry by device discovery. For more information about the Device Manager, see
Controlling Direct Collection.
When NetIM successfully connects to a device using SNMP during the discovery phase, the corresponding device entry contains enough information for SNMP collection. Additional fields are required to successfully connect to a device using command-line interface (CLI). This additional information is filled in the device entry during the autoconfiguration phase of device discovery.

1 The access address may be outside of the discovery range if the device has at least one interface with an IP address in the discovery range.
2 Determined by Device Discovery during the access configuration phase, if successful CLI credentials are supplied.
3 These CLI credentials are set in the device entry only if the user-supplied credentials lead to successful CLI login to the device.
Device discovery may find a device through more than one IP address; however it will only create one entry in the Device Manager. When determining which of the IP addresses to use as the Access Address for the device entry, it attempts to identify a loopback address in the domain defined by the Include Addresses List through which the device is both SNMP and CLI accessible. If it cannot identify such an address, it chooses the best IP address in the Include list range. If no Include list was provided, the discovery engine chooses the best address available. It is possible that the chosen address will be outside of the domain defined by the Include Addresses List and/or a non-loopback address.
