5.3.1.3 Credential Discovery and MIB II information
Automatic discovery uses the list of credentials configured on the Default Credentials
page (Devices > Device Management > Discovery Credentials) to determine the correct
SNMP v2/v3 credentials and/or HTTP (or HTTPS) credentials for the device. Once the
correct credentials are determined, automatic discovery retrieves MIB II information
from the device and populates this information in the DCR.
page (Devices > Device Management > Discovery Credentials) to determine the correct

correct credentials are determined, automatic discovery retrieves MIB II information
from the device and populates this information in the DCR.
5.3.1.3.1 Auto-Discovery IP Address Filters
Both the include and exclude filters can be applied for the automatic discovery process.
The exclude filter is applied first, before the include filter. You provide the order of the
filters in the include and exclude filter lists, and the filters are applied strictly in this
order. Once a device IP address satisfies a filter, other filters will not be applied to the
device.
For example, if you configure the filters as follows:
Exclude Filter
12.*.*.*, 12.12.*.*
Include Filter
*.*.*.*, 14.*.*.*
In the above case, the filter 12.*.*.* overrides 12.12.*.* and so 12.12.*.* will never be
applied and is not required. Similarly *.*.*.* overrides 14.*.*.*.
The effect of these two filter lists operating in conjunction is that all device IP addresses
except those in the range 12.[0-255].[0-255].[0-255] will be discovered and populated in
the DCR.
Remember that the exclude filter is applied before the include filter.
Consider three devices with the IP addresses 12.12.12.12 ,14.14.14.14, and 20.20.20.20.
We show a few examples of filter settings that determine which of these devices are
discovered and populated in the DCR, and which are excluded.
The following cases provide examples of possible device discovery filtering scenarios:

The following cases provide examples of possible device discovery filtering scenarios:
Case 1: Configuring using the include and exclude filters.
Device
― 14.14.14.14
20.20.20.20
12.12.12.12
Exclude Filter
12.*.*.*
Out of range
Out of range
Within range
Include Filter
14.*.*.*
Within range
Out of range
Not applied
Result
― Included Excluded

Case 2: Include filter not specified, so the default (. *.*.*.*) is used.
Device
― 14.14.14.14
20.20.20.20
12.12.12.12
Exclude Filter
12.*.*.* - 13.*.*.*
