- Include non-network devices: Enables collecting end-host network segments into a basic device group to avoid expanding system processing cycles on network devices that do not require them.
- Rank: For more information, see Ranking Device Groups.
- Polling Frequency: Allows you to modify the default polling frequency for all devices or for specific device groups. For more information, see Creating Extended Device Groups.
- Switch Port data collection: Enable this only for device groups with L2/L3 Ethernet switching devices as members. This allows you to enforce custom periodic or scheduled polling settings for specific groups. For more information, see Device Groups and Switch Port Management.
- Collect performance and environmental data: Enable or disable device performance and environmental information. For more information, see Changing Performance Data Collection Settings.
- Probe for open ports: Allows NetMRI to probe for open TCP/UDP ports on member devices.
- Identify device using fingerprinting: For more information, see Defining Group Data Collection Settings.
- Probe for NetBIOS name: For more information, see Defining Group Data Collection Settings.
- Analyze for Issues: For more information, see Evaluating Issues in NetMRI and Viewing Device Issues, Configurations, and Changes.
- Test for default credentials: Allows NetMRI to test all devices in the group for the presence of vendor default SNMP credentials, which are a potential element for security breaches, but are also used for assistance in collecting device configurations. Credential default testing is also a compliance measure.
- Collect config files: For more information, see beginning with Configuration Management.
- Regard configurations as 'Locked': Disallows editing of any collection configuration files for members of the device group.
- Allow script execution: Allows the execution of Perl and CCS scripts on group member devices.
- Enable Discovery Blackout: Define time periods when NetMRI will not communicate with devices or networks for discovery.
- Enable Change Blackout: Define blackouts for CLI interaction, scheduled or run-now job executions, Telnet/SSH proxy, and port control UI features for all devices in the group. For more information, see Defining Blackout Periods.

- Click the Settings icon > Setup > Collection and Groups > Groups.
- Click Add to create a top-level, sibling, or child extended group.
- In the Parent ID field, NetMRI automatically sets the ID of the parent group. It is "0" for a top-level or sibling group.
- Enter a Name for the group. The group name is shown in all group-related displays and reports, so the group name should be meaningful without being too long.
Define a Membership Criteria regular expression.
Note title Note Infoblox recommends using regular expressions for refining the membership in device groups. The topic Understanding Device Group Membership Criteria provides the information you need to understand and define regular expressions for device groups.
- If you want the device group to include collections of discovered non-network devices, select Include non-network devices. Leaving this setting unselected prevents non-network devices from occupying valuable licensing space.
- Next to Type, click Extended.
- Rank: Displays the Ranking value as the default sort order. For more information, see Ranking Device Groups.
- Ranking value is used as the default sort order for all group-related tables, with the highest rank shown first. Rank is also used to determine the individual device settings controlling processing for each device.
Polling Frequency: Allows you to slow down or speed up the device polling frequency. For more information, see the following section, Setting Polling Frequency for a Device Group.
For Switch Port data Collection, choose from the following:
- Use Global Settings: Select this to enable the device group to inherit global settings for switch port data collections. To find the global settings, click the Settings icon > Setup > Collection and Groups > Global > Switch Port Management. For more information, see Global Switch Port Management Polling Settings.
- Specify Polling Interval: Overrides the global polling interval with a custom polling interval for the current device group. You can define an interval of 1-60 Minutes or 1-24 Hours in the fields that appear.
- Specify Schedule: Overrides the global scheduled polling setting with a custom schedule for the current device group. Existing schedules may appear in the list or, click Add New Schedule to create a new polling schedule instance. Choose a Recurrence Pattern of Once, Hourly, Daily, Weekly, or Monthly. In all cases, you must choose an Execution Time and select at least one day of the week checkbox.
- Poll Now: Click to execute switch port polling on the device group right after it is created.
Disable: Completely disables switch port polling for the device group.
Note title Note The polling frequency modifier described in the previous step does not affect settings for switch port data collection frequency.
- Activate the processing options for the new Extended group:
...
- Go to Settings icon > Setup > Collection & Groups > Interface Groups side tab.
- Click the Add Group button (below the Interface Groups table). The Add Interface Group dialog appears.
- Type a Name for the interface group. The group name is shown in all group-related displays and reports, so it should be meaningful without being too long.
- Enter a Rank for the interface group. For more information, see Ranking Device Groups for details.
- Type a Membership Criteria expression. For more information, see Understanding Device Group Membership Criteria.
- Activate the processing options for the group.
Performance Statistics Collection: If enabled, NetMRI collects performance data for interfaces in the group. If disabled, the appliance gathers minimal data for interfaces in the group. This setting can be overridden for an individual interface in the Interface Viewer –> Settings icon –> General Settings page.
Frequency: Select the performance statistics collection interval. The default is set as Daily.
