Infoblox recommends enabling automatic discovery during the Setup Wizard. |
With the automatic discovery, NetMRI attempts to discover devices on the network using SNMP and terminal command-line discovery methods. Less configuration is required by using automatic discovery, but it may take longer to completely discover all the devices you expect to be detected and managed.
...
- Enable or disable auto discovery.
- Click Next.

You can add new IP address ranges and seed routers at any time after initial NetMRI setup. IPv4 and IPv6 are supported. For more in-depth information, see the Configuring Discovery Ranges Configuring Discovery Ranges topic. |
Discovery ranges define the scope of the network that NetMRI explores by defining CIDR address blocks, IP address ranges and IP address wildcards. NetMRI limits its network exploration to the set of ranges defined in this tab. You can also exclude values and ranges from the Discovery process and hence from monitoring by NetMRI.
- A CIDR address block is defined by a network address and bit mask (for example 192.168.1.0/24).
- An IP address range defines a start and ending IP address. For instance, you could define 192.168.1.0 as the start of the IP range and 192.168.1.255 as the end of the IP range.
- An IP address wildcard pattern defines a single IP address range using a wildcard character or range for a specific set of octets. For example, you could define either 192.168.1.* or 192.168.1.0-255 as the IP address wildcard pattern. An IP address wildcard pattern can substitute an asterisk or range for any single octet in the definition.
- A desired set of values can also be imported from a *.CSV file.
- Every discovery range must be associated with a network view. For more information, see Configuring Network Configuring Network Views.
Ranges included in discovery indicate that any device found matching that range is discovered and managed by NetMRI. Ranges excluded for discovery indicate that any device found matching that range is excluded from discovery. Ranges marked Exclude from Management indicate that any device found matching that range is discovered, but NetMRI will not manage/collect data from the device.

NetMRI uses SNMP read-only community strings to collect data for analysis. The system is pre-configured with several commonly used community strings taken from the list of default community strings configured by the device vendor at delivery time. If the community strings provided during NetMRI installation do not work for a given device, the system tries well-known vendor defaults. If a default community string works for the device, NetMRI begins normal SNMP processing, and the "Weak Community String" issue is fired to alert to this condition.

Definition of seed routers is highly recommended for IPv4 networks and is required for IPv6 networks. For more in-depth information, see the Adding Seed Routers Adding Seed Routers topic. |
NetMRI uses seed routers to quickly perform network discovery. Seed routers are also given priority (like static IP definitions) for determining which devices are counted toward NetMRI's license limits.
...
- Enter IP addresses for seed routers.
- Click New, enter the value in the Seed Router IP Address field, then click Add.
- Ensure that the network view chosen in the Wizard step Setup Wizard: Discovery Ranges is is selected from the Network View drop-down list. For example, you may use the Network 1 network view.
- Click Add or Add & Discover.
- To edit an item, select the item, click Edit, change the fields above the table, then click Save.
- To force immediate discovery, click Add & Discover.
- To delete an item, select the item, click Delete, then confirm the deletion.
- To import discovery setting data, click Import. In the dialog, click Browse to select the CSV file, then click Import. See Discovery Settings Import Formats for information on import file syntax. The imported file data are applied as a set of one or more Seed Routers. Ensure that the values are correct before importing.
