Infoblox recommends reading the topics in About Network Discovery before running the Setup Wizard for the first time. |
The Setup Wizard (Settings icon –> icon > Setup –> > Setup Wizard) provides a multistep process for installing and configuring NetMRI. As shown in the table below, steps in the Wizard depend on whether it is run during installation or from Settings, and whether you choose to use Auto Discovery.
...
The primary administrative account is used by the NetMRI administrator to create user accounts and configure NetMRI. This account's user name and password are also required to access the administrative shell (a command-line interface). Other NetMRI users do not have the special privileges available to the administrator. The administrator account is the "superuser" account in the NetMRI appliance.

This step is present during the initial NetMRI setup. It does not appear after successfully configuring NetMRI and running the setup wizard via the Settings icon –> icon > Setup –> > Setup Wizard, or installing the license using the Admin Shell. Subsequent license installations can be carried out by going to Settings icon –> Setup –> clicking the Settings icon > Setup > Settings Summary and clicking the Install link above License Configuration. |

- 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 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.
...
- Specify IP addresses that you want NetMRI to manage.
- Click New, enter the new IP address in the IP Address field (subnet is not necessary), and choose the Discovery Mode. For the first network you discover, use the Include in Discovery selection.
- Ensure that the network view chosen in the Wizard step Setup Wizard: Discovery Ranges is selected from the Network View drop-down list. For example, you may use the Network 1 network view.
- Click Add.
- To edit an item, select an entry and click Edit. Change the value in the IP Address field above the table or change the Discovery Mode (by default it is set to Include in Discovery), then click Save.
- To delete an item, select an entry, 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.

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.
...
Manually entered community strings are used first, in priority order, then the default community strings are tried in priority order if the Use Vendor Default Community Strings option is enabled in the Settings icon –> icon > Setup –> > Collection and Groups –> > Global tab –> > Network Polling panel. Here, you can disable the use of the vendor default community strings for determination of which strings NetMRI can use. This is typically done in installations having tight security setups that have removed all vendor defaults from their installation. Note that this option does not prevent the vendor default from running.
...

For VRF-aware Juniper devices, to ensure device reachability for VRF configurations, prefix a second community string using the "@" character, such as @snmpnet, along with the normal community string (for example, snmpnet) you define for the device. For more information, see Vendor-Specific Requirements for Virtual Device Discovery. |

The table lists each defined seed router with its discovery status (as defined in the Network Explorer –> > Discovery tab). By reviewing the discovery status for each seed router you can determine whether NetMRI should be able to discover the network successfully, or if there are possible configuration errors preventing network discovery, without having to wait to see what NetMRI finds.
- 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 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.
- Click Next.
...
Valid IP address patterns are either the numeric values of the octet , or an asterisk for any number of octets in the IP address. For device name matches, valid DNS characters and the asterisk character are valid definitions. For instance, rtr will match any device name with "rtr" in its definition.
...
- Study the summary information in on this final Wizard page before finishing the setup. For any item flagged as a possible configuration problem, click the Edit link to go directly to the corresponding step in the wizard to make changes. After making changes, return to the Summary step.
- Click Finish.
