- Enter and confirm the password for the NetMRI administrative account. Requirements for the password are listed at the bottom of the screen.
- Click Next Next>.
The administrative account is used by the NetMRI administrator to create user accounts and configure NetMRI. This account 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 administrative account user name is “admin” and cannot be changed. Since this user name is easy to guess, it is essential to assign a strong password to prevent unauthorized users from impersonating the administrator.

- Browse to the location of the NetMRI license file, and then select the license file. The license file ends with the .gpg extension.
- Click Next Next>.
A license is required to use NetMRI for production or evaluation purposes. Each license is keyed to a specific NetMRI serial number and specifies the maximum number of devices and interfaces that NetMRI can monitor, as well as which modules are enabled.
If you have not received a license file or you have misplaced it, you can obtain a license file at http://netmri-license.infoblox.com. When you receive the file, save it in a location you can access from the Setup Wizard.

- Enable or disable auto discovery.
- Click Next Next>.
Enabling automatic discovery means NetMRI will attempt to discover devices on the network using its own discovery methods. There is less configuration required when implementing automatic discovery, but it may take longer to completely discover all the devices you are expecting to be managed.
Disabling automatic discovery means NetMRI will only manage the devices manually input during configuration. Devices known to exist, but not explicitly configured, are not included in any reports or topology data. Configuring NetMRI with discovery disabled may take longer depending on the number of devices on the network.

NetMRI will try site-specific username/passwords, in priority order, when first logging in to a device via a CLI connection (SSH or telnet). Once a password is determined, NetMRI will save it as device-specific information. If there is no site-specific password, NetMRI will try the vendor default credentials in priority order. NetMRI will always use site-specific username/password combinations when trying to determine the new login credentials for a device, and they will not be used for vendor default credential checks.

NetMRI uses SNMP read-only community strings to collect data for its analysis. NetMRI 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, NetMRI 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 you to this condition. If you are using the optional Compliance Module, you will see all vendor default community strings that were able to return SNMP data for a device in the Default Credentials Report.
Manually entered community strings will be used first, in priority order, then the default community strings will be tried in priority order if the Use Vendor Default Community Strings option is enabled in the Settings > Setup section > Collectors and Groups > Global tab > Network Polling panel. That option allows you to disable the use of the vendor default community strings for the 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.

NetMRI uses seed routers to quickly perform network discovery. Definition of seed routers is highly recommended for IPv4 networks and is required for IPv6 networks. Seed routers are also given priority (like static IP definitions) for determining which devices are counted toward NetMRI license limits.
The table lists each defined seed router with its discovery status (as defined in the Network Explorer tab > 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.

Device hints help the NetMRI discovery engine locate specific types of network devices using IP address patterns and DNS name patterns. For instance, if most routers are found at an IP address ending with “.10”, specifying “*.*.*.10” and associating the Router device type for an IP address hint will allow NetMRI to prioritize any discovered devices matching that hint higher in its credential collection queue to help speed discovery. Additionally, this hint is taken into account when NetMRI attempts to determine a device’s type.
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.
Device hints are optional and are only used in helping to speed network discovery and to assist with the determination of device types absent other discovery data.
