A primary application for NetMRI is discovering the network and all its infrastructure devices.
...
- Your currently managed network, with its current discovery settings, is managed through a new network view named after the previously defined network name. No further configuration is necessary for continued network management but changes can be made at any time. For more information, see Configuring Network Views.
- Existing discovery settings, such as CIDR discovery ranges, are automatically assigned to the network view used for the managed network.
- Your SCAN port for your appliance (or appliances, in the case of Operations Center deployments using Collectors) will automatically be assigned to the network view that is used for your present managed network. This port will be named LAN1. For more information, see Configuring Scan Interfaces.
- Depending on your appliance, a second LAN2 port is made available for further network connections.
- Your MGMT port will continue to operate as the appliance's Web management interface.
- All active Ethernet interfaces on your appliance(s), including the MGMT port, support Ethernet 802.1Q encapsulation for virtual scan interfaces. For more information, see Configuring Virtual Scan Interfaces.
- If VRF-aware devices exist on your managed network, System Health banner messages will notify you about unassigned VRFs. To enable full network discovery and control for each virtual network, these networks need to be mapped to virtual scan interfaces. For more information, see 30802054Mapping Virtual Networks to Network Views and Configuring Virtual Scan Interfaces.
Existing Operations Center deployments will see the following changes:

Viewing Device Discovery Status and Re-Discovering a DeviceTo view discovery status for any device, open the Device Viewer by navigating to Network Explorer -> Discovery and clicking a device link, or Device Viewer -> Settings & Status –> Management Status. You will see the Management Status for the device. This is an important block of information that immediately describes the effectiveness of communications to the device by NetMRI.
