1. In the Detail Columns field of the Add Command Script Issue dialog (see above), enter IP Address, string.
2. In the Issue-Details section of the CCS script, add "IP Address" $ipaddress (including the quotation marks). The resulting CCS issue contains the IP address with a hyperlink to the Device Viewer.

Custom issue help files provide NetMRI users with organization-specific information for individual issues. All issue help files associated with an issue are accessed via hyperlinks in the See Also section of the Issues Viewer. Multiple help files can be associated with an issue.

Help files can be stored in any format (e.g., .pdf, .doc, .txt, .jpg, etc.) that can be rendered by the web browser. Also, help files can be written in any language supported by NetMRI, enabling the user to view them in the language defined for the console.

• The Inventory tab provides basic information about all active devices, interfaces, operating systems and models in the network, including virtual devices, which are instances of virtual routers, virtual switches and other types that are supported by selected devices from some networked system vendors;
• The Summaries tab lists routes, subnets, VLANs, HSRPs/VRRPs, route targets, network views, VRFs and ports in the network;
• The Topology tab provides an interactive viewer in which you can visually explore your network’s topology and interconnectivity;
• The Discovery tab provides detailed information about NetMRI’s discovery processes, including the ability to affect Discovery settings for individual devices, perform/repeat Discovery on a single device, set licensing for a managed device and remove a device from NetMRI management. (For more information on device-related Discovery functions, see the section Viewing Device Discovery Status and Re-Discovering a Device);
• Switch Port Management is a key feature set for compiling, monitoring and controlling the devices, ports and end hosts throughout an enterprise’s switched Ethernet network. Consult the topics under Switch Port Management for many more details.

...

Note: If you know exactly what you are seeking, try typing a few characters in the FindIT search box (upper right corner of the main NetMRI page).

...

The Device Viewer is not limited to this information. Seven categories of detailed information are provided by the Device Viewer for the displayed network entity. For more, sees under Inspecting Devices in the Network.

Viewing Date-Based Data Sets

...

Each individual virtual device context appears in the Device Viewer, in the NetworkExplorer–>Inventory page, and in other locations of the NetMRI UI. NetMRI treats virtual device contexts identically to conventional routers, switches and firewall appliances, including the ability to send commands, schedule and execute jobs, display running configurations, view change histories and issues reported from the virtual device, apply compliance policies, run traces and SNMP walks, and many other operations.

NetMRI supports detection and management of the following

...

• To list devices comprising the route: Click a route in the left panel. The center panel refreshes to show the device reporting the route, the route's interface from which it was reported, the Network View for the management IP of the device reporting the route, and the route's Next Hop. The list also shows each device's Route Distinguisher. This feature can be helpful in tracing a path, and can be helpful with Path Analysis.
• To view detailed data for a device: Click the IP address hyperlink in the center panel. The Device Viewer opens.

...

• The global Network View, where you can view different parts of the network based on the network type: the aggregate, which shows all active links of every type; Link Discovery Protocols, Serial Links and Switch Forwarding, which shows only Ethernet-switched connections throughout the network;
• The L2 nHop Network Topology, showing the Layer 2 switching paths of the network;
• The L3 nHop Network Topology, showing the Layer 3 switching/routing paths of the network;
• The L2/L3 Most Likely Path Network Topology, indicating the spanning tree paths preferred by switched network traffic in the network;
• The L3 Most Likely Path Network Topology, indicating the routed paths preferred by most packet flows in the network;
• The VLAN Network Topology, mapping the paths of VLANs throughout the network;

...

Note: The Most Likely Path and Path Analysis options require option requires the selection of a source network view.

...

In all topology types (L2 nHop Network Topology, L3 nHop Network Topology, and so on) clicking on a device in the left-pane list displays a Hop Count selector. This selector changes its fields based on the protocol. (The figure to the left shows an L3 n Hop selector, in which you can choose a Hop Count from 1 to 4, and the protocol to view. The protocol you choose may or may not be active for the current device.The Hop Count selector does not apply to the Path Analysis feature.

After you generate a graph, follow the topics below to change and enhance the graph.

...

L3 n Hop shows all active devices that can be reached from a selected starting device in the network through a chosen number of routed Level 3 connections. In the resulting graph, the name of the starting device is highlighted in green. Devices that cannot be reached, or that are farther away than the Hop Count are not shown in the resulting view. The information conveyed here can be considered a superset of the Path Analysis feature, which shows the preferred L3 routed path from the selected stating device to a defined destination device.

1. In the left panel, click L3 n Hop.
2. In the left panel, click the row containing the starting device.
3. In the L3 n Hop dialog, select a Hop Count and a Protocol.
4. Click OK.

...

In the resulting graph, the name of the starting device is highlighted in green, and the name of the ending device is highlighted in red.

If a device continues to appear in collected data, NetMRI will re-list the device unless you choose to exclude the device from discovery when it is deleted.

To un-manage devices, do the following:
