Chapter 1 Introduction This chapter describes the SPECTRUM Management Module software for the Novell LANtern Network Monitor and LANtern Network Monitoring Module (NMM) for the Cabletron Systems MMAC. It also provides the Model Type Name assigned to the LANtern in SPECTRUM. The Model Type Name refers to the template used to specify device attributes, actions, and associations for device models in SPECTRUM.
LANtern Management Module The management module software allows a network administrator to model, monitor, and manage individual devices or groups of devices on a network. The LANtern Network Monitor/LANtern NMM Management Module contains all the information necessary to manage Novell LANtern Network Monitor and LANtern NMM devices using SPECTRUM, including a software emulation of the actual LANtern Network Monitor and LANtern NMM device attributes and functionality.

LANtern Management Module Introduction 1-4 Novell LANtern Network Monitor Management Module Guide
Chapter 2 Device View The Device View shows a physical representation of the LANtern NMM installed in a Cabletron MMAC hub chassis and provides menu access to the LANtern NMM generic views. These generic views allow you to access network configuration information, as well as traffic flow and error data for your Novell LANtern Network Monitor. This chapter describes how to use the Device View to view MIMs, access SPECTRUM generic views, and monitor the performance of the LANtern or LANtern MIM.
Configuring the LANtern NMM in an IRM or IRBM NOTE This path (/CsDevice.pib) is set in your .Xdefaults or appdefaults/spectrum files. 2. The LANtern NMM model type designation contained in the CsDevice.pib file points to the MIM_LANtern.D3P () perspective file, which contains: • The image (.csi) filename for the LANtern NMM. The .csi file is located in a directory defined by your imagepath (). • The position coordinates for each LED on the LANtern NMM. 3.
IRM2 or IRBM Hub Device Views 5. Enter the IP address of the LANtern NMM device. If you have already created the LANtern NMM as a stand alone icon, enter the same IP address here. NOTE Cabletron recommends assigning a unique model name to the LANtern NMM installed in the hub chassis to easily differentiate it from an independent LANtern NMM icon (NA_Nov_LANMIM) with the same assigned IP address.. 6. Select Close/Update from the File menu in the LANtern NMM Configuration View. 7.
IRM2 or IRBM Hub Device Views System UpTime The time the hub has been active without failure displayed in the following format: days+hours:minutes:seconds A condition status banner surrounding this information displays the condition status color for the hub containing the LANtern NMM. Refer to Table 4-2 for definitions of condition status colors.

The IP Address Checking status field in the MAC to IP Address Table and the Duplicate Checking status field in the Duplicate IP Table will both read Enabled.
Chapter 4 Event and Alarm Messages What is in this Chapter This chapter describes the events and alarms that Novell LANtern devices generate. Events and alarms originate as unsolicited Simple Network Management Protocol (SNMP) messages known as traps. SPECTRUM translates these traps as events and displays them in the Event Log. If SPECTRUM maps an event to an alarm, the event will also appear in the Alarm View as an alarm.
Events and Alarms Table 4-1. Events and Alarms Event Message 00010007 Probable Cause Message 00010007 A LANtern network monitor {v} name {v}, The model’s Contact Status attribute has has reported a Cable Failure.

Chapter 5 Application View The Application View contains basic network monitoring information for the LANtern Network Monitor or LANtern NMM. Application View Buttons The Application View contains seven buttons that lead to the Remote PING utility and the Novell LANtern and LANtern NMM tables, as follows: Remote PING The Remote PING button accesses the Remote PING View. Remote PING allows you to ping a device not on your network segment through the LANtern or LANtern NMM monitoring that segment.
Application View Buttons MAC to IP Address Table The MAC to IP Address Table button accesses the MAC to IP Address Table. This table cross-references device IP addresses to device MAC (Ethernet) addresses on your network segment. Duplicate IP Table The Duplicate IP Table button accesses the Duplicate IP Table. This table lists any stations that the Novell LANtern or LANtern NMM has detected with a duplicate IP address on your network segment.
Application View Buttons for that statistic, and delete the station from the Destination-Source Table list. • Access the InDirect LANtern Model button (refer to Chapter 6 for detailed information on the InDirect LANtern Model button). Destination-Source Table The Destination-Source Table button accesses the Destination-Source Table.
Application View Buttons Organizing Ethernet Addresses Organizing Ethernet Addresses As a means of organizing device Ethernet addresses, the Application View includes a field for creating a file to store specific device addresses. As the LANtern or LANtern NMM monitors devices on a network segment and adds their addresses to a table, the tables can become extremely lengthy. By default, the first 500 addresses in any table are displayed.
Application View Buttons The Update Timing Interval Sort You can sort columns in a table incrementally using the Sort button as follows: 1. Single-click on the particular column label. The Sort button appears at the top of the table. 2. Single-click on the Sort button to sort that particular column. Ethernet (hex) device addresses are sorted in ascending order. Statistical information is sorted in descending order. Columns that have been sorted will remain sorted as the table is updated.
The Indirect Lantern Icon 3. Select Close/Update from the File menu. 4. Click OK at the Save Updated Information? prompt. If you select Automatic, the table is updated according to the specified update timing interval. If you select Manual, an Update button appears on each Application View table. To update the table, single-click on the button.
Creating the Indirect LANtern Icon Placing the Indirect LANtern Icon into a SPECTRUM View Location Enter the physical location of the device modeled with the InDirect LANtern icon (i.e., building, site, room, etc.). Contact Enter the name of the individual responsible for maintaining the device modeled by the InDirect LANtern icon. Polling Interval The time interval, in seconds, for polling any attributes that have been flagged as “POLLED.” The default Polling Interval value is 60 seconds.
Creating the Indirect LANtern Icon Placing the Indirect LANtern Icon into a SPECTRUM View NOTE Application View 5-8 The SPECTRUM views to which an InDirect LANtern icon can be added, are identical to those available for the corresponding LANtern Network Monitor or LANtern NMM model type icons (Location, Topology, or Off-Page Reference).
Appendix A Statistical Reports This appendix describes the Report Format (.rib) files included with the Novell LANtern management module. These .rib files allow you to generate reports which monitor network activity and network entity relations. The network administrator sets up reports for each model type (not each individual icon) to record network activity and device performance over a specified period.
