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.
Since the LANtern NMM (NA_Nov_LANMIM) is installed in a Cabletron hub
chassis, it appears in the Device View for that Cabletron hub. The Novell
LANtern Network Monitor (NA_Nov_LANtern) does not have a Device View.
Depending on the type of Cabletron hub containing the LANtern NMM, the
Device View appears slightly different. The Cabletron hub categories are as
follows:
IRM2, IRM3, and IRBM
IRM (both SNMP and Cabletron proprietary protocol)
Device View Perspective
The Device View for a Cabletron hub gives an actual representation of the hub
configuration. If the configuration changes (e.g., a LANtern NMM is inserted
into or pulled from the hub), a corresponding change is displayed in the hub’s
Device View after the hub’s next poll cycle.
The Device View represents the hub’s physical configuration by executing the
following procedures:
1. The Device View reads a perspective file called CsDevice.pib, which
contains a list of designations for all model types supported in
SPECTRUM, along with their appropriate background image files.
