RMON Models
distinct network segments, which are then internally bridged or routed within
the EMME.
An RMON agent running on a network device collects and maintains RMON
data for each interface on the device. The RMON Management Module
supports three types of models to represent the RMON agent and its
supported applications and interfaces. When you use SPECTRUM to model a
device that supports RMON, RMON models are created automatically within
SPECTRUM’s Application View. The following sections provide a description
of these models and their relationship to each other.
An RMONApp model accesses and presents RMON data from all network
interfaces supported by a device. An RMON probe model accesses and
presents RMON data specific to one interface. Depending on your network,
the probe models are specific to Ethernet or Token Ring.
Icons for the RMONApp model and RMON probe model appear in
SPECTRUM’s Application View. Icons are graphical representations of the
models that exist within the SPECTRUM database. From the icons, you can
access SPECTRUM subviews that provide detailed RMON data collected on
the network interfaces that the models represent.
Figure 1-1 shows a portion of an EMME’s application view, showing the
RMONApp model and probe models for two of the four interfaces on the
device.
