Creating IndirectRMON Models
This chapter describes how to set up IndirectRMON models.
IndirectRMON Models
The IndirectRMON Model Type was designed to take advantage of additional
network monitoring possibilities made available by data contained in the Host
Table.
A number of hosts on the network, whose MAC addresses are in the Host
Table, may not be using SNMP as a management protocol or otherwise may
not be supported by SPECTRUM, yet their traffic statistics are visible to
RMON. The IndirectRMON model, which you can create, accesses the RMON
Host Table to acquire these management statistics which are not available in
the normal fashion of polling. Therefore, this model provides a means to
present status and performance statistics for such devices in the normal
fashion of a SPECTRUM model.
This model offers another advantage in that it provides current performance
statistics on any host without the need to access the RMON Host Table.
Also, by modeling the device by MAC address only, the modeling method
provides the convenience of not having to locate or identify the actual device
type and IP address. In fact, the device may not even have an IP address.
NOTE
Before you use the IndirectRMON Model Type, consider using the Generic
SNMP Device model type (GnSNMPDev) provided by SPECTRUM for
modeling any SNMP capable device for which a specific model type is
unavailable. To use GnSNMPDev, however, you must know the device’s IP
address.
