RMON Support
Remote monitoring (RMON) lets a management system remotely monitor and
report network activity. Of the nine groups defined by RMON in RFC1757, the
2824 hub implements four, including Statistics, History, Alarm, and Event.
RMON is designed to supplement the management information from SNMP. In
particular, RMON provides functions for getting information about the
operation and performance of entire networks or of subnetworks in an
internetwork.
Statistics Group
The statistics group, as defined in RFC1757, consists of the Ethernet Statistics
Table (etherStatsTable). This table contains objects that report normal traffic
and error counts. It can evaluate the network load on a data source. Statistics
monitors are listed below.
etherStatsDropEvents etherStatsOctets

etherStatsPkts256to511Octets etherStatsPkts512to1023Octets

RMON collects statistics for any data source and can monitor multiple
data sources.
