6. SNMP & RMON Management
This chapter describes the switch’s Simple Network
Management Protocol (SNMP) and Remote Monitoring (RMON)
capabilities.
6.1 Overview
RMON is an abbreviation for the Remote Monitoring MIB
(Management Information Base). RMON is a system defined by
the Internet Engineering Task Force (IETF) document RFC 1757,
which defines how networks can be monitored remotely.
RMONs typically consist of two components: an RMON probe
and a management workstation:
The RMON probe is an intelligent device or software agent
that continually collects statistics about a LAN segment or
VLAN. The RMON probe transfers the collected data to a
management workstation on request or when a pre-defined
threshold is reached.
The management workstation collects the statistics that the
RMON probe gathers. The workstation can reside on the
same network as the probe, or it can have an in-band or
out-of-band connection to the probe.
The switch provides RMON capabilities that allow network
administrators to set parameters and view statistical counters
defined in MIB-II, Bridge MIB, and RMON MIB. RMON activities
are performed at a Network Management Station running an
SNMP network management application with graphical user
interface.
