SNMP & RMON Management
This chapter describes the switch’s Simple Network Management
Protocol (SNMP) and Remote Monitoring (RMON) capabilities.
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.
