7: SNMP & RMON Management
This chapter describes the Xpress-Pro SW 94000 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 Xpress-Pro SW 94000 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.
SNMP Agent and MIB-2 (RFC 1213)
The SNMP Agent running on the Xpress-Pro SW 94000 switch manager CPU is
responsible for:
Retrieving MIB counters from various layers of software modules according to the SNMP
GET/GET NEXT frame messages.
Setting MIB variables according to the SNMP SET frame message.
Generating an SNMP TRAP frame message to the Network Management Station if the
threshold of a certain MIB counter is reached or if other trap conditions (such as the
following) are met:
Warm start
Cold start
