Chapter 7 - SNMP & RMON Management
This chapter describes the Simple Network Management Protocol (SNMP) and Remote
Monitoring (RMON) capabilities of the AGENT-2 S41D switch.
7.1 Overview
RMON is an abbreviation for Remote Monitoring MIB (
M
anagement
I
nformation
B
ase).
RMON is a system that defines how networks can be monitored remotely. This
definition can be found in the Internet Engineering Task Force (IETF) document RFC
2819.
RMON’s typically consist of two components: an RMON probe; and a manage
ment
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 AGENT-2 S41D advanced Ethernet 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 a SNMP network management application with graphical
user interface.
7.2 SNMP Agent and MIB-II (RFC 1213)
The SNMP Agent running on the AGENT-2 S41D switch manager CPU is in charge of:
-
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.
