Manageable 8/9-Port Switch

SNMP & RMON MANAGEMENT

OVERVIEW

SNMP AGENT AND MIB-2 (RFC 1213)

This section describes the switch’s Simple Network Management Protocol (SNMP) and

Remote Monitoring (RMON) capabilities.

The SNMP Agent running on the 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 fol-

lowing) are met:

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 worksta-

tion:

- 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 net-

work management application with graphical user interface.
