RMON
Using the Remote Monitoring (RMON) capabilities of the switch allows network administrators to
improve system efficiency and reduce the load on the network.
The following sections explain more about the RMON concept and the RMON features supported by
the switch.
NOTE
You can only use the RMON features of the system if you have an RMON management application and have enabled
RMON on the switch.
About RMON
RMON is the common abbreviation for the Remote Monitoring Management Information Base (MIB)
system defined by the Internet Engineering Task Force (IETF) documents RFC 1757 and RFC 2021,
which allows you to monitor LANs remotely.
A typical RMON setup consists of the following two components:
●
RMON agent
●
Management workstation
RMON Agent
An RMON agent is an intelligent software agent that continually monitors port statistics and system
variables. The agent transfers the information to a management workstation on request, or when a
predefined threshold is crossed.
Information collected by RMON includes Ethernet port statistics and history and the software version
and hardware revision of the device. RMON generates alarms when threshold levels are met and then
