RMON is a system defined by the IETF (Internet Engineering Task Force) that allows you to monitor the traffic of LANs or VLANs. RMON is an integrated part of the Switch software agent and continually collects statistics about a LAN segment or VLAN, and transfers the information to a management workstation on request or when a pre-defined threshold is crossed. The workstation does not have to be on the same network as the Switch and can manage the Switch by in-band or out-of-band connections.

RMON
Using the RMON capabilities of a Switch allows you to improve your
network efficiency and reduce the load on your network.
This section explains more about RMON. It covers the following topics:

What is RMON?

Benefits of RMON
■
RMON and the Switch
What is RMON?
RMON is a system defined by the IETF (Internet Engineering Task Force)
that allows you to monitor the traffic of LANs or VLANs.
RMON is an integrated part of the Switch software agent and continually
collects statistics about a LAN segment or VLAN, and transfers the
information to a management workstation on request or when a
pre-defined threshold is crossed. The workstation does not have to be on
the same network as the Switch and can manage the Switch by in-band
or out-of-band connections.
The RMON Groups
The IETF define groups of Ethernet RMON statistics. This section describes
the four groups supported by the Switch, and details how you can use
them.
