RMON
Overview
RMON stands for remote monitoring. It is a standard for moni-
toring and reporting network activity using remote monitors.
You can use RMON via the switch’s Local Management Inter-
face or via any SNMP-based network management software that
supports RMON.
A typical RMON setup consists of two components:
❏ The RMON probe — a device or software agent
that continually collects statistics about a LAN
segment and transfers the information to a man-
agement workstation (either on request or when
a pre-defined threshold is crossed).
❏ The management workstation — a network
station that communicates with the RMON probe
and collects statistics from it. The workstation
does not have to be on the same network as the
probe and can manage the probe by in-band or
out-of-band connections.
Benefits of
RMON
Some of the benefits of using RMON are:
❏ Impr oved ef ficiency — you can remain at one
workstation and collect information from widely
dispersed LAN segments.
❏ Pr oductive management — if configured cor-
rectly, RMON probes can deliver information
before problems occur.
❏ Reduces load on the network and the man-
agement station — an RMON probe looks at
the network on behalf of the network manage-
ment station without affecting the characteristics
and performance of the network.
