RMON
Using the RMON (Remote Monitoring) capabilities of
your Switch allows network administrators to
improve their efficiency and reduce the load on their
network.
The following sections explain more about the
RMON concept and the RMON features supported
by the Switch.
You can only use the RMON features of the Switch
if you have an RMON management application,
such as the RMON application supplied with
3Com’s Transcend Enterprise Manager.
What is RMON?
RMON is the common abbreviation for the Remote
Monitoring MIB (Management Information Base), a
system defined by the IETF documents RFC 1271
and RFC 1757, which allows you to monitor LANs
remotely.
A typical RMON setup consists of two components:
■
The RMON probe
— An intelligent,
remotely-controlled device or software agent
that 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 management workstation
— Communi-
cates with the RMON probe and collects the sta-
tistics 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.
