STATUS MONITORING AND 
STATISTICS
This chapter contains details of the Remote Monitoring (RMON) feature 
that assists you with status monitoring and statistics.
For detailed descriptions of the Web interface operations and the 
Command Line Interface (CLI) commands that you require to manage the 
Switch please refer to the Management Interface Reference Guide 
supplied in HTML format on the CD-ROM that accompanies your Switch.
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.
