Chapter 17: RMON Configuration Guide
If you choose to create default control tables, entries are created in the control tables for
each port on the IA for the following groups:
Lite groups:
Standard groups:
Professional groups:
A row in the control table is created for each port on the IA, with the owner set to monitor.
If you want, you can change the owner by using the appropriate rmon command. See
"Configuring RMON Groups" on page 254
group.
Note:
Control tables other than the default control tables must be configured with CLI
commands, as described in
Using RMON
RMON on the IA allows you to analyze network traffic patterns, set up alarms to detect
potential problems before they turn into real congestive situations, identify heavy
network users to assess their possible candidacy for moves to dedicated or higher-speed
ports, and analyze traffic patterns to facilitate more long-term network planning.
RMON 1 provides Layer-2 information. Traffic flowing through the IA's Layer-2 ASIC is
collected by RMON 1 groups. RMON 2 in the IA provides Layer-3 traffic information for
IP protocols. Traffic flowing through the IA's Layer-3 ASIC is collected by RMON 2
groups. The IA's RMON 2 protocol directory contains over 500 protocols that can be
decoded for UDP and TCP ports. You can use RMON to see the kinds of protocol traffic
being received on a given port.
