Chapter 21: RMON Configuration Guide
Control Tables
Many RMON groups contain both control and data tables. Control tables specify what
statistics are to be collected. For example, you can specify the port for which statistics are
to be collected and the owner (name, phone, or IP address) for that port. You can change
many of the entries in a control table with
rmon commands. Data tables contain the
collected statistics. You cannot change any of the entries in a data table; you can only view
the data.
When you specify the Lite, Standard, or Professional RMON groups, you have the option
of creating default control tables. A default control table creates a control table entry for
every port on the SSR. Creating default control tables essentially configures data
collection for every port on the SSR for certain RMON groups. If you do not want this, you
can choose not to create the default control tables and then configure the appropriate
control tables for the data you wish to collect. Even if you use the default control tables,
you can always use the
rmon commands to modify control table entries.
If you choose to create default control tables, entries are created in the control tables for
each port on the SSR for the following groups:
Lite groups: Etherstats
History
Standard groups: Host
Matrix
Professional groups: Protocol Distribution
Address Map
Application Layer/Network Layer Host
Application Layer/Network Layer Matrix
Application Layer
Matrix (and Top N) Monitors traffic at the application layer for protocols defined
in the Protocol Directory. Top N gathers the top n application
layer matrix entries.
Network Layer Matrix
(and Top N) Monitors traffic at the network layer for protocols defined in
the Protocol Directory. Top N gathers the top n network
layer matrix entries.
Address Map Records MAC address to network address bindings
discovered for specified ports.
User History Records historical data on user-defined statistics.
