Configuring and Enabling RMON
The Professional RMON groups are shown in the table below.
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 GSR. Creating default control tables essentially configures data
collection for every port on the GSR 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.
