SmartSwitch Router User Reference Manual 303Chapter 21: RMON Configuration GuideControl TablesMany RMON groups contain both control and data tables. Control tables specify whatstatistics are to be collected. For example, you can specify the port for which statistics areto be collected and the owner (name, phone, or IP address) for that port. You can changemany of the entries in a control table with rmon commands. Data tables contain thecollected statistics. You cannot change any of the entries in a data table; you can only viewthe data.When you specify the Lite, Standard, or Professional RMON groups, you have the optionof creating default control tables. A default control table creates a control table entry forevery port on the SSR. Creating default control tables essentially configures datacollection for every port on the SSR for certain RMON groups. If you do not want this, youcan choose not to create the default control tables and then configure the appropriatecontrol 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 foreach port on the SSR for the following groups:Lite groups: EtherstatsHistoryStandard groups: HostMatrixProfessional groups: Protocol DistributionAddress MapApplication Layer/Network Layer HostApplication Layer/Network Layer MatrixApplication LayerMatrix (and Top N)Monitors traffic at the application layer for protocols definedin the Protocol Directory.
