Advanced Management

Ethernet Statistics Group

This group contains statistics measured on each port of the IntraChassis 9000. These are cumulative counters which start at zero each time the IntraChassis 9000 is reset. The Statistics Group is automatically implemented by the IntraChassis 9000.

Ethernet History Group

This group records periodic statistical samples from ports on the IntraChassis 9000 and stores them for later retrieval. A network manager can use the data to analyze how network traffic has varied over a period of time.

Alarm Group

This group takes periodic statistical samples from variables in the IntraChassis 9000 and compares them to previously configured thresholds. If the monitored variable crosses a threshold, an event is generated.

Event Group

This group controls the generation and notification of events from the IntraChassis 9000. The Alarm and Event groups together allow the network manager to configure RMON so that if a particular statistic such as the number of bad frames goes higher than a certain level, the IntraChassis 9000 will send a trap to its configured trap receivers, notifying the manager of the event. For information on configuring trap receivers, see “SNMP Configuration” in Chapter 3.

The IntraChassis 9000 switches provide control of the RMON groups only through SNMP. Please see the documentation for your SNMP management application for information.

For more information about RMON, please see RFC1757, “Remote Network Monitoring Management Information Base”, available from the FTP site listed in Appendix A.

Security

There are three security options you can use on ports of the IntraChassis 9000. These are duplicated IP detection/trapping, station movement trapping, and new node trapping.
