Remote Monitoring Commands
Remote Monitoring allows a remote device to collect information or respond to specified events on
an independent basis. This switch is an RMON-capable device which can independently perform a
wide range of tasks, significantly reducing network management traffic. It can continuously run
diagnostics and log information on network performance. If an event is triggered, it can
automatically notify the network administrator of a failure and provide historical information about
the event. If it cannot connect to the management agent, it will continue to perform any specified
tasks and pass data back to the management station the next time it is contacted.
This switch supports mini-RMON, which consists of the Statistics, History, Event and Alarm groups.
When RMON is enabled, the system gradually builds up information about its physical interfaces,
storing this information in the relevant RMON database group. A management agent then
periodically communicates with the switch using the SNMP protocol. However, if the switch
encounters a critical event, it can automatically send a trap message to the management agent
which can then respond to the event if so configured.
