logs those events to the log. RMON can also send traps to the destination address configured by the
management workstation. You can also use RMON to trigger a system reboot.
Management Workstation
A management workstation communicates with the RMON agent and collects the statistics from it. The
workstation does not have to be on the same network as the RMON agent and can manage the agent by
in-band or out-of-band connections.
If you enable RMON on the switch, you can use a management workstation to review port statistics and
port history, no configuration of the management workstation is necessary. However, you must use a
management workstation to configure the alarm and event entries.
Supported RMON Groups of the Switch
The IETF defines nine groups of Ethernet RMON statistics. The switch supports the following four of
these groups, as defined in RFC 1757:
●
Statistics
●
History
●
Alarms
●
Events
The switch also supports the following parameters for configuring the RMON agent and the trap
destination table, as defined in RFC 2021:
●
probeCapabilities
●
probeSoftwareRev
●
probeHardwareRev
●
probeDateTime
●
probeResetControl
●
trapDestTable
The following sections describe the supported groups, the RMON probe configuration parameters, and
the trap destination parameter in greater detail.
Statistics
The RMON Ethernet Statistics group provides traffic and error statistics showing packets, bytes,
broadcasts, multicasts, and errors on an Ethernet port.
Information from the Statistics group is used to detect changes in traffic and error patterns in critical
areas of the network.
History
The History group provides historical views of network performance by taking periodic samples of the
counters supplied by the Statistics group. The group features user-defined sample intervals and bucket
counters for complete customization of trend analysis.
