Remote Monitoring
– 392 –
Remote Monitoring
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.
The 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.
Configuring
RMON Alarms
Use the Administration > RMON (Configure Global - Add - Alarm) page to define
specific criteria that will generate response events. Alarms can be set to test data
over any specified time interval, and can monitor absolute or changing values (such
as a statistical counter reaching a specific value, or a statistic changing by a certain
amount over the set interval). Alarms can be set to respond to rising or falling
thresholds. (However, note that after an alarm is triggered it will not be triggered
again until the statistical value crosses the opposite bounding threshold and then
back across the trigger threshold.
Command Usage
◆ If an alarm is already defined for an index, the entry must be deleted before any
changes can be made.
Parameters
These parameters are displayed:
◆ Index – Index to this entry. (Range: 1-65535)
◆ Variable – The object identifier of the MIB variable to be sampled. Only
variables of the type etherStatsEntry.n.n may be sampled.
Note that etherStatsEntry.n uniquely defines the MIB variable, and
etherStatsEntry.n.n defines the MIB variable, plus the etherStatsIndex. For
example, 1.3.6.1.2.1.16.1.1.1.6.1 denotes etherStatsBroadcastPkts, plus the
etherStatsIndex of 1.
◆ Interval – The polling interval. (Range: 1-31622400 seconds)
