ONITORING
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.

LARMS
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.

If an alarm is already defined for an index, the entry must be deleted
before any changes can be made.

ARAMETERS
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.
