greater than this threshold level, an alarm event is triggered. The parameter’s
range is 1 to 2147483647.
•
Falling Threshold: This parameter specifies a specific value or threshold level of
the monitored statistic. When the value of the monitored statistic becomes less
than this threshold level, an alarm
event is triggered. The parameter’s range is
1 to 2147483647.
•
Rising Event: This parameter specifies the event index for the rising threshold.
Its range is 1 to 65535. This field is mandatory and must match an Event Index
that you previously entered in “Events”.
•

History
System > RMON > History List
RMON histories are snapshots of port statistics. They are taken by the switch at
predefined intervals and can be used to identify trends or patterns in the numbers or
types of ingress packets on the ports on the switch. The snapshots can be viewed with
your SNMP NMS software with the history group of the RMON portion of the MIB tree.
A history group is divided into buckets. Each bucket stores one snapshot of statistics of a
port. A group can have from 1 to 50 buckets. The more buckets in a group, the more
snapshots it can store.
1. Log into your switch management page (see “ Access your switch management page ”
on page 5).
2. Click on System , click on RMON, and click on History .
3. Review the settings.
•
Index: This parameter specifies the ID number of the new group. The range is 1
to 65535.
•
Sample Port: This parameter specifies the port where you want to monitor the
statistical information of the Ethernet traffic.
•
Buckets Requested: This parameter defines the number of snapshots of the
statistics for the port. Each bucket can store one snapshot of RMON statistics.
Different ports can have different numbers of buckets. The range is 1 to 50
buckets.
•
Interval: This parameter specifies how frequently the switch takes snapshots of
the port’s statist ics. The range is 1 to 3600 seconds (1 hour). For example, if
you want the switch to take one snapshot every minute on a port, you specify
an interval of sixty seconds.
•
Owner: This parameter is used to identify the person who created an entry. It is
primarily intended for switches that are managed by more than one person,
and is an optional field.
