5.6.15.5 Ether-Like Port (Device Data Collection Tab)
The history of statistical data is collected what are called buckets, which collect a certain amount of data over a specific time.
By recording and then observing these buckets, users can spot trends. This form is used to define the buckets and their
attributes. Refer to the following table and graph.
TABLE 5-32 Provision Port Form for Port Management - Port Thresholds Tab
Field/Button Description
Name One of the RMON statistics
Interval Interval in number of seconds, from 2 to 3600 (one hour)
Rising Threshold The number at which an alarm/log is raised when the number is exceeded.
Falling Threshold The number at which an alarm/log is raised when the number falls above this number.
Note that only when this threshold is crossed can another Rising Threshold alarm be
raised when the number crosses the Rising Threshold.
Type The type of threshold to be defined:
- ABSOLUTE - The statistic must be reset before the threshold can be crossed again
and a log produced.
- CHANGE - The logs for thresholds are produced multiple times as the thresholds
are crossed. (See Falling Threshold above to understand how this works.)
Add Threshold Bring up the Add RMON Threshold to Port Form. The fields match what will be
displayed.
Modify Threshold Modify the values for an already created threshold.
Command History Views the CLI commands and responses for the operations performed in the Port
Management application. This is the same for all tabs.

for all tabs.
