FIBER MONITORING BASELINE

fiber-monitoring baseline

Overview Use this command to configure how the baseline value for comparison is
calculated for active fiber monitoring on the port.
Note that alarm generation will not commence until the link has been up for a full
averaging period.
Use the no variant of this command to set the fiber-monitoring baseline to its
default value.
fiber-monitoring baseline average <12-150> [interval <2-86400>]
Syntax
fiber-monitoring baseline fixed <1-65535>
no fiber-monitoring baseline
Default The default is a moving average of the last 12 values, taken at the same interval as
the monitoring interval. The monitoring interval is set using the fiber-monitoring
interval command. If the monitoring interval is set to its default of 5 seconds, the
fiber-monitoring baseline default will be the average over the last minute.
Mode Interface Configuration for a fiber port
Usage notes There are two ways to configure the baseline. The first is to choose a number of
readings to average. This is the default and recommended method. The second is
to set a fixed value in units of x0.0001mW.
If a fixed value is required, the easiest way to choose a value is to enable fiber
monitoring on the port and use the show system fiber-monitoring command to
see what readings you can expect.

Parameter Description
average
Set the baseline optical power received to be based on the
<12-150>
moving average of the specified number of most recent
(non-zero) values. Default is to use this setting and 12 values.
interval
Optionally, specify the optical power polling interval for
<2-86400>
determining the baseline, in seconds. By default, the baseline
polling interval is the same as the monitoring polling interval,
which is 5 seconds by default.
If specified, this baseline interval should be larger than the
monitoring interval.
Even if you specify a baseline interval, Active Fiber Monitoring will
use the monitoring interval to calculate the initial baseline
average. This means the first x baseline readings will be taken at
the monitoring interval, where x is the number of readings
specified in the average parameter.
See Usage below for more information.
fixed
Set the baseline to a fixed level of received optical power in
<1-65535>
0.0001mW. Not recommended—see Usage below.
