PLUGGABLES AND CABLING COMMANDS
FIBER
-MONITORING BASELINE
CAUTION: We do not recommend setting a fixed value because gradual change over
time caused by temperature fluctuations, etc. could lead to unnecessary alarms.
If you use the averaging method, you can optionally specify how often Active Fiber
Monitoring polls the cable to determine the baseline. This allows Active Fiber
Monitoring to update the baseline less often than it polls the device for
monitoring.
In order to prevent the theoretical possibility of slow clamping, you can set the
baseline interval to a large value, so that the baseline average is only updated with
the current reading (for example) once per day or once per hour.
As fiber attenuation can be affected by ambient temperature, take care if changing
the baseline interval in environments with large daily temperature fluctuations.
Example To set the baseline optical power to a moving average of the last 30 monitoring
readings on port1.0.1 and port1.0.4, use the command:
awplus(config)# interface port1.0.1-port1.0.4
awplus(config-if)# fiber-monitoring baseline average 30
To calculate the baseline based on 12 values taken 24 hours (86400 seconds) apart,
instead of using the monitoring interval, use the command:
awplus(config)# interface port1.0.1-port1.0.4
awplus(config-if)# fiber-monitoring baseline average 12
interval 86400
To set the baseline to its default, averaging the last 12 readings, use the command:
awplus(config)# interface port1.0.1-port1.0.4
awplus(config-if)# no fiber-monitoring baseline
