Article summary

The unit provides alarm functions to monitor and report on the status of the unit of the traffic performance and of other components.

Setting General Alarms

To set up general alarms

  1. Access the page System ▶Alarm ▶General.

  2. Complete the required fields, then click Apply.

For more information on specific parameters, refer to the following table.

Alarm Settings (System ▶Alarm ▶General)

Notification

ParameterDescription
Enable LED ReportingEnables the reporting of alarms by activating the appropriate LED on the unit that corresponds to the severity, e.g. minor, major or critical. This option also enables alarm reporting in the GUI banner. The physical LEDs (unit's front panel) and the pseudo-LEDs (banner) are linked.
Enable Syslog ReportingEnables the reporting of alarms by creating entries in the syslog.
Enable SNMP ReportingEnables the reporting of alarms via SNMP traps from Accedian’s private MIB.
Enable 802.3ah ReportingEnables reporting of alarms via 802.3ah OAMPDUs using organization-specific events.

Thresholds

ParameterDescription
Threshold On (Soaking time in msecs)The delay after an event is detected before the alarm notification occurs.
Threshold Off (Soaking time in msecs)The delay after an event clears before the alarm notification clears.

Customizing Alarms

To customize an alarm

  1. Access the page System ▶Alarm ▶Configuration.
    The settings for all alarms are displayed.

  2. Click the Number of the alarm that you want to edit.
    The Alarm Configuration page appears.

  3. Complete the required fields , then click Apply.

    Note: If you modify an alarm's configuration, then decide to discard those changes, click Reset to revert to the last set of saved configuration values. Once you click Apply, however, you must manually restore the previous configuration values.

For more information on specific parameters, refer to the following table.
