2. You can choose one of the following:
• Click Activate to enable synchronization and close the Configure Date and Time dialog
box. The switch date and time synchronize with the HAFM appliance date and time at the
next update period (at least once daily) and Daylight Savings Time automatically updates.
• Click Sync Now to synchronize the switch and HAFM appliance immediately. The Date
and Time Synced dialog box appears.
• Click OK.
• In the Configure Date and Time dialog box, click Activate to enable synchronization and
close the Configure Date and Time dialog box.
Configuring threshold alerts
A threshold alert notifies users when the transmit (Tx) or receive (Rx) throughput reaches specified
values for specific switch ports or port types, (E_Ports, F_Ports, or FL_Ports).
You are notified of a threshold alert by:
• An attention indicator (yellow triangle) that displays on the port in the Hardware View.
• An attention indicator (yellow triangle) that displays in the Alert column of the Port List View.
• An attention indicator (yellow triangle) that displays by the Threshold Alerts box in the Port
Properties dialog box.
• Detailed threshold alert data recorded in the Threshold Alert Log.
Threshold alert configuration parameters
Use the Threshold Alerts option on the Configure menu to configure the following:
• Name for the alert.
• Type of threshold for the alert (Rx, Tx, or either).
• Active or inactive state of the alert.
• Threshold criteria:
• Percent traffic capacity utilized. This is the percent of the port’s throughput capacity
achieved by the measured throughput. This setting constitutes the threshold value. For
example, the value of 50 means that the port’s threshold is reached when throughput is 50%
of capacity.
• Time interval during which throughput is measured and alert notification can occur.
• The maximum cumulative time that the throughput percentage can be exceeded during the
set time interval before an alert is generated.
• Ports for which you are configuring threshold alerts.
You can configure up to 16 alerts, and any number of alerts can be active at one time.
Use the following procedures to create a new threshold alert, or to modify, activate, deactivate, or
delete an alert.
