Configuring the Switch
Configure 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 field in the Port Properties dialog box.
• Detailed threshold alert data recorded in the Threshold Alert Log.
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.
