Chapter 7 Configure Switch Features
Port Alarms
From the Configure menu, choose Alarm Settings and click the Port tab.
For each port, choose an Alarm Profile and set the FCS threshold. The frame
check sequence (FCS) error hysteresis threshold is expressed as a percentage of
fluctuation from the FCS bit error rate. The default setting is 8 percent. You
can adjust the percentage to prevent toggling the alarm condition when the
FCS bit error rate fluctuates near the configured bit error rate. Valid
percentages for port settings are 6…11.
Alarm Profiles
You can use alarm profiles to apply a group of alarm settings to multiple
interfaces. These alarm profiles are created for you:
• defaultPort
• ab-alarm (created during Express Setup)
From the Configure menu, choose Alarm Profiles.
