2.1.3 Minor
Minor is the lowest level of alarm. An alarm with a severity level of minor means that system service is not affected. How-
ever, this alarm condition could lead to a major or critical alarm condition; therefore, the user should investigate the alarm.
When a minor alarm conditions is raised, the MINOR LED on the CFC faceplate will be illuminated. An LED on a card face-
plate may also be illuminated.
A log indicating a minor alarm will be prefaced by “*” as the first character in the first line of text. An example of a minor
alarm log is illustrated below.

System: Raised Port Outage Threshold
Some alarm conditions begin as a minor alarm, but as the alarm condition continues, its level will be raised. For
example, a port outage threshold alarm may initially be raised as a minor alarm. However, if more ports
encounter the same alarm condition and the number of ports in alarm increases, after a certain threshold is
reached, the alarm will become a major alarm. Furthermore, if the alarm condition continues and even more
ports encounter the same alarm condition and the number of ports in alarm increases, after a third threshold is
reached, the alarm will become a critical alarm. Thresholds for this example, a port outage, are:
• Minor - Less than 24 downstream ports are impacted by card failures and there is at least one uplink
available.
• Major - More than 24 but less than 128 downstream links are impacted by card faults and there is at
least one uplink available.
• CRITICAL - More than 128 downstream ports are impacted by card faults and/or there is no uplink
available.
2.2 Port Outage Threshold Configuration
Port outage thresholds can be configured to be either MAJOR, MINOR, or CRITIAL.
An example follows:

--------------------------------------
MINOR 1
MAJOR 24
CRITICAL 128
SET ALARMS THRESHOLD MINOR=7 MAJOR=32 CRITICAL=96
Warning(033613): 6 ports can go out of service before
an alarm is raised if the MINOR threshold is 7.
