Parameters
minor minor-value: Specifies the minor alarm threshold in the range of 0 to 1237. This threshold
must be equal to or less than the normal state threshold. Setting this threshold to 0 disables the
minor alarm feature.
severe severe-value: Specifies the severe alarm threshold in the range of 0 to 1237. This threshold
must be equal to or less than the minor alarm threshold. Setting this threshold to 0 disables the
severe alarm feature.
critical critical-value: Specifies the critical alarm threshold in the range of 0 to 1237. This threshold
must be equal to or less than the severe alarm threshold. Setting this threshold to 0 disables the
critical alarm feature.
normal normal-value: Specifies the normal state threshold in the range of 0 to 1237. This threshold
must be equal to or less than the total memory size.
slot slot-number: Specifies an IRF member device by its member ID or a PEX by its virtual slot
number. If you do not specify this option, the command sets free-memory thresholds for the master
device.
cpu cpu-number: Specifies a CPU by its number. The cpu-number argument must be 0.
Usage guidelines
To ensure correct operation and improve memory utilization, the system monitors the amount of free
memory space in real time. When a threshold is exceeded, the system sends an alarm notification or
an alarm-removed notification to affected feature modules or processes so they can take
countermeasures. For more information about the thresholds, see Fundamentals Configuration
Guide.
