Memory-Threshold Usage - HP FlexFabric 12900 series Command Reference Manual

Parameters
minor minor-value: Specifies the minor alarm threshold. This threshold must be equal to or less than the
memory size of the specified card. Setting this threshold to 0 disables the minor alarm function.
severe severe-value: Specifies the severe alarm threshold. This threshold must be equal to or less than the
minor alarm threshold. Setting this threshold to 0 disables the severe alarm function.
critical critical-value: Specifies the critical alarm threshold. This threshold must be equal to or less than the
severe alarm threshold. Setting this threshold to 0 disables the critical alarm function.
normal normal-value: Specifies the normal state threshold. This threshold must be equal to or greater than
the minor alarm threshold.
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command sets
thresholds for the active MPU. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device by its slot number
and the member ID. If you do not specify this option, the command sets thresholds for the global active
MPU. (In IRF mode.)
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 free-memory 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 conditions and rules for generating alarm notifications
and alarm-removed notifications, see Fundamentals Configuration Guide.
Examples
# Set the minor alarm, severe alarm, critical alarm, and normal state thresholds to 64 MB, 48 MB, 32 MB,
and 96 MB, respectively.
