Memory-Threshold Usage - HP FlexFabric 7900 Series Command Reference Manual

severe severe-value: Specifies the severe alarm threshold in MB. 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 MB. 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 MB. 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 or switching fabric module. (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 or switching fabric module. (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.

memory-threshold usage
Use memory-threshold usage to set the memory usage threshold.
Use undo memory-threshold usage to restore the default.
Syntax
In standalone mode:
memory-threshold [ slot slot-number [ cpu cpu-number ] ] usage memory-threshold
undo memory-threshold [ slot slot-number [ cpu cpu-number ] ] usage
In IRF mode:
memory-threshold [ chassis chassis-number slot slot-number [ cpu cpu-number ] ] usage
memory-threshold
undo memory-threshold [ chassis chassis-number slot slot-number [ cpu cpu-number ] ] usage
Default
The memory usage threshold is 100%.
