Description
This command is used to configure the CPU protection control for the system.
Format
config safeguard_engine {state [enable | disable]| utilization {rising <20-100> | falling <20-
100>} | trap_log [enable | disable] | mode [strict | fuzzy]}
Parameters
state
- (Optional) Specify to configure CPU protection state to enable or disable.
enable
- Specify that CPU protection will be enabled.
disable
- Specify that CPU protection will be enabled.
utilization
- (Optional) Specify to configure the CPU protection threshold.
rising
- Specify utilization rising threshold. The range is between 20%-100%. If the CPU
utilization is over the rising threshold, the Switch enters exhausted mode.
<20-100>
- Enter the utilization rising value here. This value must be between 20 and 100.
falling
- Specify utilization falling threshold. The range is between 20%-100%. If the CPU
utilization is lower than the falling threshold, the Switch enters normal mode.
<20-100>
- Enter the utilization falling value here. This value must be between 20 and 100.
trap_log
- (Optional) Specify to enable or disable the trap and log mechanism.
enable
- Specify that the trap and log mechanism will be enabled.
disable
- Specify that the trap and log mechanism will be disabled.
mode
- (Optional) Determines the control method of broadcasting traffic.
strict
- In strict mode, the Switch will stop receiving all ‘IP broadcast’ packets, packets from
the untrusted IP address, and reduce the bandwidth of ‘ARP-not-to-me’ packets (the
protocol address of the target in the ARP packet is the Switch itself) to the Switch. That
means that no matter what the reasons for high CPU utilization are (may not be caused by
an ARP storm), the Switch reluctantly processes the specified traffic, mentioned previously
in the Exhausted mode.
fuzzy
- In fuzzy mode, the Switch will adjust the bandwidth dynamically.
Restrictions
Only Administrators, Operators and Power-Users can issue this command.
