Chapter 64 Safeguard Engine Command
config safeguard_engine {state [enable | disable]| utilization {rising <20-100> | falling <20-100>} |
trap_log [enable | disable] | mode [strict | fuzzy]}
show safeguard_engine
64-1 config safeguard_engine
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) Specifies to configure CPU protection state to enable or disable.
enable - Specifies that CPU protection will be enabled.
disable - Specifies that CPU protection will be enabled.
utilization - (Optional) Specifies to configure the CPU protection threshold.
rising - Specifies 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 - Specifies 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) Specifies to enable or disable the trap and log mechanism.
enable - Specifies that the trap and log mechanism will be enabled.
disable - Specifies 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.
