xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide Chapter 86 Safeguard Engine Commands config safeguard_engine {state [enable | disable] | utilization {rising | falling } (1)| trap_log [enable | disable] | mode [strict | fuzzy]} (1) show safeguard_engine 86-1 config safeguard_engine Description This command is used to configure the safeguard engine for the system. Format config safeguard_engine {state [enable | disable] | utilization {rising | falling } (1)| trap_log [enable | disable] | mode [strict | fuzzy]} (1) Parameters state - (Optional) Configure the safeguard engine state to enable or disable. enable - Configure the safeguard engine state to enable. disable - Configure the safeguard engine state to disable. utilization - (Optional) Configure the safeguard engine threshold. rising - (Optional) Configure the utilization rising threshold. The range is between 20%-100%. If the CPU utilization is over the rising threshold, the switch enters exhausted mode. - Configure the utilization rising threshold. The range is between 20%100%. falling - (Optional) Configure the utilization falling threshold. The range is between 20%100%. If the CPU utilization is lower than the falling threshold, the switch enters normal mode. - Configure the utilization falling threshold. The range is between 20%100%. If the CPU utilization is lower than the falling threshold, the switch enters normal mode. trap_log - (Optional) Configure the state of the safeguard engine related to the trap/log mechanism to enable or disable. enable - If set to enable, trap and log will be active while the safeguard engine current mode is changed. disable - If set to disable, the current mode change will not trigger trap and log events. mode - (Optional) Determines the controlling method of broadcast traffic. There are two modes, strict and fuzzy. strict - In strict, the switch will stop receiving all 'ARP not to me' packets (the protocol address of the target in the ARP packet is the Switch itself). That means no matter what reasons cause the high CPU utilization (may not be caused by ARP storm), the Switch reluctantly processes any 'ARP not to me' packets in exhausted mode. fuzzy - In fuzzy mode, the switch will adjust the bandwidth dynamically depending on some reasonable algorithm. Restrictions Only Administrator, Operator and Power-User level users can issue this command. 925
