Parameters
Parameters
Description
state
Configure the safeguard engine state to
enable
or
disable
.
trap_log
Configure the state of safeguard engine related trap/log
mechanism to
enable
or
disable
. If set to
enable
, trap and log will
be active while the safeguard engine current mode is changed. If
set to
disable
, current mode change will not trigger trap and log
events.
mode
Determines the controlling method of broadcast traffic.
Here are two modes (
strict
and
fuzzy
). In
strict
, the Switch will
stop receiving all ‘ARP not to me’ packets (the protocol
address of target in ARP packet is the Switch itself). That
means no matter what reasons cause the high CPU utilization
(may not caused by ARP storm), the Switch reluctantly
processes any ’ARP not to me’ packets in exhausted mode. In
fuzzy
mode, the Switch will adjust the bandwidth dynamically
depend on some reasonable algorithm .
utilization
Configure the safeguard engine threshold.
