storm-control timer (Global)
Use this command to configure the timer options. The timers are used to
implement a storm control shutdown action. Use the no form of the command to
return the default settings.

SECONDS }
no storm-control { time-interval | countdown | auto-recover-time}
Default
time-interval SECONDS : 5 seconds
countdown time SECONDSr : 0 seconds
auto-recover-time SECONDS : 0 seconds

Usage Guideline
If the action option is set to shutdown, the port will enter shutdown mode (i.e. the
port is blocked) when the threshold is exceeded. If the traffic rate has been
higher than the threshold for a configurable period (countdown timer), the port
will enter into shutdown forever mode (i.e. the port is disabled and the status is
link-down).
When a port is in "shutdown mode", before the port enters into shutdown forever
mode it can recover and the port will exit the shutdown mode. if the receiving rate
is higher than the falling threshold (80% of the threshold), and lower than the
threshold, the port will exit the shutdown mode after a period of time and the
timer will then be half of the
countdown timer.
Furthermore, if the receiving rate is lower than the falling threshold the port will
be recovered immediately.
If the auto_recover_time value is non-zero, the port will be automatically
recovered to the normal situation after the recovery time. Otherwise, the port will
Syntax Description
time-interval
SECONDS
Software will monitor the counter of received broadcast or multicast packets
periodically based on this user defined interval. The range of the checking
interval (
SECONDS ) is from 5 to 30 seconds.
countdown
SECONDS
If a port is in shutdown mode and this timer runs out, the port will be placed in
shutdown forever mode. If the value is '0' the function of shutdown forever is
disabled.
The valid range for this setting is 0, 180 - 1800 seconds.
auto-recover-time
SECONDS
Specifies the time that a port is in shutdown forever mode, from which it can be
automatically recovered. When the value is set to '0' a port cannot recover from
forever shutdown.
The valid range for this setting is 0, 300 - 1800 seconds.
