Views

Predefined user roles

Parameters
interval
: Specifies the link flapping detection interval in seconds. The value range for this
argument is 10 to 60. The default value for this argument is 10.
threshold
: Specifies the link flapping detection threshold in the range of 5 to 10. The default value
for this
argument is 5.
Usage guidelines
Link flapping protection takes effect only when it is enabled in both system view and interface view.
If you do not specify the
interval
interval
or
threshold
threshold
option when you
execute the
port link-flap protect enable
command, the command uses the default
settings.
If you specify the
interval
or
threshold
keyword when you execute the
undo port
link-flap protect enable
command, the command restores the default setting for the
keyword.
With link flapping protection enabled on an interface, when the interface goes down, the system
enables link flapping detection on the interface. During the link flapping detection interval, if the
number of detected flaps reaches or exceeds the link flapping detection threshold, the system shuts
down the interface.
To bring up an interface that has been shut down by link flapping protection, execute the
undo
shutdown
command.
This command, the
dampening
command, and the
link-delay
command are mutually exclusive
on an Ethernet interface.
Examples
# Enable link flapping protection on an interface. Set the link flapping detection interval to 10 seconds,
and set the link flapping detection threshold to 5.
