link debounce time
Use the link debounce time command to configure the debounce timer for
one or multiple interfaces. Use the no form of the command to set the link
debounce time to the default (disabled).
Syntax
link debounce time [ timeout ]
no link debounce time
• timeout—An integer value in the range of 100–5000 milliseconds. The
timeout value must be a multiple of 100.
Default Configuration
Physical interfaces do not have debounce enabled by default.
Command Mode
Interface (Physical) Configuration mode, Interface Range mode.
User Guidelines
The link bounce time configures a link bounce hysteresis on link loss of link.
Loss of link signal starts a link bounce timer. If the link is restored prior to
expiry of the timer, operation continues and the system is not notified that
that link connectivity has been lost. Hysteresis can be used to mitigate link
flaps caused by bad cabling or partially inserted optics or cables.
The debounce timer resolution is approximately 10 ms. Setting a value will
start the timer when loss of link is detected.
Ports operating at lower speeds may benefit from debounce values larger than
the default. Ports operating over fiber generally do not require larger
debounce times.
