Chapter2 Catalyst 6500 Series Switch and ROM Monitor Commands set port debounce
set port debounce
To enable or disable the debounce timer or configure the timer setting on a per-port basis, use the set
port debounce command.
set port debounce mod/port {enable | disable}
set port debounce mod/port delay time
Syntax Description
Defaults By default, the debounce timer is disabled on all ports.
When the debounce timer is disabled, the default debounce timer values are as follows:
•10/100 ports—300 milliseconds
•100BASE-FX ports—300 milliseconds
•10/100/1000BASE-T and gigabit TX ports—300 milliseconds
•10-gigabit ports—10 milliseconds
When the debounce timer is enabled, the default debounce timer values are as follows:
•10/100 ports—3100 milliseconds
•100BASE-FX ports—3100 milliseconds
•10/100/1000BASE-T and gigabit TX ports—3100 milliseconds
•10-gigabit ports—100 milliseconds
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines The debounce timer is the time the firmware waits before notifying the supervisor engine of a link
change at the physical layer.
Setting the debounce timer value to 200 milliseconds or from 300 to 5000 milliseconds is possible only
for gigabit fiber ports. You do not need to enable the debounce timer on a gigabit fiber port before
adjusting the timer. Any timer value that is greater than the default value in disabled state is considered
a value that enables the timer.
mod/port Number of the module and the port on the mod ule.
enable | disable Enables or disables the debounce timer.
delay Sets the debounce timer for gigabit fiber ports.
time Amount of time the firmware waits before notifying the
supervisor engine of a link change; valid values are 200
milliseconds or from 300 to 5000 milliseconds. This is supported
on gigabit fiber ports only. See the “Usage Guidelines” section
for more information.
