Setting the Port Configuration
To set the debounce timer on a port, perform this task in privileged mode:
This example shows how to enable the debounce timer on port 2/1:
Console> (enable)
set port debounce 2/1 enable
Debounce is enabled on port 2/1
Warning: Enabling port debounce causes Link Up/Down detections to be delayed.
It results in loss of data traffic during debouncing period, which might
affect the convergence/reconvergence of various Layer 2 and Layer 3 protocols.
Use with caution.
Console> (enable)
This example shows how to display the per-port debounce timer settings:
Console> (enable)
show port debounce

2/1 enable
2/2 disable
Console> (enable)
Modifying the Port Debounce Timer Setting
Note
Modifying the port debounce timer setting is possible only on fiber Gigabit Ethernet ports.
You can increase the port debounce timer value in increments of 100 up to 5000 milliseconds. You do
not need to enable the debounce timer on the port before adjusting the timer value. Specifying any timer
value that is greater than the default value in the disabled state enables the debounce timer.
To modify the port debounce timer setting on a port, perform this task in privileged mode:
