Configuring Interfaces
To configure the debounce timer on a port, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# link debounce
[time debounce_time ]
Router(config-if)# no link debounce
Step 3
Router# show interfaces debounce

On all 10-Gigabit Ethernet ports, the Debounce Timer Disabled is 10 milliseconds and the Debounce
Note
Timer Enabled is 1 second.
This example shows how to enable the port debounce timer on Fast Ethernet port 5/12:
Router(config)# interface fastethernet 5/12
Router(config-if)# link debounce
Router(config-if)# end
This example shows how to display the port debounce timer settings:

The time keyword is supported only on fiber Gigabit Ethernet ports.
You can increase the port debounce timer value in increments of 100 milliseconds up to
5000 milliseconds on ports operating at 1000 Mpbs over copper media.
Only releases earlier than Release 12.2(17a)SX support WS-X6502-10GE.
Releases earlier than Release 12.2(18)SXD assume that 10 Gbps ports use fiber media.
Release 12.2(18)SXD and later releases recognize 10 Gbps copper media.
Releases earlier than Release 12.2(18)SXD do not detect media-only changes.
Release 12.2(18)SXD and later releases detect media-only changes.
