Setting the Port State Change Delay

During a short period after you connect your switch to another device, the connecting port may go up
and down frequently due to hardware compatibility, resulting in service interruption.
To avoid situations like this, you may introduce a port state change delay.
The port state change delay takes effect when the port goes down but not when the port goes up.
Follow these steps to set the port state change delay:
To do ...
Enter system view
Enter Ethernet interface
view
Use the command ...
system-view
interface interface-type
interface-number
1-10
