link-delay
Syntax
link-delay delay-time
undo link-delay
View
Ethernet port view
Parameters
delay-time : Port state change delay to be set. This argument is in the range 2 to 10 (in seconds).
Description
Use the link-delay command to set the port state change delay.
Use the undo link-delay command to restore the default.
By default, the port state change delay is 0 seconds, that is, the port state changes without any 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 set a port state change delay.
