Parameters
delay-time
: Sets a link down suppression interval, ranging from 2 to 10 seconds.
Description
Use the
link-delay
command to enable an Ethernet port to suppress link down events. When the physical
link of the port goes down, the port suppresses the link down event and starts a timer. When the timer
expires, the physical layer reports the event to the upper layers.
Use the
undo link-delay
command to restore the default.
By default, link down suppression is disabled. Ethernet ports report link down events to the upper layers
without delay.
NOTE:
•
The
link-delay mode up
command
and the
link-delay
command are mutually exclusive with each other
on the current port. When both commands are configured on the port, the one that is configured earlier
is disabled.
•
Link down suppression setting does not take effect on administratively down events. When you shut
down the port with the
shutdown
command, the port reports the event without delay.
•
H3C does not recommend that you use this command on ports that are disabled with RRPP, MSTP, or
Smart Link.

Parameters
delay-time
: Sets a link up suppression interval, ranging from 2 to 10 seconds.
Description
Use the
link-delay
delay-time
mode up
command to enable an Ethernet port to suppress link up events.
When the physical link of the port comes up, the port suppresses the link up event and starts a timer.
When the timer expires, the physical layer reports the event to the upper layers.
Use the
undo link-delay
command to restore the default.
