link-delay
Use link-delay to set the physical state change suppression interval on an Ethernet interface.
Use undo link-delay to restore the default.
Syntax
link-delay [ msec ] delay-time [ mode { up | updown } ]
undo link-delay
Default
Each time the physical link of a port goes up or comes down, the interface immediately reports the change to the CPU.

Parameters
msec: Enables the physical state change suppression interval to be accurate to milliseconds. If you do not specify this keyword, the suppression interval is accurate to seconds.
delay-time: Sets the physical state change suppression interval on the Ethernet interface. A value of 0 indicates that physical state changes are immediately reported to the CPU and are not suppressed.
If you do not specify the msec keyword, the value range for this argument is 0 to 30 seconds.
If you specify the msec keyword, the value range for this argument is 0 to 10000 milliseconds, and the value must be a multiple of 100.
mode up: Suppresses the link-up events.
mode updown: Suppresses both the link-up and link-down events.
Usage guidelines
When the link-delay delay-time command is configured:
The link-down event is not reported to the CPU unless the interface is still down when the suppression interval (delay-time) expires.
The link-up event is immediately reported.
When the link-delay delay-time mode up command is configured:
The link-up event is not reported to the CPU unless the interface is still up when the suppression interval (delay-time) expires.
The link-down event is immediately reported.
When the link-delay delay-time mode updown command is configured:
The link-down event is not reported to the CPU unless the interface is still down when the suppression interval (delay-time) expires.
The link-up event is not reported to the CPU unless the interface is still up when the suppression interval (delay-time) expires.
On a port, if you configure the link-delay command multiple times, the most recent configuration takes effect.
Do not configure this command on a port with RRPP, spanning tree protocols, or Smart Link enabled.

# Set the link-down event suppression interval to 8 seconds on Ten-GigabitEthernet 1/0/1.

# Set the link-up event suppression interval to 800 milliseconds on Ten-GigabitEthernet 1/0/1.
