Use
link-delay
to set the physical state change suppression interval on an Ethernet interface.
Use

to restore the default.

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, MSTP, or Smart Link enabled.
