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 delay-time [ mode { up | updown } ]
undo link-delay
Default
Each time the physical link of an interface goes up or comes down, the interface immediately reports the
change to the CPU.

Parameters
delay-time: Sets the physical state change suppression interval (in seconds) on the Ethernet interface. This
argument is in the range of 0 to 30. A value of 0 indicates that physical state changes are not
suppressed.
mode up: Suppresses the link-up events.
mode updown: Suppresses both the link-up and link-down events.
Usage guidelines
With the link-delay delay-time command configured:
• When the interface comes down, the link-down event is not reported to the CPU unless the interface
is still down when the suppression interval (delay-time) expires.
• When the interface goes up, the link-up event is immediately reported.
With the link-delay delay-time mode up command configured:
• When the interface goes up, the link-up event is not reported to the CPU unless the interface is still
up when the suppression interval (delay-time) expires.
• When the interface comes down, the link-down event is immediately reported.
With the link-delay delay-time mode updown command configured, when the interface comes down or
goes up, the link-down or link-up event is not reported to the CPU unless the interface is still down or 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 MSTP enabled.
