Parameters
delay-time: Sets the physical state change suppression interval (in seconds) on the Ethernet interface. The
value range for this argument is 0 to 30. A value of 0 indicates that physical state changes are
immediately reported to the CPU and are not suppressed.
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 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.
Examples
# Set the link-down event suppression interval to 8 seconds on interface Ten-GigabitEthernet 1/0/1.
