link-delay mode up Syntax link-delay delay-time mode up View undo link-delay Ethernet interface view Default level 2: System level Parameters delay-time: Sets the link down suppression interval, ranging from 2 to 10 seconds. Description Use link-delay delay-time mode up to enable an Ethernet interface to suppress link down events. When the physical link of the interface goes down, the interface suppresses the link down event and starts a timer. When the timer expires, the physical layer reports the event to the upper layers. Use undo link-delay to restore the default. By default, the link down suppression interval on an Ethernet interface is 0 seconds. The link-delay mode up command and the link-delay command supersede each other. The command that is configured last takes effect. Do not configure this command on ports with RRPP, MSTP, or Smart Link enabled.
