Link-Delay Mode Up; Loopback - HP 6125G Command Reference Manual

link-delay mode up

Syntax
link-delay delay-time mode up
undo link-delay
View
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.
Examples
# Enable link down suppression on GigabitEthernet 1/0/1, setting the suppression interval to 10
seconds.

[Sysname] interface gigabitethernet 1/0/1
