during a short time.
An IRF port handles link down and link up events, as follows:
When the IRF link changes from up to down, the port does not immediately report the change
•
to the IRF fabric. If the IRF link state is still down when the delay time is reached, the port
reports the change to the IRF fabric.
When the IRF link changes from down to up, the link layer immediately reports the event to
•
the IRF fabric.
Examples
# Set the IRF link down report delay to 300 milliseconds.
<Sysname> system-view
[Sysname] irf link-delay 300
irf link-status detect enable
Use irf link-status detect enable to enable IRF link failure detection.

undo irf link-status detect enable
Default
The IRF link failure detection is enabled.

Usage guidelines
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the undo irf link-status detect enable command configuration, even if you have
saved the configuration.
After the IRF link failure detection is enabled, the system automatically examines the status of each
IRF physical link to discover IRF link failure events.
Examples
# Disable the IRF link failure detection.
<Sysname> system-view
[Sysname] undo irf link-status detect enable
irf link-status auto-recovery enable
Use irf link-status auto-recovery enable to enable the IRF link failure auto recovery.
