Parameters
domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and prevent
IRF fabrics from interfering with one another.
If you use a member device in one IRF fabric as the intermediate device for performing LACP MAD, ARP
MAD, or ND MAD for another IRF fabric, you must assign the two IRF fabrics different domain IDs to
avoid false detection of IRF split.
Examples
# Set the IRF domain ID to 10.

[Sysname] irf domain 10

irf link-delay

Use irf link-delay to set a delay for the IRF ports to report a link down event.
Use undo irf link-delay to restore the default.
Syntax
irf link-delay interval
undo irf link-delay
Default
The IRF link down event report delay is 4 seconds.

Parameters
interval: Sets the IRF link down report delay, in the range of 0 to 30000 milliseconds.
Usage guidelines
An IRF link down report delay helps avoid link flapping causing frequent IRF splits and merges 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.
