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 one IRF fabric uses another IRF fabric as the intermediate device for LACP MAD, ARP MAD, or ND
MAD, you must assign the two IRF fabrics different domain IDs for correct split detection. False
detection causes IRF split.
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the following
commands:
irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domain
IDs configured by using these commands overwrite each other.
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view
[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.
