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 ARP MAD or LACP MAD, you must
assign the two IRF fabrics different domain IDs for correct split detection. False detection causes IRF split.
Examples
# Set the IRF domain ID to 30.
<Sysname> system-view
[Sysname] irf domain 30
