Usage guidelines
This command is supported only in IRF mode. When you change the operating mode from IRF to standalone, the IRF domain setting is lost, regardless of whether you have saved the configuration.
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.
In an MDC environment, the irf domain command is available only on the default MDC. The mad enable, mad arp enable, and mad nd enable commands are available on all MDCs. If you change the IRF domain ID in one MDC, the IRF domain IDs in all other MDCs change automatically.
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view [Sysname] irf domain 10
