Parameters
domain-id
: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
CAUTION:
Changing the IRF domain ID of an IRF member device will remove that member device from the IRF
fabric. This member device will be unable to exchange IRF protocol packets with the remaining
member devices in the IRF fabric.
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
