them on, and the IRF is established.
Configure LACP MAD

# Set the domain ID of the IRF fabric to 1.
<Sysname> system-view
[Sysname] irf domain 1
# Create a dynamic aggregate interface and enable LACP MAD.
<Sysname> system-view
[Sysname] interface bridge-aggregation 2
[Sysname-Bridge-Aggregation2] link-aggregation mode dynamic
[Sysname-Bridge-Aggregation2] mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 1]:
The assigned domain ID is: 1
Info: MAD LACP only enable on dynamic aggregation interface

Configure Device C as the intermediate device
5.
Acting as the intermediate device, Device C forwards and processes extended LACPDUs sent between
Device A and Device B for MAD detection.
CAUTION:
If the intermediate device is in an IRF fabric, you must assign this fabric a different domain ID than the
LACP MAD-enabled fabric.
