Usage guidelines
LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate
device.
You must set up a dynamic link aggregation group that spans all IRF member devices between the IRF
fabric and the intermediate device. To enable dynamic link aggregation, configure the
link-aggregation
mode dynamic
command on the aggregate interface.
If the intermediate device is also in an IRF fabric, make sure the two IRF fabrics have different domain IDs
to avoid false detection of IRF splits.
You must enter the domain ID when you use the
mad enable
command.
Examples
# Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]: 1
The assigned domain ID is: 1
Info: MAD LACP only enable on dynamic aggregation interface.

mad exclude interface
Use
mad exclude interface
to exclude a physical network port from being shut down when the IRF fabric
transitions to the Recovery state upon detection of a multi-active collision.
Use
undo mad exclude interface
to restore the default MAD action on a physical network port.
