Use undo mad enable to disable LACP MAD. By default, LACP MAD is disabled. LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate HP device that also supports LACP MAD packets. When you use LACP MAD, follow these guidelines: • The intermediate device must be an HP device that support extended LACP for MAD. • If the intermediate device is in an IRF fabric, assign this fabric a different domain ID than the LACP MAD-enabled fabric to avoid false detection of IRF partition. • Use dynamic link aggregation mode. MAD is LACP dependent. Even though LACP MAD can be configured on both static and dynamic aggregate interfaces, it takes effect only on dynamic aggregate interfaces. • Configure link aggregation settings also on the intermediate device.
