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.
Syntax
mad exclude interface interface-type interface-number
undo mad exclude interface interface-type interface-number
Default
All physical network ports but the IRF physical ports and console port shut down when the IRF fabric
transitions to the Recovery state.

Parameters
interface-type interface-number: Specifies a port by its type and number.
Usage guidelines
MAD action is not configurable for IRF physical ports.
When MAD detects that an IRF fabric has split into two or more identical active IRF fabrics, only the IRF
fabric whose master has the lowest member ID among all the masters can still forward data traffic. MAD
changes its status to Recovery on all the other IRF fabrics and shuts down all their physical ports except
the physical IRF ports and those manually configured to not shut down.
If a port must be kept in up state for special purposes such as Telnet connection, exclude it from the
shutdown action. To avoid problems, HP recommends not excluding any ports except the ports used for
Telnet and MAD.
The ports that have shut down by MAD come up when the member devices reboot to join the recovered
IRF fabric. If auto recovery fails because the current master fails or any other exception occurs, use the
mad restore command to manually recover the member devices and bring up the ports.
Examples
# Exclude Ten-GigabitEthernet 2/5/0/1 from being shut down when the MAD status transitions to
Recovery.
