Usage guidelines

LACP MAD handles collisions in a different way than BFD MAD. To avoid conflicts, do not use LACP

MAD together with BFD MAD.

LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate

HP device that also supports LACP MAD packets.

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 an IRF fabric, make sure the two IRF fabrics have different domain IDs

for correct split detection. False detection causes IRF split.

When you use the mad enable command, the system prompts you to enter a domain ID. If you do not

want to change the current domain ID, press Enter at the prompt.

NOTE:

• An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the irf domain

or mad enable command. The IRF domain IDs configured with these commands overwrite each other.

• You can execute the mad enable command on any MDCs. If you change the IRF domain ID in one

MDC, the new IRF domain ID takes effect immediately on all MDCs.

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

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

transits 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.
