22Predefined user rolesnetwork-adminUsage guidelinesLACP MAD handles collisions differently than ARP MAD and ND MAD. To avoid conflicts, do notenable LACP MAD together with ARP MAD and ND MAD on an IRF fabric.LACP MAD requires an H3C device that supports extended LACPDUs to act as the intermediatedevice. You must set up a dynamic link aggregation group that spans all IRF member devicesbetween the IRF fabric and the intermediate device. To enable dynamic link aggregation, configurethe link-aggregation mode dynamic command on the aggregate interface.If one IRF fabric uses another IRF fabric as the intermediate device for LACP MAD, you must assignthe two IRF fabrics 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 donot want to change the current domain ID, press enter at the prompt.An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the followingcommands: irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domainIDs configured by using these commands overwrite each other.Examples# Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface. system-view[Sysname] interface bridge-aggregation 1[Sysname-Bridge-Aggregation1] link-aggregation mode dynamic[Sysname-Bridge-Aggregation1] mad enableYou need to assign a domain ID (range: 0-4294967295)[Current domain is: 0]: 1The assigned domain ID is: 1MAD LACP only enable on dynamic aggregation interface.# Enable LACP MAD on Route-Aggregation 1, a Layer 3 dynamic aggregate interface. system-view[Sysname] interface route-aggregation 1[Sysname-Route-Aggregation1] link-aggregation mode dynamic[Sysname-Route-Aggregation1] mad enableYou need to assign a domain ID (range: 0-4294967295)[Current domain is: 0]: 1The assigned domain ID is: 1MAD LACP only enable on dynamic aggregation interface.Related commandsirf domainmad exclude interfaceUse mad exclude interface to exclude an interface from being shut down when the IRF fabrictransits to the Recovery state upon detection of a multi-active collision.Use undo mad exclude interface to configure the IRF fabric to shut down an interface whenit transits to the Recovery state upon detection of a multi-active collision.Syntaxmad exclude interface interface-type interface-number
