Arp Mad - HP FlexFabric 5700 series Configuration Manual

If the domain IDs and active IDs sent by all the member devices are the same, the IRF fabric is
•
integrated.
If the extended LACPDUs convey the same domain ID but different active IDs, a split has occurred.
•
LACP MAD handles this situation as described in
Figure 5 LACP MAD scenario

ARP MAD

ARP MAD detects multi-active collisions by using extended ARP packets that convey the IRF domain ID
and the active ID.
You can set up ARP MAD links between neighbor IRF member devices, or between each IRF member
device and an intermediate device (see
spanning tree feature between the IRF fabric and the intermediate device.
"Collision
Figure 6). If an intermediate device is used, you must also run the
9
handling."
