Figure 10-7 LACP MAD detection

LACP MAD detection is achieved through the extended LACP protocol packets

content. It defines a new TLV (Type Length Value) in the extended field of LACP protocol

packets and this TLV is used for the ActiveID of the interaction VSF. For VSF system,

ActiveID value is unique, and it is expressed by the member number of the master device

in VSF. After enabling LACP MAD detection, the member device interact the ActiveID

information with other member devices through the LACP protocol packets.

When VSF is running normally, the ActiveID values of the LACP protocol packets sent

by all member devices are the same, there is no Active conflict.

When the VSF is split into two vsf, the ActiveID values of the LACP protocol packets

sent by different VSF member devices are the different and multiple Active conflict will be

detected.
