Equipment B start both sides start carry out LACP interaction, for the first time all can first Initial message of active transmission, tell other side oneself
Correlated condition, inside the message, two T1 fields all have been written to local time stamp.After both sides receive message, the report that will receive
The literary time is written to inside T2, can be by the position the syn position of local terminal if LACP normal process decision can enter next state
And it is sent to other side, the opposite end information package that can receive last time before sending also needs the message before to receive into message
The T1 arrived, T2 are also copied in message, and by T3 set when sending.After the syn message is received by opposite end, the time of T4
Also it is recorded.Finally, the system identifier of equipment A is less than the system identifier of equipment B, then equipment A ' can take in final polymerization message
T5, T5 are the time stamps relative to equipment A current time, and after equipment B is received, according to T1-T4 before, T5 is converted to equipment B
Time stamp, actuating station cause for gossip border polymerize when last port is to the time.
