S1. the double hair functions of opening upper united dish increase the configuration for opening the double hair functions in first line of a couplet port that is, in PON system,
The configuration is saved using database, and active and standby synchronization and configuration is supported to restore.
By transmitting order to lower levels in the active system control unit of S2.PON system, double hair functions of specified first line of a couplet port are opened
Afterwards, upper united dish is parsed after receiving the configuration message of the double hair functions in enabled first line of a couplet port that main control unit issues, passes through CPID
Its value is issued to register by (computer program integrated document, Computer Programme Integral Document),
Making the physical state of the first line of a couplet port in back-up system control unit becomes UP from DOWN.If upper in back-up system control unit
The physical state for joining port is not UP state, then using the upper united dish for supporting double hair functions.
S3. after the physical state of the first line of a couplet port in back-up system control unit is UP state, further judge spare system
Can system control unit receive the LACP protocol massages of opposite equip. transmission.If back-up system control unit cannot receive pair

The system identifier in LACP protocol massages that system control unit and back-up system control unit are sent after reunification, from active system control
Unit processed will be identical with the CPU of the back-up system control unit LACP protocol massages sent.Since back-up system controls list
First exchange chip can not send the CPU LACP message issued, and active system control unit replaces back-up system control single
Member completes the interaction of LACP protocol massages with opposite equip..
If S5. LACP agreement has used virtual mac address, the LACP agreement of back-up system control unit is further judged
Whether polymerization success if the LACP agreement of back-up system control unit does not polymerize success checks network environment and LACP
Configuration.
It is main since LACP agreement uses virtual mac address after the LACP protocol aggregation success of active system control unit
The protocol massages that the LACP message issued with system control unit and back-up system control unit issue are identical, back-up system control
Unit receives and sends LACP message to opposite equip. between passing through active system control unit.Due to the first line of a couplet port open of PON system
Double hair functions, active system control unit and back-up system control unit can receive the LACP association that opposite equip. sends over
Message is discussed, in this way, the LACP agreement in active system control unit and back-up system control unit sends and receivees LACP message
Normally, can negotiate successfully with opposite equip..LACP state machine in active system control unit and back-up system control unit
Normal operation, member port can polymerize in groups, and issue hardware table item to exchange chip.Active system control unit and spare
LACP protocol state machine state on system control unit is identical, and the hardware table item for being issued to exchange chip is identical, different
, the list item in back-up system control unit is not involved in business datum forwarding.
If the S6. LACP protocol aggregation success of back-up system control unit, carries out masterslave switchover, and observe aggregated links
Whether disconnect, customer service it is whether abnormal.
Since the time of masterslave switchover is very short, usually within 50ms, before masterslave switchover in back-up system control unit
The member port of LACP polymerize in groups, and issue driving list item, after masterslave switchover, back-up system control unit rises immediately
For primary system control unit, due to before switching in back-up system control unit LACP protocol status, hardware table item with master
It is identical with system control unit, it does not need to re-start negotiation at this time, it is thus only necessary to LACP protocol massages periodically occur
Safeguard the connectivity of aggregated links.It, can be from the synchronous LACP of current active system control unit when active system control unit is restarted
Virtual mac address control switch and address, double be transported to of LACP configuration data, upper united dish are set, and become back-up system control after starting
Unit processed can equally receive the LACP protocol massages of opposite equip. transmission.LACP protocol state machine normal operation, and under
Hair polymerize list item information to exchange chip.
In conclusion opposite equip. will not perceive the interruption of masterslave switchover short time, LACP polymerization before and after masterslave switchover
Link not will disconnect, and the business such as voice, data and video of the user carried in corresponding aggregated links are unaffected, and protect
It is unaffected masterslave switchover customer service has been hindered.
