Embodiment one
When the present embodiment describes the member device in pile system in detail as non-master member device, how to carry out MAC
Address synchronization.
Seeing Fig. 2, Fig. 2 is the method flow schematic diagram synchronizing MAC Address in the embodiment of the present invention one.Concrete steps
For:
Step 201, the member device in pile system knows that when needing to synchronize MAC Address, batch reads this member and sets
The MAC Address that standby hardware learns, deletes the MAC Address of the port numbers that corresponding ports information is other member devices
MAC Address after removing is as MAC Address to be synchronized.
It is the port of other member devices that this member device deletes port information in all MAC Address that batch reads
Number MAC Address, i.e. get rid of and synchronized by MAC Address, and learn on the common port of other member devices
MAC Address.
In the specific embodiment of the invention, common port defines relative to aggregation port.Any member equipment this locality adds
The port of aggregation group is referred to as aggregation port, and the port not adding aggregation group is referred to as common port.
The port information that MAC Address is corresponding is port numbers or aggregation group mark ID, and wherein, port numbers passes through chip id
Identifying with physical port number, chip id is the port on which member device for distinguishing this port.
How member device is known needs to synchronize MAC Address, for this member device as main member device and non-master
During member device, it is achieved different.Describe main member device separately below and non-master member device knows what needs synchronized
The process of MAC Address:
When this member device is as main member device, configure the first Preset Time and the second Preset Time；Wherein,
One Preset Time is less than the MAC address aging time, and the second Preset Time is more than the MAC address aging time.
There is above-mentioned configuration visible within a MAC address aging cycle, MAC Address repeatedly can be carried out and synchronize,
The most main member device repeatedly sends stacking message, triggers each member device and synchronizes MAC Address.In pile system
Each member device carries out aging ageing time to MAC Address and is configured to identical.
Main member device arranges the second Preset Time more than the MAC address aging time, is i.e. poly-to make port information
The synchronizing cycle of the MAC Address of charge-coupled mark is more than the ageing time of MAC Address, it is to avoid corresponding ports information is poly-
The MAC Address of charge-coupled mark, because each member device in pile system is mutually synchronized MAC Address, and the oldest
Change.
When the first Preset Time then, know need synchronize MAC Address, and determine need synchronize corresponding ports information
For the MAC Address of the port numbers of this member device, and the MAC that asynchronous corresponding ports information is aggregation group mark
Address；And send the port numbers that stacking other member devices of message informing synchronization corresponding ports information is this member device
MAC Address, and the MAC Address that asynchronous corresponding ports information is aggregation group mark.
When the second Preset Time then, know need synchronize MAC Address, determine need synchronize corresponding ports information be
The MAC Address of the port numbers of this member device, and synchronize the MAC Address that corresponding ports information is aggregation group mark；
And send the MAC of the port numbers that stacking other member devices of message informing synchronization corresponding ports information is this member device
Address, and synchronize the MAC Address that corresponding ports information is aggregation group mark.
When this member device is as non-master member device, when receiving the stacking message that main member device sends, know
Need to synchronize MAC Address.
When in this stacking message, notice synchronizes the MAC Address of the port numbers that corresponding ports information is this member device, and
When asynchronous corresponding ports information is the MAC Address of aggregation group mark, determines and need to synchronize corresponding ports information for this
The MAC Address of the port numbers of member device, and the MAC Address that asynchronous corresponding ports information is aggregation group mark.
When this stacking message notifying, other member devices synchronize the port numbers that corresponding ports information is this member device
MAC Address, and when synchronization corresponding ports information is the MAC Address that aggregation group identifies, determines and need to synchronize corresponding end
Message breath is the MAC Address of the port numbers of this member device, and synchronization corresponding ports information is aggregation group mark
MAC Address.
As can be seen here, when main member device synchronizes MAC Address, main member device first arranged is preset
Time and the second Preset Time are to triggering constantly.Main member device triggers when synchronizing MAC Address, sends stacking simultaneously
Message trigger non-master member device synchronizes MAC Address.
Step 202, this member device is if it is determined that need to synchronize the port numbers that corresponding ports information is this member device
MAC Address, and the MAC Address that asynchronous corresponding ports information is aggregation group mark, then from described to be synchronized
In MAC Address, filter out and be active and the MAC ground of port numbers that corresponding ports information is this member device
Location, and according to port information corresponding to the MAC Address filtered out and the MAC Address filtered out and VLAN
ID, builds broadcasting packet and other member devices in pile system send.
On determining the only synchronous study MAC Address to the common port in this locality, asynchronous study to aggregation group identifies
MAC Address time, only by MAC Address learning that is all to be synchronized and that be active to local common end
On mouth rather than aggregation group mark on MAC Address be synchronized to other member devices.
The MAC Address that each is filtered out by this member device, and should as the source MAC of broadcasting packet
Port information that the MAC Address that filtered out is corresponding and VLAN ID, carry hardware in the broadcasting packet built
Practise on the position that MAC Address can learn.
Step 203, this member device is if it is determined that need to synchronize the port numbers that corresponding ports information is this member device
MAC Address, and synchronize the MAC Address that corresponding ports information is aggregation group mark, according to described to be synchronized, and
The MAC Address being active, and the end that MAC Address that is described to be synchronized and that be active is corresponding
Message breath and VLAN ID, build broadcasting packet and other member devices in pile system send and make other members set
For being learnt by hardware mac address.
This member device determines the both synchronous study MAC Address to the common port in this locality, and also synchronous study is to polymerization
During the MAC Address that group identifies, by all to be synchronized, and the MAC Address being active is synchronized to other
Member device.
This member device, when synchronizing MAC Address, synchronizes MAC ground to be synchronized by the way of building broadcasting packet
Location.
This member device is to be synchronized by each, and the MAC Address being active is as the source of broadcasting packet
MAC Address, port information that this MAC Address that is to be synchronized and that be active is corresponding and VLAN ID,
On the position that can learn when carrying hardware study MAC Address in the broadcasting packet built.
So, build a broadcasting packet respectively for all MAC Address to be synchronized, be sent in pile system
Other member devices so that it is his member device can learn to the MAC Address synchronized.
No matter step 202 and step 203 determine which MAC Address of synchronization, is all the MAC that will be active
Address synchronization, the MAC Address being in ageing state is the most asynchronous.
Each member device, when study is to a MAC Address, all can arrange ageing time for this MAC Address, always
In the change time, the state that this MAC Address is corresponding is state of activation, ageing time then, by this MAC Address swash
Status modifier of living is ageing state, then waits Preset Time, deletes the list item that this MAC Address is corresponding.
Embodiment two
After each member device sends the broadcasting packet synchronizing MAC Address, other member devices can be received by stacking opening
To this broadcasting packet.

The content of the broadcasting packet received carries out hardware mac address study.Detailed process is as follows:
When member device receives, by stacking opening, the broadcasting packet that other member devices synchronize MAC Address, according to this
The source MAC of broadcasting packet, and the VLAN ID that carries in broadcasting packet and port information are at local mac
Address list item mates.
If mated completely, if the state of MAC Address corresponding to this source MAC is ageing state, it is updated to swash
The state of living；If matching source MAC and VLAN ID, and do not match the end that this source MAC is corresponding
Message ceases, and carries out MAC Move process；Otherwise, learnt by hardware mac address, by the source of this broadcasting packet
MAC address learning is in MAC Address list item, and the state of this source MAC is set to state of activation.
When the VLAN ID carried in the source MAC of this broadcasting packet, and this broadcasting packet and port information,
When local mac address table is fully able to match, if this source MAC is located in MAC Address list item
In state of activation, do not process；If this source MAC is in ageing state in MAC Address list item,
Then the state that this source MAC is corresponding in MAC Address list item is updated to state of activation.
If the VLAN ID carried in the source MAC of this broadcasting packet, and this broadcasting packet and port information,
Local mac address table is only capable of match source MAC and VLAN ID completely, and port information does not mates,
Illustrate to there occurs MAC Move situation.Carry out MAC Move process, implement and be deletion this source MAC ground
The list item that location is corresponding in mac address table.
If the source MAC only matched in broadcasting packet, and this source MAC would be right in mac address table
The VLAN ID answered, inconsistent with the VLAN ID that broadcasting packet carries；Or, not in mac address table
It is fitted on the source MAC of this broadcasting packet, then this broadcasting packet is learnt by hardware mac address, by this broadcast
The source MAC of message learns in MAC Address list item.
This member device is learnt by hardware mac address, learns the source MAC of this broadcasting packet to MAC
In address list item, including:
This member device by the source MAC of this broadcasting packet, and the port information that carries of this broadcasting packet and
VLAN ID binding learns in described MAC Address list item.
