A kind of synchronization processing method for running on above-mentioned line card is provided in the present embodiment, and Fig. 2 is according to of the invention real
The flow chart of the synchronization processing method of example is applied, as shown in Fig. 2 the flow comprises the following steps：
Step S202, First Line card learn MAC address by network processing unit NP；
Step S204, First Line card send MAC synchronous multicasting messages by NP to other line cards, wherein, MAC synchronous multicastings
Message includes MAC Address.
By above-mentioned steps, because First Line card learns new MAC Address by PN and sends that to carry this new by NP
MAC Address message be can be achieved all line cards in network element MAC Address it is synchronous, travel through the first line card without passing through CPU again
MAC set in all MAC Address, to determine the new MAC Address learnt, therefore, in network element all line cards can and
When the acquisition new study MAC Address, the synchronization process that can solve line card in correlation technique completed by software, it may be difficult to
In time the problem of the change of reflection mac address table, also, compared with prior art, avoiding CPU, over-burden, saves system
Bandwidth, improve MAC synchronous refresh efficiency.
For example, after new MAC is arrived in up NP study, self study mark puts 1 while sends MAC synchronous multicastings message (ibid
MAC synchronous multicasting messages are stated, action type is synchronous), all line cards in network element are transmitted to by switching network and carry out mac learning, with
Realize MAC Address Fast synchronization.
Alternatively, after First Line card sends MAC synchronous multicasting messages by NP to other line cards, in addition to：First
Whether each MAC Address that line card is periodically detected in MAC set persistently receives message, wherein, MAC gathers for storing
MAC Address；First line card refreshes each MAC Address that testing result is yes in MAC set；In First Line card removal MAC set
Each MAC Address that testing result is no.By above-mentioned steps, the MAC for periodically updating the first line card gathers, in case aging is all
MAC Address entries absent corresponding to phase to rear business normal work, and can also quickly delete the non-normal work pair of business
The MAC Address answered, MAC Address corresponding to the non-normal work of the business is being deleted when avoiding waiting for digestion period.
For example, above-mentioned NP periodically detect business corresponding to each MAC Address in MAC set whether normal operation
Cycle duration can be set in the following way：Most long no more than digestion period is set the one of Timing Synchronization refresh cycle
Half, for example digestion period is 60 seconds, then the synchronous refresh cycle be less than 30 seconds.And it is greater than simultaneously in NP traversal mac address tables
All entries need time x.
Alternatively, the first line card refreshes each MAC Address that testing result is yes in MAC set and included：First line card is sentenced
Whether the source identification for each MAC Address that disconnected testing result is yes is predetermined mark, wherein, predetermined mark is each for indicating
MAC Address is the MAC Address learnt by NP；First Line card in the case where the judgment result is yes, by NP to switching network
MAC synchronous refresh messages are sent, to notify MAC Address corresponding to the refreshing of other line cards.
Alternatively, above-mentioned predetermined mark can be self study mark.Pass through above-mentioned steps, it is ensured that only in MAC Address
For self study obtain MAC Address when, just to switching network send MAC synchronous refresh messages, so as to notify other line cards refresh pair
The MAC Address answered, interactive signaling can be reduced.
For example, MAC Address of the up line card to each self study, it is (same that timed periodic sends MAC synchronous multicastings message
Above-mentioned MAC synchronous refresh message), the MAC table of the other all line cards of refreshing, in order to avoid entries absent after aging.
Alternatively, each MAC Address that testing result is no in First Line card removal MAC set includes：Judge detection knot
Whether the source identification for each MAC Address that fruit is no is predetermined mark, wherein, predetermined mark is used to indicate each MAC Address
For the MAC Address learnt by NP；First Line card sends MAC to switching network in the case where the judgment result is yes, by NP
Synchronization removal message, to notify MAC Address corresponding to the deletion of other line cards.Pass through above-mentioned steps, it is ensured that only in MAC
When location is the MAC Address that self study obtains, MAC synchronization removal messages just are sent to switching network, to notify other line cards to delete
Corresponding MAC Address, interactive signaling can be reduced.
For example, after the MAC Address of self study is fallen by NP agings, it is (same with above-mentioned MAC also to send MAC synchronous multicastings message
Step deletes message), all line cards in network element are transmitted to by switching network and carry out specific MAC burin-in process, to realize that MAC Address is fast
Fast aging.In another example after synchronous MAC Address is fallen by NP agings, address is only deleted, does not send MAC synchronous multicasting messages.
Alternatively, the MAC Address of self study safeguards aging position information according to the SMAC of the service message received, synchronous
MAC Address safeguards aging position information according to the MAC sync messages received.
Alternatively, after First Line card learns MAC address by network processing unit NP, in addition to：
Whether available free position stores MAC Address for first line card detection MAC set；First Line is stuck in testing result as in the case of no,
Determine the predetermined priority of MAC Address；First line card is according to the predetermined priority of MAC Address, and priority is less than in gathering MAC
The MAC Address of predetermined priority is covered.Pass through above-mentioned steps, it is ensured that the new MAC Address learnt is stored in safely
MAC gathers.
Alternatively periodic refreshing maintenance mechanism can be with：Up line card is produced using independent Packet Generator timings
A kind of special message completes the transmission of the MAC synchronous multicastings message of each self study MAC entries (action type for synchronous).
Packet Generator are set as that every n seconds are repeated once the operation for refreshing and safeguarding mac address table；In NP traversal mac address tables
All entries, in mac address table effectively and sources of learning be self study entry, one by one send MAC synchronous multicasting messages.
Because sources of learning also assists in NP agings for synchronous MAC Address, the cycle of MAC Address periodic refreshing is old no more than NP
Change the half in cycle, while be also greater than the time that NP travels through whole MAC table entry needs.
NP implementations are given out a contract for a project by NP to realize the synchronization of the MAC Address of all line cards in network element in above-described embodiment.
The dynamic MAC entries of platform caching are mainly used as webmaster and shown, it is not necessary to synchronous to all line cards.MAC address learning source has
Two kinds：It is synchronous, self study.In view of the line card plate in practical application, the complex scenes such as plate, power down, reset are pulled out, the present invention increases
It is subject to lower periodic refreshing maintenance mechanism：Self study MAC Address wants periodic refresh, i.e. timing sends MAC synchronization message messages, by
Switching network is transmitted to all line cards in network element；Self study and synchronous MAC Address, NP can do burnin operation；Increase MAC
Privilege level concept is practised, the MAC Address of self study and synchronous MAC Address judge whether to cover based on priority, and priority is high
Can cover the low MAC entries of priority.
